A color hazing or decoloring agent including at least one compound selected from compounds represented by formula (1) and compounds represented by formula (2), and used for color hazing or decoloring of a fabric printed or dyed with a disperse dye:

R.sup.1OOCXCOOR.sup.2(1)

Y.sup.1O-(AO).sub.nY.sup.2(2) wherein, in formula (1), X is an alkylene or alkenylene group of 2 to 4 carbon atoms, R.sup.1 is an alkyl group of 1 to 4 carbon atoms and R.sup.2 is an alkyl group of 1 to 4 carbon atoms, and in formula (2), AO is an alkyleneoxy group of 2 to 3 carbon atoms, n is an integer of 1 to 3, Y.sup.1 is a hydrogen atom or an R.sup.3CO group, R.sup.3 is an alkyl group of 1 to 4 carbon atoms, Y.sup.2 is a hydrogen atom or an R.sup.4CO group, and R.sup.4 is an alkyl group of 1 to 4 carbon atoms.

An ink jet textile printing ink contains at least one water-soluble dye selected from the group consisting of acid dyes, reactive dyes, and direct dyes, a nonionic surfactant with a content in the range of 0.05% by mass to 3.0% by mass relative to the total mass of the ink, and an anionic surfactant with a content in the range of 1 ppm by mass to 100 ppm by mass relative to the total mass of the ink.

Glycol ether benzoates, glycol benzoates and methyl benzoate facilitate the dyeing of the meta-aramid article, e.g., fibers, at or near neutral pH. The addition of an anionic surfactant, such as sodium lauryl sulfate, enhances the performance of the benzoates.

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 dye additive suitable for use in improving the dyeing of aramid fibers includes non-water components dissolved in water. The non-water components include about 20-25% (w/w) sodium or potassium nitrate; about 20-25% (w/w) ketone solvent; about 30-40% (w/w) aromatic solvent; about 1-5% (w/w) of each of glycol ether, biodegradable solvent, acetic acid 56% strength or equivalent or equivalent amount of formic acid, brine salt, sodium or potassium hydroxide, and phenylenediamine, about 1-10% (w/w) of each of a strong acid, hydroxycarboxylic acid, and lanolin; wherein the water makes up about 50-70% of the weight of the dye additive and the non-water components make up about 30-50% of the dye additive. The dye additive may be added to a dye bath at a w/w percentage of about 0.25% to about 6%.
