    • This invention is a method to improve retention of a finish on nylon yarn, said finish containing the reaction product of epichlorohydrin with the reaction product of pyromellitic dianhydride with a long chain fluoroalcohol, comprising polymerizing said nylon in the presence of about 0.5 to 1 mole percent of a primary-tertiary diamine of the structure ##STR1## where R.sub.1 is an alpha, omega-alkylene group of 2 to 10 carbon atoms where cycloaliphatic, R.sub.2 and R.sub.3 are alkyl radicals of 1 to 4 carbon atoms, R.sub.4 is an alkylene radical of 1 to 10 carbon atoms and R.sub.5 is R.sub.4 or arylalkyl, R.sub.6 is H or alkyl of 1 to 4 carbons, so that said nylon polymer is melt stable. Also, for batch processing, polyethyleneimines of 300 to 1200 molecular weight, methylaminobispropylamine, N-(2-aminoethyl)-1,3-propanediamine, and 3,3'-iminobispropylamine are useful.
    • 本发明是一种改善尼龙纱线上饰面保留性的​​方法,所述表面处理剂含有表氯醇与1,2,4,5-苯四酸二酐与长链氟代醇的反应产物的反应产物,包括在约0.5-1摩尔% 其中R 1是2至10个碳原子的α,ω-亚烷基,其中脂环族基,R 2和R 3是具有1至4个碳原子的烷基,R 4是 1至10个碳原子的亚烷基,R 5是R 4或芳基烷基,R 6是H或1至4个碳的烷基,使得所述尼龙聚合物是熔体稳定的。 此外,对于分批处理,分子量为300〜1200的聚乙烯亚胺,甲基氨基丙基胺,N-(2-氨基乙基)-1,3-丙二胺和3,3'-亚氨基双丙基胺是有用的。
