This application claims priority from U.S. Provisional Application 60/730,941, filed Oct. 28, 2005.
FIELD OF THE INVENTIONThe present invention relates to composite materials, removable insert liners and completed product constructions with a non-removable liner used in a variety of applications. For example, the liner of the present invention may be employed in a variety of applications including in-line, ice or hockey skates (shell and soft boot) and the like. This liner system composite may be utilized for all weather boots and alpine and hiking applications. The liner is breathable, transfers moisture and waterproof to increase comfort for the skater. The liner may contain thermal fibers, thermal PCM encapsulated molecules or fibers and/or a silica, acrylic, polyester fiber based polymers micro-spheres or the like containing air, polymers or liquid fibers that aid in cooling or thermal regulating temperatures during performance and are capable of absorbing an electrical charge. The micro-sphere encapsulating the air, polymer or electrically sensitive to thermal absorbing material may be constructed of an inherently conductive polymer such as those created by the Polymer Research Institute in New South Wales, Australia.
BACKGROUND OF THE INVENTIONVarious types of liners are known in prior art. These liners are designed to provide certain levels of comfort and durability. Furthermore, in-line skates are also well-known in the art as evidenced by U.S. Pat. Nos. 5,340,132; 5,397,141; and 5,437,466. Of these patents, only U.S. Pat. No. 5,437,466 discloses what is commonly referred to as a “soft-boot”. In other words, the shoe body is made of a soft, pliable material. General statements are provided about the materials used for the shoe body, but not in great detail. All of the patents listed above are hereby incorporated by reference.
However, the liners in ice hockey and in-line skates, as well as snowboard boots, etc., known in the art do not provide the advantages realized by the present invention. With the art of hockey and in-line skating becoming increasingly recreational, numerous categories of skaters are developing in large numbers. The present inventor has recognized the problems faced by the aggressive and the recreational categories of skaters and has developed a liner to overcome such problems.
There is an ongoing need for comfort, moisture transfer, breathability, and support for both removable liners as well as non-removable hockey, ice and soft boot liners. In prior removable liner design, the conventional liner is often constructed with rigid, non-breathable outer materials such as vinyls, foams, and nylons. The inner liners have been leather, nylon, or polyester blends which extremely limited the ability to breathe or wick moisture away from a skater's body. These materials have prevented the foot from breathing adequately. In the case of “shell boot” skates, the plastic material that forms the outer shell boot structure holds the heat and moisture inside the boot. As a result, the lining becomes saturated with sweat which adversely affects the skater's comfort and performance level. This problem is even worse with the aggressive hockey skaters whose needs for proper ventilation are even greater.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide a lining system employing a cooler, warmer, drier and more breathable liner that meets the needs of each individual skater. Accordingly, the liner of the present invention can be accommodated to the needs of skaters of various skill categories by permitting the inner liner material, which is against the foot, to vary in fiber content and construction.
This object of the present invention is realized by providing a lining system having lining materials which acts as a moisture transfer system and poses inherent moisture transfer polymers fibers and absorbent natural and synthetic fibers. The fibers may be combined in knits, wovens, nonwovens or in a combined construction of two or more constructions. An example of a combined construction is a warp-knit fabric such as such as the SENSITIVE Fabrics. Moisture vapors are transferred through the liner from one side to the other side by a multi-layered technically engineered fiber and foam system. In several composite systems the technically nonwoven fibers replace the foam. This is accomplished by utilizing certain materials in a manner determined by the inventor after considerable experimentation and effort. The details of the specific materials as used in the combination are disclosed in the Detailed Description of the Preferred Embodiments.
The moisture transferring lining system of the present invention overcomes the problems in the prior art lining systems and liners and meets the needs of even the most aggressive skaters.
Various other objects, features and advantages of the present invention will become readily apparent in view of the following detailed description of the preferred embodiments in conjunction with the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 5(a) and 5(b) illustrate a sole portion of a shoe constructed according to a preferred embodiment of the present invention.
The following detailed description of the preferred embodiments of the present invention is undertaken in connection with the drawings. This description, while undertaken with respect to the disclosed embodiments, is intended to enable a variety of different applications and slight modifications which form a part of the present invention. More specifically, many of the materials used in this lining system have been developed relatively recently, and in many cases are still being modified and improved.
Where possible, trade names of specific products have been used to assist in the understanding of the invention. The lining system according to the present invention can be easily adapted to accommodate further developments currently envisioned are set forth below.
The elastomeric patent and process patent listed below are hereby incorporated by reference: U.S. Pat. No. 6,074,966, entitled “Nonwoven Fabric Composite Having Multi-directional Stretch Properties Utilizing a Cellular or Foam Layer”, and U.S. Pat. No. 6,479,009 B1, entitled “Method For Producing Nonwoven Fabric Composite Having Multi-directional Stretch Properties Utilizing a Cellular or Foam Layer”.
The elastomeric cellular process is further developed in this application with a combined wet lay and/or dry lay process. The polymer base and aqueous phase are sprayed from the jets and combined during the water jet or air pressurization with the fiber mesh. The selected fiber blend is distributed on a screen bed is fused in one process as the polymer and aqueous phase combine with the fiber surface, react and solidifies. The polymer base reacts and solidifies as the aqueous phase is combined during the pressurization. All three elements, the polymer base, the aqueous phase and the fibers, are fused together with pressure on the screen surface creating an elastomeric, cellular nonwoven product.
This water or air jet combines the polymer base and aqueous solution during the active spray and pressurization and can regulate the amount of polymer or aqueous phase needed for selected performance categories in this invention.
All the nonwovens in this invention are selected for the inherent ability to transfer and/or absorb moisture and may have anti-microbial silver fibers by Foss, Static or the like added to the blend. In a number of options, the fibers included in the inner lining material, or nonwoven top sheet are embedded in the foam and possess anti-microbial, thermal and conductive properties. All of the foam materials used in the present invention are assumed to be breathable, hydrophilic, open-cell and their thickness is variable. Depending on the application, some of the foam materials may not be used and the thickness of any foam material or spacer fabrics that is used can be changed as needed. All the foams in this application may include Microsphere Technology. For example, a foam called Aquazone, Premium, VPF by Foamex, Comfortemp by Frisby or the like, Netsorb by Vita Olympic, CoFoam Hydrophilix, or Dri-Z by Dicon, hydrophilic foam with nonwoven fibers or the like can be used. Preferably, the germicidal, anti-microbial hydrophilic, flocked fiber open-cell hydrophilic foam or a reticulated foam is treated with a surfactant to increase the moisture transfer rate. These chemical friendly additives can be combined directly into the foam polymer or may be applied after the foam is created. A hydrophilic coating such as that created by CIBA Specialty Chemicals (ULTRAPHIL), Wisconsin Global Technology or the like may be added to the foam matrix or nonwoven abutting the foam. The foam can be attached to a non-woven top sheet of synthetic or natural fibers. The fibers may be flocked into the foam or added to the liquid polymer. The preferably, nonwoven fiber selection includes wood pulp and cotton, corn, kapok, lyocel, acrylic, chlorofibre, acetate, wool, hemp, polypropylene, polyester, rayon, LYCRA®, elastine, SPANDEX®, elastine or SPANDEX® or a combination thereof. This top sheet is designed to absorb and move moisture. The addition of LYCRA®, elastine, SPANDEX® or elastine or SPANDEX® to achieve stretchable properties are optional. Evolon®, a product by Freudenberg with or without stretchable properties, may be used as a top sheet option in any layer in this invention. Nonwovens by Freudenberg with elastomeric or stretchable properties are preferred in this invention in some performance categories. However, any nonwoven that is comprised of absorbent and moisture transferring properties with or without stretchable characteristics can be applied. In some options tubular knits can be used for protective gear or skate liner uppers, tongues, heels cups or toe boxes. The nonwoven or nonwoven knitted layer can be ionized to increase the moisture transfer and enhance performance.
