The present invention relates to composite materials, removable insert liners and completed product constructions with an non-removable liner used in a variety of application. 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, transfer 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 microsheres or the like containing air, polymers or liquid fibers that aids in cool or thermal regulating temperatures during performance and are capable of absorbing an electrical charge. The microsphere encapsulating the air, polymer or electrically sensitive to thermal absorbing material may be constructed of a 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.
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 and soft boot liners. In prior removable liner design, the conventional liner is often constructed with rigid, non-breathable outer materials such as vinyl's, 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 act 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.
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, tradenames 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.
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 variable. Depending on the application, some of the foam materials may not be the 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, VFI by Foamex, Comfortemp by Frisby, or 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 the 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 coatings 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 or a combination thereof. This top sheet is designed to absorb and move moisture. The fibers have inherent moisture transfer and absorb properties and can be treated with a number of MVT surfactants or wicking solution such as Intera Technology, Ultraphil, Nano-Technology or the like. 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 layers, fiber, fabric foam layers or combinations in this applications. 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 scrums 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 a nonwoven wet-laid, spunbond or needle punch product may be inclusive in the foam. The nonwoven fibers in this application are extremely important and they selected for the abilities as stated previously to move 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-Deep Grove polyester fiber or a variation of the shaped polyester fiber preferably, manufactured by 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 quick to the exterior surface. The shaped fabrics maybe combined with an active carbon compound such as that by Craghoppers or silca gel to which increase 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 the polyester such as corn, acrylic, acetate an the like be included or in any layer in 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 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 elastomeric composite maybe mechanically or ultrasonically bonded to the inner lining material abutting the foam, nonwoven or thermal nonwoven. The elastomeric composite contains synthetic and natural fibers and foam. These fibers may be treated with wetting solutions and/or hydrophilic foam such Cofoam as that by Hydrophilix Inc. U.S. application Ser. No. 09/823,129 The elastomeric may be applied to the thermal nonwoven on either side or be mechanically or ultrasonically bonded to the thermal nonwoven. The elastomeric composite may be attacked or included in any layer in the moisture transfer system or may be any layer in the moisture transfer system excluding the exterior shell fabric.
The Cofoam or the like may be used as the selected foam in the elastomeric composite or be applied to any layer in the moisture transfer system.

The Cofoam may be combination with the thermal blend by Foss Manufacturing Dupont thermal nonwoven such as Thermolite, Ultrathin or with 3MM 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. The select fibers, fiber construction and treatment of the nonwoven top sheet is 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 non-woven top sheets are manufactured by DuPont (Sonatra Technology non-woven), Alhstrom Nonwovens, Dexter Synthetics, Freudenburg Nonwovens, Veritex, Nordlys, or the like. All nonwoven fibers in this application possess either active or passive moisture transfer abilities or both. The nonwoven may have polymer or silca microspheres or encapsulated PCM technology added with various fibers.
The preferably construction s optional to cooling and/or heating properties. The Outlast melt spun fiber may be an option in this layer or in thermal nonwoven layer. In some options the nonwoven fibers in the top sheet may be wrapped by another fiber or coated with a hydrophilic foam. The foam and fiber composite, nonwoven, fabric or the 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 to the back of the inner lining fabric or material or to the abutting nonwoven. In fact the Cofoam or the like may be substituted for any foam layer in this application creating extreme 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 outshell 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 a 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 Foss Composite is constructed of a number of layers and fibers such lyocel, PVA, silver polyester or a blend needled together with or without foam. Alternatively, The Foss composite may be constructed with a nonwoven thermal by Dupont such as Ultralite, Themolite or the like or the Foss composite may have a 3 mm nonwoven included such as Thinsulite 100, 200, 300 or the like. These composites transfer moisture and are thermal regulate the product by increasing or decreasing the fiber contain or treated fibers. Of course Dupont, 3MM and Foss nonwovens may be used in place of the Foss composite in any layer between the inner material and out shell fabric.
The selected nonwoven 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 elastomeric composite, breathable membrane, thermal or thermal composite. Fibers may be flocked as well to the foam inclusive of the nonwoven fibers, nonwoven sheet or polymer mesh.

