Elastic fabric including elastic fiber and hard yarn and methods for making

USPTO Application #: 20070259583
Title: Elastic fabric including elastic fiber and hard yarn and methods for making
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. (end of abstract)
