METHOD FOR PRODUCING WOOL FIBER PRODUCT GENERATING NEGATIVE ION

摘要

PROBLEM TO BE SOLVED: To efficiently generate negative ions from a wool fiber product with high resistance to washing without deteriorating the touch feeling. SOLUTION: A treating aqueous solution comprising microparticles of an inorganic substance capable of generating the negative ions in air and a wool dissolved substance prepared by dissolving wool and keratinizing the wool and dispersed therein is brought into contact with the wool fiber product and the resultant wool fiber product is then dried and subsequently heat-treated at 100-180 deg.C temperature for 1-15 min.
