Definitions

  • This invention relates to a three-dimensional knit or woven fabric for footwear and backpacks, and more particularly, to a three-dimensional knit or woven fabric having first and second fabric layers spaced from, and connected to, each other.
  • a fabric is for example known from US 5 783 277 A.
  • Prior art footwear and backpack fabrics are generally comprised of a non-integrated, composite fabric with a laminate applied thereto, the laminate acting as a moisture barrier, hindering transport and evaporation of moisture.
  • Another object of the invention is to provide an improved three-dimensional fabric which is sufficiently resilient.
  • Another object of the invention is to provide a three-dimensional fabric which functions as a spacer fabric.
  • an integrated composite three-dimensional knit spacer fabric is provided.
  • the fabric includes a first fabric layer, a second fabric layer, and a resilient yarn interconnecting the two layers.
  • the first fabric layer is made from fiber rendered hydrophilic, while the second fabric layer is abrasion resistant.
  • the three-dimensional spacer fabric of the invention may be used for footwear and backpacks. In all uses, the fabric is constructed such that the bulk ratio of the stitch and pile yarns is controlled.
  • the knit fabric of the invention has a three-dimensional structure. Because of this construction, the fabric acts to cushion the load and protect the wearer.
  • the double-face fabric of the invention may be prepared by knitting a three-dimensional knit fabric on a double-needle bar warp knitting machine commonly used in the manufacture of velvet and well known in the art.
  • the three-dimensional knit spacer fabric is generally indicated at 11 and includes a first fabric layer 13 made from stitch yarn 17, a second fabric layer 15 made from stitch yarn 19, and pile yarn 21 interconnecting the two layers.
  • knit fabric 11 includes backing or lay-in yarns 25 and 26 which are held by stitch yarns 17 and 19 respectively as shown.
  • the yarn that is used is preferably a synthetic material such as polyester, acrylic or nylon.
  • the yarn may be filament or spun, textured or fully oriented.
  • the yarn interconnecting the two layers of the inventive three-dimensional knit spacer fabric should have sufficient resilience and stiffness to keep the two fabric layers apart even if pressure is applied to any one of the fabric layers.
  • the interconnecting pile yarn may be made of either the same or different material than that of the two fabric layers.
  • the yarn may be made of a resilient material such as monofilament or multifilament polyester, nylon, etc.
  • the fabric is designed to facilitate moisture transport away from the body, while maintaining a comfortable top layer and air circulation next to the skin.
  • Top layer 13 is made from fibers rendered hydrophilic to make sure that all moisture is transported through it, thus keeping its surface dry.
  • first fabric or top (back) layer 13 is made from a stitch yarn 17 having a fineness of between 300 and 600 denier and, in one embodiment, with an individual fiber fineness in the range of between 0.3 and 2.5 dpf (denier per Fiber).
  • the backing or lay-in yarn 25 of top layer 13 will be multifilament and will typically have a fineness of between 70 and 200 denier, with, typically, an individual fiber fineness of 0.5 to 5 dpf.
  • stitch yarn 17 and backing yarn 25 of first fabric layer 13 are made of polyester or nylon that has been rendered hydrophilic in order to enhance the transport of perspiration and thereby maintain the skin surface dry.
  • layer 13 is chemically treated or utilizes modified fibers so that it is rendered hydrophilic, as described in U.S. Patent No. 5,312,667.
  • the layer is rendered substantially hydrophilic.
  • the transport of perspiration from the surface especially if the yarn fibers of layer 13 are raised, as described hereinbelow, is substantially enhanced -- liquid moisture is made readily transportable along the surface of the yarn fibers of layer 13.
  • the surface of fabric layer 13 is sanded, brushed or napped and thus comprises a raised surface fabric, with each fiber end being a conductor of moisture.
  • fabric layer 13 will include a plurality of fibers for conducting perspiration therealong from the skin of the wearer and eventually to second fabric layer 15, from where it is evaporated.
  • Pile yarn 21 which interconnects the two layers may be a monofilament or multifilament yarn having a fineness of between 40 and 150 denier, and typically with an individual fiber fineness of 2 to 12 dpf when multifilament. It is preferred, however, that the pile yarn be monofilament in order to increase resilience.
  • the pile yarn is made from fiber rendered hydrophilic in order to facilitate the transport of moisture from top layer 13 to layer 15.
  • each of pile yarns 21 is sufficiently spaced from one another to allow air flow throughout fabric 11 -- this improves cushioning, ventilation and moisture vapor transmission as well as providing for physical protection from objects such as pebbles.
  • outside or back fabric layer 15 is made from stitch yarn 19 which is preferably coarser than the stitch yarn in the first layer.
  • yarn 19 will have a fineness of 150 to 300 denier with typically an individual fiber fineness of 3.0 to 12 dpf.
  • Backing or lay-in yarn 26 typically will also have a fineness of from 150 to 300 denier with typically an individual fiber fineness of 3.0 to 12 dpf.
  • Both stitch yarn 19 and backing yarn 26 will either be multi- or monofilament, with a high tenacity value in order to increase toughness.
  • at least one of, and preferably each of, the yarns 19 and 26 will have a tenacity of between about 3 and 12 grams, preferably about 6 and 12 grams, per denier. This level of tenacity improves abrasion, tear and rupture resistance of fabric layer 15.
  • the fabric of the invention may incorporate an elastomeric yarn such as LYCRA in one or both of lay-in yarns 25 and 26 of layers 13 and 15 respectively.
  • LYCRA elastomeric yarn
  • Such wrap yarn will typically have a total fineness of between about 70 denier and 200 denier of wrap LYCRA. This will enhance the softness and flexibility of the layers, and the tightness of fit.
  • the elastomeric yarn may also be added to the stitch yarn of each layer.
