Abstract: Fibers for use in making textiles and floor coverings are made from a moisture management composition that includes polyesters or polyamides and polyoxyalkyleneamines.

Abstract: Acid dye stain-resistant fibers which are formed from a polyamide composition containing a mixture of a masterbatch concentrate, a fiber-forming polyamide and a polymer, the masterbatch concentrate including a carrier and a reagent having the formula: wherein Q and Z are moieties which associate with free acid dye sites in the polyamide, a is an integer from 0 to 2, b is an integer from 1 to 4, and R is an alphatic, aromatic or alicydic hydrocarbyl group. The carrier can be a terpolymer, a semi-crystallic thermoplastic polyester or plyamide having a melting point of about 235° C. or less, or mixtures thereof.

Abstract: A composition for use in making flame-retardant polyester yarns includes about 93 to 99.5% by weight of polyester, from about 0.25 to 4% by weight chain extender, and about 0.25 to 3% by weight polyoxyalkyleneamine.

Abstract: An acid dye stain-resistant fiber-forming polyamide composition comprising a fiber-forming polyamide and a reagent, at least a portion of which associates with free acid dye sites in the polyamide, thereby disabling the acid dye sites in fibers formed from the composition from taking up acid dye stains; a masterbatch concentrate for addition to a fiber-forming polyamide to form an acid dye stain-resistant fiber-forming polyamide composition comprising a carrier compatible with the fiber-forming polyamide combined with an amount of the above reagent in excess of that desired in the acid dye stain-resistant fiber-forming polyamide; as well as fibers and articles of manufacture prepared therefrom.