The nonwoven may contain one or more combinations of split fibers, hollow fibers, grooved fibers, shaped fibers, anti-microbial fibers or treatments. In some options the nonwoven layer is the inner lining material or outer shell material selection. The moisture transfer nonwoven antimicrobial composite comprised of a moisture transfer nonwoven, open-cell foam layer abutting another moisture transfer nonwoven may comprise the entire liner in a skate, hockey or helmet. The breathable moisture transfer composite system may be enhanced with phase change technologies or additional fiber technology benefits.
The select nature and synthetic fibers and shaped, hollow and split fibers in the nonwoven group have inherent moisture transfer and absorption properties and can be treated with a number of MVT surfactants or wicking solution to increase performance. Intera Technology, Ultraphil, nano-technology or the like are treatments that enhance moisture transfer performance. Nano-technology may be applied to the nonwoven fibers to enhance moisture transfer or waterproof the nonwoven layer. Nano-Technology by Burlington Technologies or Toray Industries is preferable. Cofoam, a hydrophilic foam treatment by Hydrophilix may be applied to the foam or nonwovens to increase the rate of transfer. Coolfix which is developed by Trend Technology, Wisconsin Global Technology or Feran Ice Process may be included in this nonwoven layer fiber, fabric foam layers or combinations in this application. The nonwoven top sheet construction may optionally be replaced by a knitted fiber construction. The nonwoven top sheet or knitted fiber construction may be utilized for a scrum on either side of a foam or thermal nonwoven. The selected nonwoven fiber or blend of fibers may be inclusive in the thermal nonwoven blend, the foam or nonwoven wet-laid, spun bond or needle punch product may be inclusive in the foam. The nonwoven fibers in this application are extremely important and they are selected for the abilities, as stated previously, to transfer moisture, absorb, increase or decrease temperature and provide stability. They are both active and passive in their performance. The polyester fiber inclusive in the nonwoven top sheet, knitted layer or layers of the thermal composites is preferably a shaped fiber such as the 4-8 deep groove polyester fiber or a variation of the shaped polyester fiber preferably, manufactured by the F.I.T Group or the like. A shaped (CCF) fiber by Clemson University or a Technofine polyester fiber by Gelanots may be an option in this layer. These technically engineered polyester shaped fibers provide channels for the moisture to travel along and transfer quickly to the exterior surface. The shaped fabrics may be combined with an active carbon compound such as that by Craghoppers or silica gel which increases the absorbent factor. Response Technology by Craghoppers is an option in this application for the inner lining polyester fibers and nonwoven and/or foam composites. A selection of shaped natural and synthetic fibers as well as polyester such as corn, acrylic, acetate and the like may be included in any layer in the moisture transfer system. The elastomeric cellular composite referenced in the U.S. Pat. No. 6,074,966 may include the selected nonwoven and shaped fibers discussed previously. Optionally, the moisture transfer, breathable, elastomeric composite may be used in place of the nonwoven top sheet on either side of the foam or thermal nonwoven or in place of the selected foam. In some performance categories the moisture transfer, breathable, elastomeric composite may be mechanically or ultrasonically bonded to the inner lining material abutting the foam, nonwoven or thermal nonwoven. The moisture transfer, breathable, elastomeric composite contains synthetic and natural fibers and foam. These fibers may be treated with wetting solutions and/or hydrophilic foam such Cofoam as well as that by Hydrophilix Inc. (U.S. patent application Ser. No. 09/823,129) The moisture transfer, breathable, elastomeric composite may be applied to the thermal nonwoven on either side or be mechanically or ultrasonically bonded to the thermal nonwoven. The moisture transfer, breathable, elastomeric composite may be attached or included in any layer in the moisture transfer system or may be in any layer in the moisture transfer system excluding the exterior shell fabric.
The Cofoam, breathable foam or the like may be used as the selected foam in the moisture transfer, breathable, elastomeric composite or be applied to any layer in the moisture transfer system. Cofoam may be used in place of the selected open-cell foam or in combination with any layer in the moisture transfer system. The Cofoam may be combined with the thermal blend by Foss Manufacturing, INVISTA® thermal nonwovens such as THERMOLITE, Ultrathin or with 3M thermal nonwovens such as THINSULITE, nonwoven by Millennium or the like.
The nonwoven top sheet may be a dry-laid, wet laid, melt blown, spun bond or a needle punch product or a knitted scrum. The selected fibers, fiber construction and treatment of the nonwoven top sheet are a key element in the moisture absorption and transfer properties in the system. The nonwoven may or may not require a wicking solution or treatment. The product category and performance level determines the selection of treatment and the fiber or combination of is a wet laid apertured nonwoven top sheet.
The selected nonwoven top sheets are manufactured by INVISTA® (Sonatra Technology nonwoven), Alhstrom Nonwovens, Dexter Synthetics, Freudenberg nonwovens, Veritex, Nordlys, or the like. All nonwoven fibers in this application possess either active or passive moisture transfer abilities or both. The nonwoven blends may have elastic properties, polymer or silica microspheres or encapsulated PCM technology added with various fibers or fiber blends.
The preferable construction contains cooling and/or heating properties and elastine or SPANDEX® fibers. The Outlast melt spun fiber may be an option in this layer or in the thermal nonwoven layer. In some options the nonwoven fibers in the top sheet may be wrapped by another fiber or coated with hydrophilic foam spray. The foam and fiber composite, nonwoven fabric or the moisture transfer, breathable, elastomeric composite may be coated with a hydrophilic foam such by Hydrophilix or treated with Ultraphil, Coolfix or the like to increase the MVT function and the cooling or thermal application. Optionally, layer 20 may be eliminated when the hydrophilic foam, Cofoam by Hydrophilix or the like is applied or sprayed to the back of the inner lining fabric or material or to the abutting nonwoven. In fact, Cofoam, breathable foam or the like may be substituted for any foam layer in this application creating an extremely thin lining or outer lining moisture transfer composite. The inner lining fabric coated with Cofoam abutting the nonwoven or the nonwoven coated with Cofoam abutting the inner lining material may abut a spacer fabric, a cellulose material by Fox Run, a foam and polymer mesh composite or the outer shell fabric for use in several of the defined categories discussed in this application.