The eighth is a 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 a 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 another 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 insert between the exterior shell fabric and the nonwoven, spacer product, cellulose material, polymer mesh or foam layer.
In one option a combination of 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 suggested for use in the ice and hockey skates, protective gear, helmets and accessories such as gloves.
The moisture transfer characteristics of the inner liner composite causes moisture vapors to be passed from a skater'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. The spacer fabric and thermal nonwoven are optional as well in layer 30 and are use 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 open cell foam or free rise foam abutting a nonwoven or nonwoven thermal layer preferably by Foss Manufacturing, Dupont, 3MM or the like and the inner lining material. The foam may contain fiber and/or a polymer mesh.

All of the foam material discussed herein are preferably polyurethane, although not specifically mentioned each time. The inclusive top sheet is preferably composed of wood pulp, rayon, corn, cotton, lyocel, PVA, silver fiber, polypropylene, polyester, or a combination thereof.
Alternatively, foam material 20 can be a foam that is separate from the non-woven top sheet and is attached to the non-woven top sheet by lamination, stitch bonding, or the like. The non-woven top sheet (when used) abuts the next layer of ¼″ reticulated and/or open cell hydrophilic foam, or second foam material 30. The second foam material 30 when used may also be a germicidal, anti-microbial, reticulated and/or open cell hydrophilic 1/8/1/4″ 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 backed with a non-woven top sheet as mentioned above. In fact, any of the foam materials discussed herein can be backed by such a non-woven top sheet, but the non-woven top sheet is not absolutely necessary. Also, many of the foam materials are interchangeable depending upon specific needs of the skater. The non woven apertured top sheet is comprised of cotton, woodpulp, 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. A nonwoven top sheet layer, elastomeric composite or thermal nonwoven composite may be combined with the foam and flocked fibers or foam and flocked fibers and inner lining material.

As shown in
As shown in
A nonwoven thermal may be a Thinsulite, 3MM thermal nonwoven, Themolite, Dupont thermal nonwoven, Ssoftherm, or a Foss composite with or without foam. A shaped polyester, or synthetic fiber may be combined with a thermal nonwoven with or without foam. Alternatively, the nonwoven fibers suggested previously may be combined with the thermal or foam. The foam may be combined with the fibers, a polymer mesh or a combination in a number of performance categories. Optional the foam combined with the fiber, mesh or a combination may has fibers flocked to either side or both in some applications.
A moldable foam, spacer material, or gel or the like may also be used in place of this flexguard and foam combination or an air bladder. The moldable foam may or may not be a slow recovery foam by Rogers 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, Comfortemp, 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 flocked to the any fabric, nonwoven, foam, breathable membrane or spacer material in this liner system. The 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 polymer shell or a combination. An example of a combined fabric and polymer shell is the Rossignol soft alpine boot or the K2 in-line skate.
The suggested nonwoven top sheet fibers maybe flocked into the foam, combined with the thermal, inner lining material, elastomeric composite, breathable membrane or spacer fabric. The nonwoven top sheet may be mechanically bonded to the thermal nonwoven, foam or thermal composite on one side or both to provide an increase 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 eliminates the need for a waterproof/breathable membrane in most categories. However, the a 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 maybe 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 use 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, 593680 applications and the U.S. Pat. Nos. 4,666,765, 5,004,643, 5,418,015, 5,209,965. 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 foam material 30 through the meshor spacer if applied 30, and on through the third exterior foam material 50 or outer shell material. If the spacer fabrics or thermal nonwovens are used then the outer layer of foam material 50 may be eliminated in certain performance conditions. The moisture vapors are then passed through waterproof/breathable membrane 60 or the 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, eEvent, Super Dry Film, Windstopper membrane, eEvent, Dry comfort, Outdry, Active comfort, Sympatex Windier, 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, PTFE by Tetratec are currently being considered. However, the membranes currently being considered is 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 disclosed in this application. Outlast fibers which regulates temperature may be combined in some options in the nonwoven Dupont products or other nonwoven blends or foam in this application. If the preceding foam layers are Comfortemp or have PCM Technology applied to the foam, then the Outlast fibers or membrane is eliminated.

