Estimating the term…
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.
A textile material comprising a plurality of yarns, wherein the yarns comprise an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers, wherein the polyphenylene sulfide fibers have a cross-sectional area, the polyphenylene sulfide fibers comprise a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers, and the disperse dye is selected from the group consisting of disperse dyes having a molar mass of about 350 g/mol or more, disperse dyes comprising a nitro group, and mixtures thereof.
A method for dyeing textile materials containing polyphenylene sulfide fibers, the method comprising the steps of:
The method of claim 12, wherein the dye liquor further comprises a volatile organic acid having a boiling point of about 100° C. to about 170° C.
