摘要： 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)n—A′—Y. In the formula, each of X and Y is independently hydrogen, or a residue of C1-8 linear or branched saturated alcohol or C1-18 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(CH2)mCOO; m is an integer from 1 to 4; and n is an integer from 1 to 3.
摘要翻译：本发明提供了一种合成长丝的成品组合物，其在高速高温下不产生烟气和焦油，在高温下具有优异的润滑性，优异的抗静电性和纱线卷绕性能，并且具有令人满意的生物降解性。本发明的合成纤维的成品组合物的特征在于含有一种或多种分子量为1,000〜20,000的聚醚聚酯化合物，由下式表示：X-（A-B）n-A'-Y。在该式中，X和Y各自独立地为氢，或C1-8直链或支链饱和醇或C1-18脂肪酸的残基; A和A'分别是环氧乙烷/环氧丙烷嵌段或含有9:1至1:9摩尔比的环氧乙烷和环氧丙烷的无规共聚物的残基。 B是以OOC（CH 2）m COO表示的脂族二元酸残基; m是1至4的整数; n为1〜3的整数。
