Abstract
Abstract A process for rendering wool non-felting is provided wherein wool is treated at 20* to 100*C with aqueous preparations which contain a) reaction products of epoxides with at least two epoxide groups per molecule and fatty amines with basic polyamides or dicarboxylic acids and b) adducts of fatty amines with 12 to 22 carbon atoms and 6 to 30 mols of ethylene oxide, esterified with at least dibasic oxygen-containing acids.