However, in a number of categories the nonwoven abutting the inner lining fabric or material in layer 10 or foam in layer 20 is a thermal spun bond, melt-blown or needle punch product. The preferable thermal nonwoven is a needle punch product by Foss Manufacturing containing a blend of deep groove polyester fibers, silver fibers and natural or synthetic fibers. The nonwoven composite developed by Baychar Technologies and manufactured by Foss Manufacturing referred to as the Foss composites is constructed of a number of layers and contains fibers such as elastine or SPANDEX®, lyocel, PVA, silver fibers, shaped, hollow and/or grooved polyester or like or a blend needled together with or without foam. Alternatively, the nonwoven composite developed at Foss Manufacturing may be constructed with a nonwoven thermal by INVISTA® such as Ultralite, THERMOLITE or the like or the Foss composite may have a 3M nonwoven included such as THINSULITE 100, 200, 300 or the like. These composites transfer moisture and thermally regulate the product by increasing or decreasing the fiber content or treated fibers. Of course, Invista, INVISTA®, 3M and Foss nonwovens may be used in place of the moisture transfer nonwoven composite developed at Foss Manufacturing LLC. in any layer between the inner material and outer shell fabric.
The selected nonwoven thermal, shaped, hollowed or grooved fibers optionally may be flocked to the back side of the inner lining material, the exterior shell fabric or to any foam, foam composite such as the moisture transfer, breathable, elastomeric composite, breathable membrane, thermal or thermal composite containing shaped and hollow fibers with or without a foam layer or polymer layer treatment. Fibers may be flocked as well to the foam inclusive of the nonwoven fibers, nonwoven sheet or polymer mesh. The flocked fiber or blended fibers optionally may be flocked to both sides of the nonwoven, breathable membrane, breathable adhesive or open-cell foam. The thermal nonwoven, THERMOLITE INVISTA® or THINSULITE by 3M optionally may be attached to the foam inclusive of the fibers or polymer mesh or both or may included a foam layer.
The previously mentioned, aperture nonwoven alternatively may be mechanically bonded to the foam layer in 20, 30, 50 on one side or both sides. Optionally, the apertured nonwoven and breathable foam composite combination may be combined with the thermal nonwoven, nonwoven composite with or without a foam material or a flocked composite blend applied to the wet, dry polymer laid nonwoven or foam surface. In some options the nonwoven, foam and polymer mesh layer may be needled or ultrasonically bonded to the thermal nonwoven. The preferred hydrophilic foams are developed by Dicon Foams, Vita Olympic, Hydrophilix, Rubberlite, Lendall, Dynamic, Alpin foams or Foamex foams distributed by Rogers Corporation or the like.
The breathable, foam or foam and nonwoven laminated or welded combinations in layer 20 or 30 as previously suggested may be optionally replaced by a needle punched nonwoven with or without foam, preferably the Foss composite or by the moisture transfer, breathable, elastomeric composite having a foam fused with nonwoven fibers formed in a single process.

Any of these fabrics and nonwoven top sheets may have the selected nonwoven fibers flocked to the back surface or may be laminated to a foam that has the nonwoven fibers flocked into the back of the foam. The additional flocked surface of moisture transfer fibers and optional anti-microbial properties allows increased functionality in the single layer material. All of these fabrics have good moisture transfer characteristics which prevent damage to a skater's or snowboarder's foot by preventing excessive moisture build-up. The moisture transfer inner fabrics may vary in composition and structure in this liner system as fiber technology advances.
This application constructs the following inner lining composite constructions. As stated previously, all inner lining materials and fabrics are laminated, needled, stitched, ultrasonically bonded, adhesively bonded or mechanically bonded to the abutting nonwoven or foam material. The inner lining materials or fabrics may be selected from the previous list.
The first is an inner lining fabric or material abutting an open-cell, hydrophilic foam laminated or needled to a nonwoven material.
The second is an inner lining fabric or material abutting an open-cell, hydrophilic foam where the nonwoven fibers have been flocked into the back of the foam, inner lining fabric or breathable membrane between the inner lining material and foam.
The third is an inner lining material or fabric with an elastomeric cellular composite such as that referenced in U.S. Pat. No. 6,074,966 which is mechanically or ultrasonically bonded to the inner lining material.
The fourth is an inner lining material or fabric abutting a open-cell, hydrophilic foam with the elastomeric cellular composite mechanically or ultrasonically bonded to the foam layer on either side or on both sides.
The fifth inner lining composite construction is an inner lining material or fabric abutting a Foss nonwoven composite constructed of one or more of the following fibers, polyester (preferably 4 Deep Groove by F.I.T. or a variation by Foss Manufacturing), lyocel or acetate, corn, wood pulp cellulose and silver fibers.
The sixth is an inner lining fabric or material with the foam and nonwoven fibers flocked into the back surface.
The seventh is an inner lining fabric or material abutting a foam layer. The foam is inclusive of a nonwoven layer or fibers.
The eighth is an inner lining fabric or material abutting a moisture transfer, nonwoven spacer material. Variations of the inner lining composite are on going and are suggested in multiple combinations. The intent of the moisture transfer system is to provide a complete technical solution in an extremely thin increment to accommodate the comfort needs of the user.
All of the above composite options are presumed breathable and transfer moisture. The inner lining composite abuts second open-cell hydrophilic foam, nonwoven composite of foam and nonwoven and/or a thermal nonwoven, a spacer fabric or polymer mesh and the exterior shell fabric and/or material, skeletal polymer shell or a combination of one or more. A breathable membrane may be inserted between the exterior shell fabric and the nonwoven, spacer product, cellulose material, polymer mesh or foam layer.
In one option, a combination of breathable, foam and nonwoven, a foam and a thermal nonwoven or a foam and spacer fabric or polymer mesh are positioned in layer 30 abutting a spacer fabric, cellulose material or exterior shell material. The above combinations are suggested for use in ice and hockey skates, protective gear, helmets and accessories such as gloves.
The moisture transfer characteristics of the inner liner composite allow moisture vapors to be passed from a skater's or snowboarder's body through the inner liner 10 where it then comes into contact with the first foam material 20. The moisture vapors travel through the first foam material 20 and come into contact with the abutting nonwoven, foam, spacer or cellulose material 30. In some performance categories the aperture nonwoven may be eliminated between layer 20 and 30 or the foam in layer 30 may be a spacer fabric or thermal nonwoven product or composite is applied. The spacer fabric and thermal nonwoven are optional as well in layer 30 and are used to provide comfort and warmth. In the thinner applications such as in the hockey and ice skate, the inner lining composite abuts the outer shell fabric and polymer shell. The performance category determines the materials and combination of materials in layer 30.
