Abstract
Abstract The interfiber cohesion of filament yarns is improved by applying a fiber-treating agent to a filament yarn and aging, said fiber-treating agent consisting of (a) a high-molecularweight surfactant (A) composed of a copolymer of an anhydride of an unsaturated dibasic acid with a vinyl compound copolymerizable therewith, in which a part of the acid groups are amidated by an aliphatic amine containing at least one aliphatic alkyl group having 1 to 22 carbon atoms and the remaining acid groups are converted to salts of an alkali metal, a lower amine, an alkanol amine or ammonia, and (b) at least one compound selected from the compounds expressed by the following general formulas (1) to (4): WHEREIN R is an alkyl or alkenyl group having 8 to 18 carbon atoms or a residue of a condensate of 1 mole of a higher alcohol having 8 to 18 carbon atoms with 1 to 10 moles of ethylene oxide, X stands for a hydrogen ion, a metal ion, a residue of a polyethylene glycol (the mole number of ethylene oxide being 1 to 5), an ammonium ion or an organic group-substituted ammonium ion, and m and n stand for an integer of 1 to 2 with the proviso that the sum of m and n is 3; WHEREIN R'' is an alkyl, alkenyl or acyl group having 8 to 18 carbon atoms, p, q, r and s stand for an integer of 0 to 5 with the proviso that the sum of p, q, r and s is 1 or more, and m and n are an integer of 1 to 3; WHEREIN R'', m, q, r and s are as defined in above formula (2); AND WHEREIN R, r and s are as defined in above formula (2).
