Abstract: The invention includes a dyed knit, elastic fabric comprising polyethylene terephthalate and spandex. The fabric has staining grade numbers of 4.0 or higher, as measured by staining of multifiber test fabrics in AATCC Test Method 61-1996-2A, and is dyed with disperse dyes comprising azo or anthraquinone molecular groups. The invention further includes a method for making the knit fabric.

Abstract: The invention provides a method for knitting fabric with bare spandex comprising: providing bare spandex yarn; providing hard yarn; drafting the bare spandex; knitting fabric from the hard yarn and the drafted bare spandex with the hard yarn and the drafted bare spandex plated in every course; and contacting the knit fabric with a continuous phase aqueous solution under conditions of temperature and pressure for a time sufficient to set the bare spandex without heating the knit fabric on a tenter frame above 160° C. in air having a relative humidity of less than 50%. The invention further provides a bare spandex-containing knit fabric containing spandex in every knit course that has been exposed to manufacturing process temperature no higher than 160° C. as shown by molecular weight analysis of the spandex and that exhibits wash shrinkage of less than about 14%.