In another liner option consists of an exterior shell fabric, a frothed, breathable, open-cell foam or free rise foam abutting a nonwoven or nonwoven thermal layer preferably by Foss Manufacturing, Invista, INVISTA®, 3M or the like and the inner lining material. The breathable foam layer may contain fiber and/or a polymer mesh. Phase Change Technology may be added to the selected nonwoven, flocked fibers or composite or a nonwoven by Outlast, Freudenberg, Alhstrom, Kimberley Clark or the like Wisconsin Global may be used abutting the exterior shell fabric material
As discussed above, first foam material 20 may be a moisture transfer, breathable, elastomeric cellular composite comprised of a layer of germicidal, anti-microbial, open-cell hydrophilic, polyurethane foam such as Foamex foams (VPF, Aquazone®), Dicon foams or the like and a non-woven top sheet. Alternatively, a frothed polymer and fiber combination made in one process can be used in this layer or others All of the foam materials discussed herein are preferably breathable, open-cell, free rise foam, slap foams, frothed foams or foamed coatings made of polyurethane, although not specifically mentioned each time. The inclusive top sheet is preferably composed of wood pulp, rayon, elastine or SPANDEX®, corn, cotton, lyocel, PVA, silver fiber, polypropylene, polyester, or a combination thereof.
Alternatively, foam material 20 can be a foam layer that is separate from the non-woven top sheet and is attached to the non-woven top sheet by lamination, stitch bonding, adhesive or the like. The non-woven top sheet (when used) with or without elastine or SPANDEX® fibers abuts the next layer of 1/16-¼″ reticulated and/or open-cell hydrophilic foam, or second foam material 30. The second foam material 30 (when used) may also be a breathable, germicidal, anti-microbial, reticulated and/or open-cell hydrophilic 1/16/¼″ foam such as Aquazone with or without surfactants, wicking solutions and/or PCM Technologies, Sphere Technology applied or Comfortemp. The first layer 20 or the second foam material in layer 30 may contain a moldable mesh such as that developed by Naltex or Conwed in some embodiments. The polymer mesh inclusive in the open-cell foam or laminated to the open-cell foam can be in applied to any foam layer in this moisture transfer system. The foam may also include a fiber or a group of fibers as well as the polymer mesh. The second foam material is preferably intergraded or backed with a non-woven top sheet as mentioned above. In fact, any of the foam materials discussed herein can be intergraded or backed by such a non-woven top sheet or an elastomeric nonwoven may be applied. The non-woven top sheet is not necessary and can be removed in a number of options. Also, many of the foam materials are interchangeable depending upon specific needs of the skater. The nonwoven apertured top sheet is comprised of cotton, wood pulp, lyocel, silver fiber, PVA, polypropylene or polyester or a combination thereof.
The previous fibers may be flocked into the back of the foam layer 20, 30, or 50 or additional layers. A nonwoven layer, moisture transfer, breathable, elastomeric composite or thermal nonwoven composite may be combined with the foam layer and flocked fibers and foam layer or flocked fibers and inner lining material.
One preferable embodiment for a hockey skate moisture transfer liner combines the inner lining material laminated to a foam layer with flocked fiber backing the inner lining or foam and a spacer fabric or polymer mesh and the exterior shell fabric.

A nonwoven thermal may be a THINSULITE by 3M thermal nonwoven, THERMOLITE by INVISTA® thermal nonwoven, Ssoftherm by Foss manufacturing, or a nonwoven composite with or without foam. A shaped and/or grooved polyester or synthetic fiber nonwoven blend may be combined with one of the selected thermal nonwoven with or without an additional foam layer. Alternatively, the nonwoven composite suggested previously may be a nonwoven fibers and foam layer combined under water or air pressure. The foam layer may be optionally contain elastine, silver or moisture transfer and/or absorbent fibers, a polymer mesh or a combination in a number of performance categories. Alternatively, in one option the foam layer is combined with the fiber or a polymer mesh may have moisture transferring fiber blend flocked to the face side of the foam composite layer or the foam composite may have both sides flocked in some performance categories. The flock blend additional may include nano-technology for soil resistance and anti-microbial properties. This option is recommended for technical climbing footwear, protective gear or apparel.
A moldable foam layer, spacer material or gel or the like may also be used in place of this Flex-guard polymer mesh by Naltrex or the like and the foam composite combination or an air bladder around the heel, toe, cuff or ankle areas. The moldable foam may or may not be a high density, slow recovery foam by Rogers, Rubberlite or the like. If it is not very breathable, it can be made breathable by puncturing. Alternatively, the moldable foam is preferably similar in construction to the second foam material and can be a polyurethane reticulated and/or open-cell hydrophilic, anti-microbial germicidal foam approximately ¼ inch thick (for example Aquazone, Netsorb, Dri-z by Dicon, Hypr-cell by Rubberlite, Comfortemp nonwoven combined with a foam layer, or the like). A non-woven top sheet (with or without apertures) can be attached to the moldable foam. If a moldable foam or spacer fabric is used, then the second foam material may be omitted. Also, the moldable foam can be Aquazone.
As mentioned earlier, the third foam material 50 is preferably similar in construction to the second foam material, namely being either germicidal, reticulated and approximately 1/16″, ⅛″, or ¼″ thick or being germicidal, hydrophilic, and open-cell (for example, Aquazone). This material is preferably laminated to a nonwoven top sheet (which may or may not be apertured) comprised of wood pulp, rayon, cotton, corn, silver fibers, lyocel, polyester, polypropylene, or a combination thereof. The nonwoven or knitted top sheet maybe applied to either side of the foam, spacer fabric or thermal nonwoven to increase moisture transfer. The fibers selected for the nonwoven top sheet may be also used for the flocked fiber blend and be flocked to the any fabric, nonwoven, foam, breathable membrane or spacer material in this liner system. The nonwoven top sheet, when used, abuts the waterproof/breathable membrane 60 and the polymer shell or a combination of fabrics and/or materials and polymer. The nonwoven top sheet may abut an encapsulated outer shell fabric combined with a polymer shell or a combination. An example of a combined fabric and polymer shell composite is the soft shell boot and polymer shell is the Rossignol soft alpine boot or the K2 in-line skate. The exterior shell material is waterproofed with nano-technology, encapsulation, DWR finishes or films, coatings or breathable membranes or ionized treatments.
The suggested nonwoven top sheet fibers maybe flocked on to the foam layer, inner lining material, moisture transfer, breathable, elastomeric composite, breathable membrane or spacer fabric to increase moisture transfer, waterproof and anti-microbial properties.
The anti-microbial flocked fiber composite may be applied to any layer in the composite system.
The nonwoven apertured, top sheet may be optionally mechanically bonded to the thermal nonwoven, foam or to the thermal nonwoven and foam composite to increase the rate of moisture transfer.
The outer shell fabrics may also be treated with waterproof film and finishes or encapsulated fibers or fabrics in some performance categories. The waterproof encapsulated outer shell fabrics eliminate the need for a waterproof/breathable membrane in most categories. However, the breathable membranes such as Gore, Event or the like maybe combined in this application with encapsulation, finishes, films, or coating in some performance categories. In fact, composites of flocked foams fibers or fabrics or nonwoven moisture transfer thermals may be abutting a breathable membrane like Gore, Event, Aquador or membranes by Brookwood or the like. The outer fabrics may also be constructed to repel water with breathable membranes, encapsulated fibers or fabrics, a breathable film or coating. The selected coating and films are breathable and may be used independently or combined with a breathable membrane in some performance categories. The waterproof encapsulation is preferably by Nextec. Nextec is the owner of the Canadian patent CA 1338232 and 593680 application the U.S. Pat. Nos. 4,666,765, 5,004,643, 5,418,015, 5,209,965. The patent documents are hereby incorporated by reference. Encapsulation by Nextec, Toray, ASF and others may be developed in any layer in this moisture transfer system. Preferably the encapsulation is applied to the outer shell fabric listed in this application. Encapsulation by Toray, ASF and others wraps the individual fiber or thread in a polymer base coating. Encapsulation by Nextec coats an internal layer creating a silicon-coated woven fabric substrate (U.S. Pat. No. 5,418,051 or U.S. Pat. No. 5,209,965). Encapsulation allows the moisture vapor to travel around and through the woven, knitted, nonwoven shell fabric, material or elastomeric or combination.
