  • Patent number: 6839945
    Abstract: The invention relates to a method for preparing a moisture barrier fabric comprising needing the fabric in a direction substantially opposite to the advance direction of the fabric with barbed needles to increase the density of the fabric by entangling the fibers thereof, open-width washing of the needled facecloth fabric with a detergent and sodium carbonate to further increase fabric density by allowing the fabric to neck down or bulk at a substantially random rate, coating one side of the fabric with at least one coating of a latex formulation for use in forming the backcoating of the moisture barrier fabric, comprising a (meth)acrylic acid urethane copolymer having a curing temperature of approximately 250 to 275° F., and immersing the dry moisture barrier fabric, including the latex backing, into a bath of fluorochemical and solution containing about 10 to about 15 wt % polyurethane, and removing excess fluorochemical from the treated fabric.

  • Patent number: 6494362
    Abstract: A fabric is formed of interlacing yarns, and is labeled for ready and accurate identification by a manufacturer. The fabric includes a label carrier yarn selected from at least one end of the interlacing yarns. A fabric identifying label is attached to the label carrier yarn prior to incorporation of the label carrier yarn into the fabric. The label encircles the label carrier yarn in closely spaced relation such that the label avoids interfering with subsequent formation of the fabric.
