  • Patent number: 8910461
    Abstract: Composite yarns, comprising one or more elastomeric fibers and hard yarns, are formed by adhering the elastomeric fibers and hard yarns together using a size material. The size-covered composite yarn can be used in weaving and knitting to make stretch fabrics with desired garment characteristics. The size material may be removed by subsequent wet fabric processing.

  • Publication number: 20070259583
    Abstract: Methods for making stretch fabric having stretch between 10% to 45% in the weft and/or warp direction are disclosed. A corespun composite elastomeric yarn is produced either (a) by low draft (2.7× or below) core-spinning of the elastomeric yarn, or (b) by pretreating the corespun composite yarn in steam or heated water at temperatures of at least 110° C. to reduce yarn power before dyeing or weaving. The fabric with such corespun composite elastomeric yarn in the weft meets end-use specifications without heat-setting.