The moisture vapor continues from the second breathable foam material 30 when applied through the mesh or spacer if applied 30, and on through the third exterior foam material 50, nonwoven layer or outer shell material. In some performance categories the spacer fabrics or thermal nonwovens can replace the layer of foam material 50. The moisture vapors are then passed through to the waterproof/breathable membrane 60 or shell material constructed of encapsulated other fabrics, or the like. If the outer fabric is encapsulated, then the moisture vapors pass around the encapsulated fibers and onto the surface fabric. If the liner employs a waterproof/breathable membrane, then the moisture vapors are absorbed into the membrane and passed through to an outer layer of fabric 70, as shown in
Those under the tradenames, Aquador, Entrant Dermizax, Witcoflex, Harrison Technologies membranes, Event, Super Dry Film, Windstopper membrane, Dry comfort, Outdry, Active comfort, Sympatex Windler, Sympatex Elastic, Drytrail, Eclipse, Endurance, Vapex, 2000/Plus/Standard1300, Seco-Tec, Dermizax, Thintech, Lay-tek, Witcoflex Ecodry (by Baxenden Chemical), TX-1540, Outdry, Gore membranes, and PTFE by Tetratec are currently being considered. However, the membranes currently being considered are Aquador, Event and Harrison Technologies. A breathable membrane may be combined with a thermal nonwoven such as THERMOLITE, THINSULITE, Ssoftherm or the moisture transfer nonwoven and foam thermal composite disclosed in this application. Outlast fibers which regulate temperature may be combined in some options with the nonwoven Outlast/Invista® products or other nonwoven blends or foam in this application. If the preceding foam layers are have PCM Technology applied or included in the foam, the Outlast (PCM's) fiber or membrane may be eliminated. These waterproof/breathable membranes are ultra-thin, skin friendly, moisture barriers that allow moisture vapors to escape while preventing outside water from penetrating. Outlast Technology is a Phase Change Technology coated to a membrane, a spun melt fiber or a coating applied to a fabric, foam or nonwoven surface and is manufactured by Gateway Technologies, Freudenberg or Schoeller Textil. Phase Change, micro-encapsulation technology, can adjust to temperature changes and is added to foam. The Phase Change Technology can be combined with nano-technology to cool and transfer moisture in a number of options. Phase Change Materials can be added to a foam layer or adhesive or foamed dot matrix which is applied to a fabric or foam surface or the Phase Change materials may be added to a coated binder and applied foam layer. PCM materials may be further added to foamed adhesive or binder be sprayed to any material surface or fiber. PCM Technology can be added to any fiber, fabric, foam, foam and nonwoven composite, thermal, breathable membrane or flocked fiber blend in this application. Freudenberg Comfortemp nonwovens may be applied to any layer in this composite system or be combined with other nonwovens or foams in this moisture transfer system. The Freudenberg nonwovens or Freudenberg Comfortemp products (W) 02/12607) may be mechanically bonded into the foam or nonwoven layer in this composite system to increase the thermal applications.
A number of patents have been issued to Triangle Research & Development Corp. disclosing the details related to the processes now being employed by Gateway Technologies and Schoeller. For example, U.S. Pat. Nos. 4,756,958 and 5,366,801 are directed to fibers and fabrics with reversible enhanced thermal properties, respectively. The disclosures of these two patents are hereby incorporated by reference. Other patents assigned to Triangle Research & Development Corp. that are related by subject matter and have overlapping inventorship, include U.S. Pat. Nos. 5,415,222; 5,290,904; and 5,224,356. These patents are also hereby incorporated by reference.
Another patent, U.S. Pat. No. 5,499,460, which has overlapping inventorship with the above-mentioned patents, is directed to a moldable foam insole with reversible enhanced thermal storage properties. The disclosure of this patent is hereby incorporated by reference, and is illustrative of one type of moldable foam that can be used as mentioned herein.

The outer layer of fabric 70 of the lining system has 200 to 6000 denier strength and is made waterproof by a membrane, encapsulation technology or a waterproof film. If the waterproof film is applied to the outer fabric, then the membrane or encapsulation technology may be omitted. Encapsulation technology is being utilized by a company called Nectex, Inc. (U.S. Pat. Nos. 5,004,643 and 4,666,765) or Toray, Inc., (a Japanese company or the like). The breathable membranes preserve the outer layer of fabric 70 and perform as a waterproof barrier for the liners. If the encapsulation technology is applied to the outer layer of fabric 70, then the breathable laminate membranes need not be used. The encapsulation technology regulates the degree of waterproofing and breathability of the outer fabric shell by encapsulating an internal layer of fibers within the outer fabric. When the encapsulated fiber layer is close to the fabric surface, the fabric is very waterproof and less breathable. If the layers of encapsulated fibers are in the middle of the outer shell fabric, then the fabric is equally waterproofed and breathable.
The outer layer of fabric 70 is a combination of extremely durable, lightweight materials, Kevlar®/Keprotec products 13207, 13624, 6500, 14705, 65563, 13602, 13408 (manufactured by Schoeller, Inc.), the Schoeller Spirit Line 14138, 14118, 14140, 14120, 14124, 14126, 14128, 14134, 14642, 14643, 14641, 14645, 14636, 14637, 14122, 14132, 14640, Kelvar® and nylon fabrics by Nam Liong, nylon supplex (such as that manufactured by Travis Textiles, Inc. or Blank Textiles, Inc.), nylon Cordora® (manufactured by Schoeller, Inc.), other Cordoras (manufactured by Schoeller or INVISTA®), Maxus 6-ply (manufactured by Blank Textiles, Inc.) or Starlite Dri-lex nylon fabric (manufactured by Faytex Corp.), Mojave or Tudor (both manufactured by Travis Textiles, Inc.), Microft (manufactured by Teijin), Entrant Gil and Dermizax (both manufactured by Toray), Gymstar Plus (manufactured by Unitika), Ultrex High Performance Fabrics (manufactured by Burlington, INVISTA®, Invista, Schoeller, or the like), Nextec synthetic leathers and nonwovens or the like or the like, or other fabrics having similar characteristics as these new products. Nonwovens by Sontara Technologies or the like can be used in combination with outer fabrics and are not to be confused with the nonwoven top sheets attached to the inner foam materials. Instead, this is a high abrasion, moisture transfer, absorbent material that is a spun lace (polypropylene) moisture management product, such as Sontara Technology nonwoven manufactured by INVISTA®, Invista, or nonwoven by Freudenberg for example.