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. US (U.S. Pat. No. 5,004,643) (U.S. Pat. No. 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 of encapsulated fibers layer is closes to the fabric surface, the fabric is very waterproof and less breathable. If the layer 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 DuPont), 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, DuPont, 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 DuPont, or nonwoven by Freudenburg 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 need a moisture transfer liner that can remove large amounts of moisture continuously from the foot. These skaters 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 sports 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 coot 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.
The nonwoven material such as Cambrelle Dri-Lex, Nextec synthetic leathers, Evolon a spun lace moisture management products by Freudenburg can product strength and moisture transfer properties to the tongue. It should be understood that these nonwoven materials can always be substituted for the 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, and 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 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 they meet 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 to develop. 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
Abrasive grip fabric 100 is also shown. Texon Aquiline or a Nam liong nylon or kelvar product may be used.
The 6500 high abrasive fabrics manufactured by Schoeller, inc., Nam Liong kelvar and nylon fabrics or the like, are located on the back of the cuff and the top of the toe box, heel, and tongue grip area. The Kevlar and Cordura Starlite fabrics provide comfort and durability to the liners and are extremely strong and resistant to abrasion and allow for breathability and performance.
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 fabrics, foam layers, nonwovens, spacer fabrics, breathable membranes, polymer mesh and cellulose materials, flocked fibers and foams technology, encapsulated 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.
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 boots and soft boots. 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 has numerous combination of the moisture transfer composites prior. The liner of the soft boot can be adapted to this new moisture transfer system. While the soft boot does not have a protective shell, nor a removable liner it can nonetheless be provided with a liner that enjoys all of the benefits of the liner according to the present invention. Preferably, the outer layer of the moisture transfer system for the soft boot application would be a Starlite Dri-lex 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 reticulated and/or open cell hydrophilic anti-microbial germicidal ⅛ inch foam or the anti-microbial nonwoven and foam blend manufactured by Foss Manufactured abuts the encapsulated outer fabric or breathable membrane. The structural mesh, combined mesh and foam composite, molded cellulose or spacer material is stitch bonded or laminated to the ⅛ reticulated or open cell hydrophilic foam. A slow recovery punctured foam, 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 reticulated and/or open cell hydrophilic ⅛″ inch foam. The ⅛″ foam abuts preferably a cellular elastomeric composite which is laminated to the inner fabric. A nonwoven top sheet laminated to ⅛″ foam may also be used in place of the 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. 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 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.
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 DuPont, Schoeller, Burlington, 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.
The outer shell combined materials are then laminated, stitched 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 thread by the Xymid group of DuPont 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, Dicon, Foamex or the like, in combination with a nonwoven topsheet 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 is considering the use of a breathable polyester, shaped polyester (4 deep grove 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 an 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. This combination may be used industrial for air or water filtering applications. 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 by FoxRun may have anti-microbial and/or nonwoven flocked to one side or both sides. The elastomeric flocked composite combinations may be use in numerous combinations for skate, soft boot and alpine shell boots and insert liners, apparel, medical and industrial applications.
In fact, a large numerous of the above composite combinations may be used for protective gear, sporting goods apparel, backpacks, tents, sleeping bags, bouldering shoes, sailing and golf apparel and footwear, as well as, apparel and footwear. In the padding and sailing apparel and accessories the kapok fiber may be added to increase buoyancy.
