ABSTRACT:
Proteinaceous fibers are modified by first contacting the fibers with an aqueous solution of a cupric salt of a carboxylic acid containing from 2-18 carbon atoms and then contacting the so-treated fibers with a hot, semipolar, water-miscible organic solvent. The modified fibers exhibit increased resistance to shrinkage.