Selecting the proper materials depends upon the needs of each individual skater. The non-abrasive cool fabrics used in the inner liner of the present invention greatly reduce the possibility of trapped moisture, thereby protecting the foot from fungus growth and any damage. The more aggressive skaters or snowboarders need a moisture transfer liner that can remove large amounts of moisture continuously from the foot. These skaters or boarders often do not wear socks, and as a result, calluses, abrasions and blisters become commonplace. A wetting agent may be applied to any of the inner lining materials 20 to enhance the moisture transfer away from the foot. The anti-microbial, anti-fungal polypropylene (polyolefin) fabrics quickly remove moisture away from the foot. Skin damage is minimized because the polypropylene fabric has a smooth, continuous surface. This fabric also prevents bacterial build-up which can cause foot odor and fungus.
The looped polyester terry blend or the like is an excellent wicking fabric and can remove moisture rapidly. A wetting agent by Witco, or the like, may be applied to enhance wickability.
The anti-microbial, anti-fungal Dri-lex nylon and nonwoven fabrics blends are sanded and soft. The material not only removes moisture away from the foot, but is also extremely comfortable and cool to the touch.
The polyester Field Sensor fabric or Intera treated polyesters, polyester blends or the like works well with those individuals who prefer sport or recreational skating. This liner absorbs moisture immediately and is recommended for the soft boot inner liner.
Finally, polyester microfiber fabric is advantageous in that it is cool to the touch, smooth and wickable. A wetting agent treatment enhances wickability.
As a result of using this lining system, the skater continues to have a cooler, drier foot. The lightweight Kevlar®, Starlite, and Cordura®, or the like, outer liner materials are twice as durable as the former heavyweight nylons often used on the outer shell, but function as a softer feeling, breathable outer surface and aid in the moisture transfer.
FIGS. 5(a) and 5(b) illustrate a sole portion 200 of a footpad covered with one of the selected fabrics such as CAMBRELLE® Dri-Lex nylon, Evolon® or Novolon® technology by Freudenberg, polyester blends or the like. Preferably, however, the foot pad is designed using a nonwoven, flocked fibers or Coville fabric. The top sheet is backed by flocked fibers, a Foss nonwoven composite, a hydrophilic moldable nonwoven or foam. The footbed insert protects the foot from abrasion and friction burns. The inserted hydrophilic anti-microbial foam (an open-cell moisture vapor transfer foam) or slow recovery punctured foam foot pad adds support and transfers moisture downward. The bottom portion of the foam is preferably provided with a nonwoven to sheet or flocked fibers as described earlier, a material called SaranClimate Insoles by Fugafil or Sumuntez 1, 2 by Textel may also be used in place of the foam composite foot bed. The heel pocket foam or gel protects the back of the heel with a double layered, breathable, reticulated and/or slow recovery moldable foam or a breathable cellulose material. This cushion protector allows circulation in the heel. The anti-microbial silver fibers, shaped or grooved polyesters, nylon fabric blends or nonwovens or the like, covers a molded hydrophilic open-cell foam free rise or frothed foam or Foss composite 20 that supports the arch and insures the skater of a comfortable stride.
The nonwoven material such as Cambrelle Dri-Lex, Nextec synthetic leathers, nonwovens or fabrics, Evolon® a spun lace, elastine or SPANDEX®, moisture management products by Freudenberg or the like can produce strength and moisture transfer properties to the tongue. It should be understood that these nonwoven materials can always be substituted for the knitted, aero-spacer Dri-lex, even if not specifically mentioned in other parts of this disclosure. This material 340 is wrapped around the outer edge of the tongue to allow moisture vapors traveling from the upper foot area to escape through moisture transfer material 340 to the outer surface of the tongue 300. Material 340 also aids in providing a softer edged tongue. Finally, an outer protective polyurethane layer 350, or the like, is provided over a central portion of the material 340. Another hydrophilic open-cell foam or slow recovery punctured foam (not shown) is shaped to fit between the outer protective polyurethane layer, Cordura® nylons, Kevlar®, or synthetic breathable leathers (by Daowoo Corporation, for example) 350 or the like are surrounded by aero-spacer Dri-lex 340, or a substitute as mentioned above, or the like. The protective polyurethane layer may be optional in both the shell liner and the soft boot. If the protective polyurethane layer is omitted, then the slow recovery foam (not shown) or open-cell foam may also be omitted.
As shown in
In-line, ice and hockey skate tongues have in the past been synthetic hard-edged forms. The shape of these tongues often did not fit the skater's foot. Furthermore, vinyl may damage the upper foot where it meets the inner lining edge during active use of the in-line skate. As a result, the skater may develop blisters, calluses, or bruises on this upper-foot area. MVT brushed microfibers, fabrics and nonwovens blends in this liner system increase performance and prevent foot damage. Additionally, the inner fabrics of the tongue liner have often been non-breathable nylon, nonwovens and vinyl, thereby increasing the possibility of foot bacteria and fungus development. The optional anti-microbial fiber blends and ionized fibers and fabric discourage bacteria and fungus growth.
The liners are preferably provided with a pull tab 90 as illustrated in
The microfiber technology disclosed above is rapidly developing and changing and has greatly increased the potential for improved performance of such products as in-line skates, provided that they are properly utilized as in the present invention. These new products are part of rapidly developing fabric technology. The present invention employs a combination of technical fabrics, open-cell, breathable foam layers, moisture transfer and absorbent nonwovens, breathable spacer fabrics, waterproof/breathable membranes, polymer mesh and cellulose materials, flocked fibers and foams technology, encapsulated technology, nano-technology, structural woven water repellent fabrics, or waterproof film coatings in such combinations that increase the performance of the products in which they are used as well as increase breathability. The waterproof/breathable membranes in this application may have anti-microbial fibers and/or nonwoven fibers flocked to them to increase performance properties. The flocked fiber layer attached to the membrane, outer shell fabric layer or composites layers in this invention may contain silver, corn, lyocel and/or hollow, shaped or split polymer fibers. Nano-technology may be incorporated in any layer in the composite products. Resin treated cotton and synthetics materials by Nano-Tex, NanoHorrizon's E47 fabrics, Nanomatrix fabrics by Toray and Nanosphere technology fabrics by Schoeller can be used for selected inner lining and out shell materials. Coating by Trann Technologies can be applied to SPANDEX®, cotton, and other fabrics. Silicone applications allow for moisture transfer wrinkle free and fad resistant products. Many skate protective products utilize SPANDEX® and stretchable products. The breathable moisture transfer, open-cell high or low density foam and nonwoven composite packages are lightweight and easily molded to accommodate safety helmets, protective gear, skate and technical footwear or apparel.
