Summary: | PURPOSE:To provide the subject product to a shrink-proof and water-repellent processing to give gold washing resistance, high shrink-proof performance and water-repelling performance to the product, by preliminarily subjecting the animal hair product to a low temperature plasma treatment, imparting a dispersion containing an active isocyanate group-containing compound to the treated product, and subsequently subjecting the product to a thermal treatment. CONSTITUTION:The shrink-proof and water-repellent treatment is performed by preliminarily subjecting an animal hair product to a low temperature plasma treatment, giving an active isocyanate group-having compound to the treated product, imparting a dispersion containing a water-repellent organic fluoro agent to the product, and subsequently thermally treating the treated product. The plasma treatment is preferably performed under conditions comprising a vacuum degree of 1.0Torr, a treating time of approximately 30-180sec, and a heat treat temperature of 130-170 deg.C. |
