Abstract

A composition for shrinkproofing wool which is composed of 1 to 50 weight percent of organopolysiloxanes containing mercaptoalkyl and mercaptoaryl groups and having between 10 to 1000 silicon atoms per mercaptoalkyl or mercaptoaryl group, and 50 to 99 weight percent water, emulsifiers and organic solvents. The use of the composition provides durable shrinkproofing properties in wool and does not adversely affect the handle of the fabric.