It should be noted that, in the case of in-line skates, the lining system of the present invention can be applied to both shell boot insert liners and soft boot applications. The soft boot in-line skate mentioned earlier in the background of the invention addressed the needs of a skater to have more flexibility and comfort yet still maintain performance levels. This new technology in the hockey, ice and in-line skate industry has increased tremendously the possibilities of a lighter weight performance product. The soft boot, in-line skate or hockey skate construction can easily accommodate the numerous moisture transfer, breathable composite combinations. The soft boot for hockey, in-line or ice skate use can be constructed with the moldable exterior Kevlar®, Cordura® or the like composites in the moisture transfer system to form tongues, side walls, toe caps and upper applications. While the soft boot does not have a protective shell, it can nonetheless be provided with a permanent integrated liner or a removable liner that enjoys all of the benefits of the present moisture transfer inner lining breathable composite systems. These moisture transfer constructions may also be applied to alpine and hiking boot products. Preferably, the outer shell materials of the moisture transfer system comprising the entire soft boot application would be comprised of a composite combination containing a number of technical fabrics such as nylon, Kevlar®, or high abrasion Cordura® fabric, such as that manufactured by Schoeller, Nam Liong or the like. These fabrics, as well as the high abrasive fabrics, are encapsulated or are provided with a waterproof/breathable membrane or coatings. A breathable, reticulated and/or open-cell hydrophilic, anti-microbial germicidal foam layer by Foamex or Rubberlite or a breathable, anti-microbial, moisture transfer, nonwoven and foam blend manufactured by Foss Manufacturing abuts the encapsulated outer fabric or breathable membrane. The breathable, moisture transfer nonwoven including a foam layer manufactured by Foss Manufacturing may include elastine or SPANDEX® fibers to increase the stretchable properties. In some options the layer of foam may be eliminated and replaced by another nonwoven layer. The structural mesh, combined mesh and foam composite, molded cellulose or spacer material is stitch bonded or laminated to the 1/20-⅛ inch reticulated or open-cell hydrophilic foam. The foam thickness can vary with the products performance criteria. A slow recovery punctured foam or high density foam by Rubberlite, cellulose material, spacer material or silicon gel, or the like, are located in the heel pocket, tongue, and toe areas. An air bladder may also be added around the ankle areas to increase performance in some cases. The structural mesh or molded spacer materials abut a nonwoven top sheet or a foam and nonwoven composite that is laminated, stitched, or ultrasonically bonded to a breathable, reticulated and/or open-cell hydrophilic 1/20-¼ snad inch foam. The ⅛ inch foam abuts preferably a cellular moisture transfer, breathable, elastomeric composite which is laminated to the inner fabric. A nonwoven top sheet laminated to 1/20-⅛ inch foam may also be used in place of the moisture transfer, breathable, elastomeric composite. Also, instead of being removable, the liner would preferably be directly attached to the base of the soft boot by methods well known in the art, such as that disclosed in U.S. Pat. No. 5,437,466. Substitutions can be made to all of the foam materials (i.e. hydrophilic open-cell, Aquazone, Premium, VPF, etc.) just as discussed earlier, and are not specifically repeated here. Spacer fabrics, rubber and nonwoven materials or foam and paper composite combinations may replace any layer in the composite systems. Semi-disposable and disposable composite products may combine one or more fibers such as cotton, corn, flax, hemp, lyocel, wood pulp and/or paper fibers with a foam layer. The disclosed semi-disposable and disposable composite materials maybe combined with a needle punch nonwoven and applied to many end use product lines as a removable and replaceable insert. Other aspects of the present invention can be applied to the soft boot without any significant structural changes. The soft boot density is increased in the footbed, toe box, and heel plate. This added support provides protection and assists in maintaining technical performance levels. The in-line soft boot or shell skate breathability would be greatly enhanced with this added moisture transfer liner system. The soft boot may also employ the nonwoven top sheets and composites in a number of combinations with the foam layers to increase moisture transfer. The breathable moisture transfer system allows moisture to travel through each layer. The performance criteria, product and selected materials determine the rate of moisture transfer and breathability. It is preferable, but not necessary that the outer shell materials are breathable. In many cases a combination of exterior shell materials will allow the moisture and heat to vent in selected areas.
Also, the soft boot outer shell may be a combination of synthetic breathable leather (such as that available from Daewoo, Inc. Nextec or the like), an encapsulated, waterproof film or breathable membrane outer fabric by Gore, Schoeller, Burlington Industries, Malden Performance Fabrics or any of the former fabrics mentioned, or the like, as well as synthetic rubbers, PVC, TAR or CPU, a thermoplastic composite material. Typar Nonwovens by Sontara Technologies, Texon, or the like, may be used in combination with the outer materials in high abrasion areas. These high abrasive polymer materials are not known for moisture transfer or breathability. The suggested composite combination would allow breathable exterior shell materials such as Kelvar® and nylon fabrics to be combined with the less breathable or non-breathable materials in the system.
The outer shell combined materials are then laminated, stitched, adhesively bonded or ultrasonically bonded, or the like, to interior foam or foam and nonwoven layers. An air bladder may be added in combination with or in place of the molded foam and structural mesh to aid in comfort and performance. If the internal layers of foam and nonwovens are stitch bonded, it is recommended that the process with LYCRA®, elastine, SPANDEX® thread by the Xymid group former a Dupont® group be used or the process developed by Tietex with nylon thread, or the like. The outer shell fabric seams may be stitched or adhesively bonded. Alternatively, the outer shell is a moldable composite of shell fabric foam, needle punch thermal nonwoven with or without foam abutting inner lining material. The exterior shell material is bonded to the nonwoven by foam and may optionally include a mesh and/or fibers with anti-microbial properties. The inner lining material may be stitched, laminated or bonded with adhesives, breathable membranes or lamination to the exterior shell composite. The exterior shell fabric material may or may not be waterproofed.
The inner moisture transfer fabrics are any of the former fabrics listed as suggested for the removable liner, or the like. The foam is manufactured by Olympic Vita, Rubberlite, Dynamic foam, Dicon, Foamex or the like, in combination with a nonwoven top sheet as mentioned or the foam-nonwoven combination may be replaced with a foam/top sheet composite referred to as a cellular elastomeric composite. Presently, this invention utilizes shaped polyester fibers (4 deep groved polyester fibers or the like and/or polypropylene filtering material produced by Vitafibers QW 110-QW 150 quiet web or Tangerding Vliesstoffe (TH-FI 210B or FF-FI 250). These materials may be substituted for the reticulated or open-cell foams previously mentioned, materials 30 and 50 for example. The composite combination can be used for apparel, medical, industrial and protective application. Tangerding Vliesstoffe or the like may have an anti-microbial fiber added with the phase change material to increase the performance properties. These breathable, moisture transfer, anti-microbial nonwoven or nonwoven and foam composite combination may be used industrially for air or water filtering applications or baby diapers and medical products. In fact, a large number of the skate composites and combinations of compositions in this invention may be used in medical and industrial applications.
Alternatively, the elastomeric cellular composite or the cellulose spacer material made with wood pulp and elastine fiber or foam materials by FoxRun may be further incorporated anti-microbial fibers. The elastomeric composite or spacer material may have a nonwoven fiber flock on one side or both sides. The elastomeric flocked fiber composite combination is anti-microbial, moisture transfer and thermal regulated and may be applied to numerous composites in this invention for helmet, protective gear, skate, soft boot and alpine shell boots, insert liners, apparel, medical and industrial.
