ABSTRACT:
A composition for producing acid dye stain-resistant fibers includes a fiber-forming polymide, a polymer and a masterbatch concentrate which itself includes a reagent and a carrier. The reagent can be an alkal metal, alkaline earth metal or transition metal salt of 5-sulfoisophthalic acid. The carrier can be (A) a terpolymer of an alpha-monoolefin, ethylene-.alpha.,.beta. unsaturated carboxylic acid ester and an internal anhydride of an ethlenically unsaturated carboxylic acid. It can alternatively be (B) a semi-crystalline thermoplastic polyester, (C) a semi-crystalline thermoplastic polyamide, or mixtures of (B) and (C). The polymer in the composition can be (A) and mixtures of (A) and (B) and/or (C).
