Abstract
The present invention relates to the use of a modified fatty amine of formula EQU R--NR.sub.3 --(R.sub.1 --O).sub.n --R.sub.2 (1), wherein PA1 R is C.sub.9 -C.sub.24 alkyl or acyl, R.sub.1 is C.sub.2 -C.sub.4 alkylene, R.sub.2 is hydrogen, C.sub.1 -C.sub.4 alkyl or acyl, R.sub.3 is hydrogen or (R.sub.1 --O).sub.m, n and m are each independently of the other an integer from 2 to 100, and (R.sub.1 --O).sub.n is n identical or different radicals (R.sub.1 --O), and (R.sub.1 --O).sub.m is m identical or different radicals (R.sub.1 --O), for reducing or preventing low molecular weight by-product deposits developing in the course of the polyester fiber material production process on textile materials consisting of polyester fibers or containing these fibers in blends with other fibers.
