Abstract
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. -CH2)3NH2 and -CH2)3NH-CH2CH2-NH2, and polyoxyalkylene-substituted aminoalkyl groups, e.g. -CH2)3NH-CH2-CH(OH)-CH2-O-C2H4O)21(C3H6O)21C8H17. 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.
