Abstract
The invention provides a finish composition for synthetic filament, which does not generate fume and tar at high speed and high temperature, imparts superior lubricity at high temperature, superior antistaticity and yarn winding performance, and has satisfactory biodegradability. The finish composition for synthetic fiber of the invention is characterized by containing one or more of polyether polyester compounds having a molecular weight of 1,000 to 20,000 and represented by the formula: X--(A--B).sub.n --A'--Y. In the formula, each of X and Y is independently hydrogen, or a residue of C.sub.1-8 linear or branched saturated alcohol or C.sub.1-18 fatty acid; each of A and A' is a residue of ethylene oxide/propylene oxide block or random copolymer containing ethylene oxide and propylene oxide from 9:1 to 1:9 mol ratio; B is an aliphatic dibasic acid residue represented as OOC(CH.sub.2).sub.m COO; m is an integer from 1 to 4; and n is an integer from 1 to 3.
