  • Double face warp knit fabric with two-side effect
    Patent number: 6199410
    Abstract: A fabric with a patterned velvet on one face and a different patterned velour on the other is formed from a three dimensional fabric using a double bar knitting machine. Preferably, at least either the stitching or backing yarn within the fabrics is made with a bulk high enough so that after the three dimensional structure is knitted and split, the back can be napped to form the velour from such yarn.
    Type: Grant

  • Three-dimensional high-low bulk spacer fabric
    Patent number: 6156406
    Abstract: A three-dimensional knit spacer fabric is provided. The fabric includes a first fabric layer, a second fabric layer and yarns interconnecting the two layers. A portion of the yarns interconnecting the two layers is perpendicular to each of the first and second fabric layers, while the remaining interconnecting yarns will be disposed at an angle between the two layers.

  • Three-dimensional sport medical support spacer fabric
    Patent number: 6116059
    Abstract: An integrated 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.

  • Method for constructing a double face fabric and fabric produced thereby
    Patent number: 5855125
    Abstract: A method of constructing a double face fabric is provided. The first step in the method is to knit a three dimensional knit fabric which has a first fabric layer, a second fabric layer and a plurality of yarns that interconnect the two layers. The three dimensional knit fabric is prepared using a conventional double needle bar warp knitting machine. Then, the yarn connecting the two layers is cut, resulting in two pieces of fabric having a velvet surface on one side, and a flat knit surface on the other. The flat knit surface is then raised by a process such as napping to pull portions of the pile yarns through the fabric layer to the technical back, in order to form a pair of double face fabrics, each with a first velvet surface and a second fleece surface. Preferably, the fabric is knit so that after napping it can be stretched. In this manner a wide variety of fabrics can be created.

  • Three-dimensional knit spacer fabric for bed pads
    Patent number: 5817391
    Abstract: An integrated 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 fibers rendered hydrophilic, while the second fabric layer is made from hygroscopic fibers for absorbing moisture.
