摘要：
A process for felt-proofing and dimensionally stabilizing textiles containing keratinous fibers with a single aqueous bath which contains both reducing agents and polyurethane polymers containing free isocyanate groups as well as polymers or copolymers based on vinyl or divinyl compounds. The aqueous bath has a pH of about 5.5 to about 6.5. The reducing agents used are salts or sulphurous acid or pyrosulphites. The free isocyanate groups of the polyurethane are bound to aliphatic carbon atoms.
