ABSTRACT:
A light stabile composition for imparting stain resistance to polyamide fiber-containing textile articles (e.g. nylon, wool or silk carpets) comprises a halogenated (e.g. brominated or chlorinated) aryl group-containing product of the condensation polymerization of a hydroxyaryl sulfonic acid (e.g., para-hydroxyphenyl sulfonic acid), a dihydroxydiaryl sulfone (e.g., dihydroxydiphenyl sulfone) and an aldehyde (e.g., formaldehyde). The polyamide fiber-containing textile articles are converted to a stain resistant product by containing the fibers with an acidified aqueous solution of the aforesaid composition.
