PURPOSE:To obtain a fiber product having excellent washing resistance and antimicrobial performances, not damaging human body, by treating yarn with an emulsified dispersion consisting of 3,4,4-trichlorocarbanilide, polyhydric alcohol and cationic dispersant. CONSTITUTION:A yarn product, especially anionic group-containing yarn is subjected to antimicrobial treatment by using an aqueous emulsified dispersion consisting of 3,4,4-trichlorocarbanilide, a polyhydric alcohol or a derivative thereof, especially preferably 0.8% owt 2-ethylhexyl glycol or phenylethylene glycol and 0.8% owt cationic dispersant (e.g., dodecyltrimethylammonium chloride). The yarn treated by this method will not lose antimicrobial effects even by repeated washing, has excellent feeling and causes no yellowing of whiteness. Occurrence of dioxin is not observed in burning. Acrylic yarn, polyamide yarn or cationic dyeable polyester is preferably used as the yarn. |