In fact, a large number of the above technical composite combinations may be used to construct the entire product line for protective gear, sporting goods apparel, backpacks, tents, sleeping bags, bouldering shoes, water shoes, cycling shoes, sailing and golf apparel and footwear, as well as, apparel and footwear. In the paddling, water sports products and sailing apparel and accessories, the kapok fiber may be added to increase buoyancy.
The sock 675 is made up of three or four layers and is similar to the thin race boot option. The first layer can be any of the inner liner materials discussed above. The second layer is a layer of moisture transfer, breathable, elastomeric composite, or a foam and nonwoven moisture transfer composite or thermal nonwoven composite comprised of a THERMOLITE, THINSULITE nonwoven with or without foam and silver fibers. The third layer is a material that absorbs and transfers moisture such as an ionized nonwoven blend or a polyester blend manufactured by Deercreek Fabrics, Menra Mills, or Coville fabric treated with a wicking, ionized solution or the like.
The preferable outer shell insert sock construction may be a three-layer composite constructed of an inner lining material, a nonwoven composite with foam or without foam and silver fibers and an outer shell polyester mesh waterproof with a encapsulated, film or a finish. Optionally, a spacer fabric material may replace the inner moisture transfer nonwoven composite layer. The inner lining fabric or material and outer shell layer fabric or material may be a nonwoven, knitted or a woven construction. Encapsulation technology can also be applied to the third layer by Nextec. Sock 675 can be used for additional warmth and is removable, unlike the shoe liner and can be inserted into the snowboard, alpine liner or the like, for extra warmth. The insert sock liner is breathable and preferably used in a boot where the liner is not removable or there is no liner available. The three layers can be attached to one another by lamination, although mechanical bonding, or stitching, or ultrasonically bonded, can also be used. This insert sock liner is recommended for the all-weather boot by L.L. Bean or the like.
The alpine and snowboard race boot requires a thin moldable liner option. The insert liner for the alpine race boot preferably is constructed in following three options the inner lining material abutting an open-cell foam backed with a moisture transfer nonwoven top sheet. The third layer composite is laminated to the moisture transfer, breathable, MVT Thermal made by Foss Manufacturing composite and a spacer fabric material. The exterior shell fabric is laminated to a spacer fabric material.
In the second option the inner lining material is laminated to the moisture transfer, breathable, MVT Thermal developed by Baychar Technologies and manufactured by Foss Manufacturing composite and abuts the breathable moldable spacer fabric and exterior shell material.
In the third option the inner lining material is welded to moisture transfer, breathable, elastomeric composite, the moldable breathable spacer fabric and exterior shell material.
Optionally, the exterior shell fabric may be a three-layer composite constructed of foam, moisture transfer nonwoven and the exterior shell fabric. The three-layer exterior composite may be attached to the breathable spacer fabric and molded. In fact, any of the combinations may be molded, adhesively bonded and welded in this invention.
The microfiber and chemical ionized technology disclosed above is rapidly developing and changing and has greatly increased the potential for improved performance of such products as the alpine boot, provided that they are properly utilized as in the present invention. These new technical fibers, materials, foams and moisture transfer composite combinations are part of rapidly developing technical textiles technology industry. The present invention employs a combination of fabric, foam, moisture transfer nonwovens, moldable spacer materials, breathable membranes, coating, finishes, films, structurally woven or knitted waterproof fabrics, ionized fabrics, encapsulated outer fabrics in such combinations that increase the performance of the products in which they are used as well as increase breathability. The breathable membranes, coating and finishes are optional in alpine, hiking and climbing shoes. The removable sock liner may be inserted into rubber boots, all weather boots or alpine products. The discussion above has focused upon snowboard boots, alpine boots, hiking and climbing shoe liners. Similar applications can be made with running shoes, helmets, protective gear or cross country boots, or in-line skates, gloves, accessories, sleeping bags, back packs and apparel with slight modifications.
In the snowboard boot liner, the various layers can be combined by lamination, mechanical bonding, stitch bonding, ultrasonic bonding or a combination of these two. The second and third layers would include a breathable foam that contacts the first layer and is a germicidal, reticulated foam or a hydrophilic, open-cell foam, such as VPF or Aquazone manufactured by Foamex, DRI-Z manufactured by Dicon with or without glycerin, Phase Change Foam or Schoeller PCM foam or the like. Alternatively, these layers can be a MVT Thermal made by Foss manufacturing composite. An elastomeric cellular composite inclusive of moisture transfer, nonwoven fibers or a open-cell foam backed by a moisture transfer, nonwoven, apertured top sheet composed of wood pulp, polyester, rayon, lyocel, cotton, or polypropylene, in a single process. A foam composite may be used in combination with a thermal nonwoven such as THERMOLITE, THINSULITE or the like.
The fourth layer is a hydrophilic, open-cell preferably, VPF by Foamex, an open-cell, slow recovery foam by Rubberlite, or Dicon Technologies foam, or polymer flex-guard mesh or a polymer flex-guard mesh inclusive in an open-cell foam or a polyester breathable spacer material (by Muller) or the like for support. In this case, the open-cell foam, Foamex, Rubberlite or the like is laminated to a moisture transfer nonwoven top sheet composed of wood pulp, cotton, polyester, lyocel, blend which abuts a waterproof/breathable membrane (fifth layer), if used. If the flex-guard polymer mesh is used, it is included in the foam in one process or the flex guard is followed by another layer of open-cell foam with a moisture transfer nonwoven top sheet inclusive in the foam or abutting the waterproof/breathable membrane or an encapsulated or waterproof breathable coated or filmed exterior shell fabric. If the spacer material is used, it may or may not be molded to accommodate the foot. The moisture transfer nonwoven top sheet may be eliminated in selected performance categories. The breathable spacer material abuts either a waterproof breathable membrane, an encapsulated or coated fabric. The breathable spacer material may be combined with a THERMOLITE or the MVT Thermal developed by Baychar technologies and manufactured by Foss Manufacturing composite.
The Phase Change Technology by OUTLAST/INVISTA or the like may be added to any layer in the liner system and may be combined with encapsulated fibers and fabrics and combined with nanotechnology. Phase Change Technology can be used in conjunction with structurally knitted waterproof fabrics or fibers, or with the encapsulation fabrics by Nextec, Toray or the like. Encapsulation by Nextec combined with the Phase Change Technology or OUTLAST Technologies/INVISTA is an enhanced option in this embodiment, but is not essential in the products. If encapsulation is employed, then the fourth layer preferably includes THERMOLITE with or without split, shaped or grooved fibers or the moisture transfer, breathable, MVT Thermal developed by Baychar Technologies and Foss Manufacturing composite. Both THERMOLITE and the MVT nonwoven developed by Baychar technologies and manufactured by Foss Manufacturing or the like may include anti-microbial properties or silver fibers. If a non-removable liner is employed instead of a removable liner, a waterproof-breathable thin film, finishes or coating can be used instead of encapsulation or a waterproof/breathable membrane, nano-technology may be applied to waterproof any selected outer shell material.
