Shrinkage Modifications of Wool Fabrics by Sulphite Treatments in Aqueous Organic Solvent Media: Effect of the Organic Solvent on the Internal Lipids

Abstract

If a certain solubilization of lipoproteic material takes place during treatments of knitted wool fabrics with sodium sulphite in an isopropanol/water medium, and if these treatments prevent wool shrinkage at some particular conditions of solvent con centration and temperature, then a relationship exists between the dissolved lipoproteic material and the shrinkproofing effect. The lipids of the fiber play an important role in obtaining this effect.
