1529345 Fatty acid/hydroxyalkylethylene diamine condensation products HOECHST AG 2 Oct 1975 [4 Oct 1974] 40315/75 Heading C2C [Also in Divisions C5 and D1] An aqueous dispersion contains 20 to 40% by weight of a product obtained by condensing a hydroxyethyl- or hydroxypropyl-ethylene diamine with from 1À2 to 1À8 moles per mole of diamine of a saturated fatty acid of 14 to 18 carbon atoms or its alkyl (up to butyl) ester. The dispersion may be diluted with water and applied to filaments or staple fibres, e.g. of polyacrylonitrile or polyamide, before or after spinning. It improves running in or avoids corrosion of machinery, improves the separating capacity and feel of the fibres and inhibits yellowing.
