    摘要： Hydrophilic coatings are obtained by applying to a substrate a composition containing an aqueous soluble organopolysiloxane which is capable of being crosslinked by the addition of Si-bonded hydrogen atoms to SiC-bonded aliphatic multiple bonds, and having at least one oxyalkylene unit bonded to a silicon atom and an aqueous soluble catalyst which promotes the addition of Si-bonded hydrogen atoms to the SiC-bonded aliphatic multiple bonds and thereafter crosslinking the organopolysiloxane by the addition of the Si-bonded hydrogen atoms to the SiC-bonded aliphatic multiple bonds to form a hydrophilic coating on the substrate. The aqueous soluble organopolysiloxane may be obtained from a mixture consisting of equal parts of a mixed hydrolysate, prepared from 1.7 moles of dimethyldichlorosilane, 1 mole of [acetoxy-(hexaethyleneoxy)propyl]-methyldichlorosilane and 0.3 mole of vinylmethyldichlorosilane, and a mixed hydrolysate prepared from 1 mole of dimethyldichlorosilane, 1 mole of [acetoxy(hexaethyleneoxy)-propyl]-methyl-dichlorosilane and 1 mole of methyldichlorosilane.

These organopolysiloxanes are preferably prepared by reacting triorganosiloxy end-blocked organopolysiloxanes consisting of diorganosiloxane units, in which at least part of these units contain SiC-bonded oxyalkylene units and, if appropriate, organohydrogensiloxane units or organohydroxyl siloxane units or organoalkoxysiloxane units of mixtures of at least two such monoorganosiloxy units with water in the presence of an acid or base or, and subsequently with a silane or simultaneously with water and a silane in which the silane contains one SiC-bonded monovalent organic radical, or partially hydrolyzed products of the silane. The new organopolysiloxanes are applied to textile fibers to impart hydrophilic properties thereto.
