Abstract: A process for teating wool and other proteinaceous material to render it shrinkproof which comprises treating the proteinaceous material with a polymerizable treating solution which comprises a urethane-polyisocyanate composition containing (OH)n, (NCO)p and

GROUPS, WHEREIN N IS A NUMBER FROM 0 TO 4.5, P IS A NUMBER FROM 1.5 TO 6 AND N + P IS 3 TO 6, AND Q IS FROM 1 TO 20, WHEREIN THE SAID COMPOSITION CONTAINS TERTIARY NITROGEN, TO THE EXTENT OF AT LEAST 0.05 PERCENT BY WEIGHT AND, THEREAFTER, CURING THE THUSTREATED PROTEINACEOUS MATERIAL WITH WATER.
