  • Patent number: 11541628
    Abstract: Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights.

  • Patent number: 11377766
    Abstract: Stabilizing a textile sheet structure was achieved by forming a plurality of discrete fiber tufts extending from a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face. Each discrete fiber tuft included a plurality discrete fibers. Each discrete fiber tuft was anchored to the first face and the second face of the fibrous layer by joining together the plurality of each discrete fiber tuft at the first face and the second face and bonding the joined plurality of discrete fiber tuft to the first face and the second face.

  • Patent number: 11339511
    Abstract: Stabilizing a fabric layer and simultaneously laminating a fabric to a bulky and cushioning backing layer using multiple internal adhesive layers placed within the fabric layer forms a composite textile. The melt index, weight and chemical compatibility of the adhesive layers versus the adjacent fabric sub-strata and the backing layer are adjusted to achieve the desired penetration of molten adhesive, mechanical bonding and chemical bonding. An optional external adhesive layer with a low melt index can be added between the fabric layer and the backing layer to facilitate attachment to a highly porous backing.

  • Patent number: 10968554
    Abstract: A fabric made of yarns interlooping with each other or passing through an inner layer at looping intervals. The fabric is embossed with a micro-pattern extending into the yarns or into a layer underneath the fabric. The micro-pattern contains a pre-defined pattern of a plurality of binding points attaching the yarns to the inner layer or to the added underlayer. This micro-pattern has an inter-point spacing between adjacent binding points that is less than the interlooping intervals. The fabric can also be embossed with a macro-pattern separate from and coarser than the micro-pattern. The macro-pattern establishes a desired aesthetic in the fabric, and the micro-pattern does not interfere with the desired aesthetic.

  • Patent number: 10954627
    Abstract: An adhesive layer carrying a uniform color or a color-scheme is placed within or under a colored or color-printed conformable fabric that is simultaneously or subsequently molded into a three-dimensional shape or embossed with a three-dimensional pattern. The thermoplastic adhesive layer proceeds towards the fabric surface and matches or masks the color gaps opened on the surface by molding or embossing. The fabric can also be laminated to a backing during the molding or embossing process.

  • Publication number: 20210054244
    Abstract: A surface covering tile has a plurality of edges extending between the face and the back surface. A pressure sensitive adhesive is disposed on the back surface and covers less than 40% of the back along each one of the plurality of edges where the back surface intersects the plurality of edges. For highly porous back surfaces, the pressure sensitive adhesive is selected and applied in a manner limiting penetration into the back surface. The amount of pressure sensitive adhesive required to affix the tile is reduced, and the tile can be optionally constructed in a manner that facilitates lateral movement of the tile during installation.

  • Patent number: 10738397
    Abstract: A method for directing adhesive places blocking layers adjacent to adhesive layer within a textile sheet structure or between textile sheets, directing adhesive flow in a preferred direction away from the blocking layers. When the blocking layers are partially open to allow some adhesive flow through, adhesive flow is also directed in the planar direction away from closed areas towards open area, and can reform the adhesive layers into a preferred final three-dimensional configuration.

  • Patent number: 10513822
    Abstract: Vacuum printing a fabric involves forming a fabric having a top face and a bottom face and placing a barrier layer below the top face. A plurality of holes is established in the barrier layer, and dye is applied to at least a portion of the top face of the fabric. Vacuum applied to the bottom face pulls the dye through the fabric and the plurality of holes in the barrier layer.

  • Publication number: 20110315023
    Abstract: A cooking pad has a three dimensional surface configuration of peaks and valleys for cooking food. The three dimensional surface configuration elevates the food to a level where it cooks efficiently and evenly. The three dimensional surface configuration rapidly moves liquids expelled from the food during cooking away down depressions and prevents splattering of the liquids back onto the food. The cooking pad may be preformed to the three dimensional surface configuration or may assume this three dimensional surface configuration upon exposure to a cooking environment.

  • Publication number: 20080014817
    Abstract: A composite sheet is disclosed. The composite sheet comprises an open random fibrous web having substantially vertical fibers near a top surface, a first binder resin and a second binder resin, wherein the first binder resin has a melting point lower than the melting point of the second binder resin, wherein the melting point of the second resin is lower than the melting point of the web, wherein the resins are activated in situ with the web fibers to form a resin-fiber rich region on the top surface and wherein the abrasion-resistant sheet can withstand at least about 3,000 cycles on the Wyzenbeek abrasion test using 80-grit abrasive paper. An abrasion-resistant sheet comprising a single binder resin and other abrasion-resistant sheets are also disclosed. Processes for making these abrasion-resistant sheets are further disclosed herein.

  • Publication number: 20050118912
    Abstract: A stretchable stitch-bonded nonwoven fabric is disclosed herein. The fabric includes a nonwoven substrate having basis weight in the range from about 15 to about 150 g/m2, and density in the range from about 0.02 to about 0.12 g/cm3. The nonwoven substrate is bonded with a binder applied to the outer surfaces of the substrate in a liquid form in a sufficiently uniform manner so that no areas greater than the spaces between stitch insertion points are devoid of binder. The binder constitutes from about 2% to about 25% of the total weight of the sum of binder and nonwoven substrate weight. The substrate is stitch-bonded with yarns arranged in a stitch pattern that allows the stitch-bonded fabric to be stretched in at least one direction by a factor of about 2.5 to about 5.0 without forming local ruptures therein, and wherein the stitch-bonded nonwoven fabric can be washed and dried at least twenty times.
