TEXTILE MATERIALS CONTAINING DYED POLYPHENYLENE SULFIDE FIBERS AND METHODS FOR PRODUCING THE SAME
A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a textile material comprising yarns which contain an intimate blend of polyphenylene sulfide fibers and cellulosic fibers, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180° C. or more to fix the disperse dye to the polyphenylene sulfide fibers.
TEXTILE MATERIALS CONTAINING ARAMID FIBERS AND DYED POLYPHENYLENE SULFIDE FIBERS
A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and aramid fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a plurality of polyphenylene sulfide fibers and aramid fibers; (b) spinning the blend of fibers into a plurality of yarns; (c) forming the yarns into a textile material; (d) subjecting the textile material to a polyphenylene sulfide dyeing process.

DYED TEXTILE HOOK-AND-LOOP FASTENER AND METHOD FOR DYEING TEXTILE HOOK-AND-LOOP FASTENER
A dyed textile hook-and-loop fastener obtained through supercritical CO.sub.2 dyeing of a textile hook-and-loop fastener, is dyed in a deep color, and exhibits a high rupture elongation due to having less thermal history in a dyeing step.
