ANTIBACTERIAL AND ANTIFUNGAL SYNTHETIC FIBER PRODUCT AND ITS PROCESSING METHOD

摘要

PURPOSE:To provide the antibacterial and antifungal fiber product excellent in washing resistance and maintaining the effects over a long period by a post- treatment method comprising imparting a solution or emulsion containing a specific compound to a synthetic fiber product and subsequently drying the product. CONSTITUTION:The antibacterial and antifungal synthetic fiber product excellent in washing resistance is produced by a post-treatment method comprising imparting N-n-butylcarbamic acid 3-iodo-2-propynyl ester ester to a fiber product such as natural fiber product, synthetic fiber product or semi-synthetic fiber product, e.g. by a padding method or exhaustion method using an organic solvent solution containing the N-n-butylcarbamic acid 3-iodo-2-propynyl ester or using an emulsion containing the compound in the presence of an anionic surfactant or nonionic surfactant. The post-processing method gives the fiber product excellent in washing resistance and having the antibacterial and antifungal effects from a polyester fiber product most difficult to process.
