Abstract

A process for the manufacture of synthetic staple fibers having a marked separating capability by preparing the synthetic fibers with fatty acid-amine-condensation products, which comprises preparing or conditioning the fibers, prior to the textile spinning processes, with fatty acid-hydroxy-alkyl-ethylene-diamine condensation products, the hydroxyalkyl radical or which shows 2 or 3 carbon atoms, and 1 to 2 identical or different radicals of saturated fatty acids having from 14 to 18 carbon atoms are present per mole of hydroxy-alkyl-ethylene-diamine.
