Abstract

A novel organopolysiloxane is disclosed which has a molecular structure having, in addition to conventional monovalent hydrocarbon groups bonded to the silicone atoms, aminoalkyl groups, e.g. --CH.sub.2).sub.3 NH.sub.2 and --CH.sub.2).sub.3 NH--CH.sub.2 CH.sub.2 --NH.sub.2, and polyoxyalkylene-substituted aminoalkyl groups, e.g. --CH.sub.2).sub.3 NH--CH.sub.2 --CH(OH)--CH.sub.2 --O--C.sub.2 H.sub.4 O).sub.21 (C.sub.3 H.sub.6 O).sub.21 C.sub.8 H.sub.17. The novel organopolysiloxane, which is soluble or emulsifiable in water without using an emulsifying agent, is useful as the principal ingredient of a fabric-finishing composition and capable of imparting very pleasant touch of softness and excellent antistatic performance to the fabric materials treated therewith.
