ABSTRACT:
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.
