IPC: A41B11/00
Filed: 1991-08-26
Abstract: PURPOSE:To provide the socks having an excellent antimicrobial property by using rayon fibers kneaded with an inorg. antimicrobial agent as a blank material. CONSTITUTION:The above-mentioned antimicrobial socks are knitted of the cotton blended yarn. The cotton blended yarn is formed by blending 10 to 30wt.% rayon fibers and 90 to 70wt.% cotton fibers. The inorg. antimicrobial agent is kneaded at 10 to 15wt.% into the rayon fibers. The inorg. antimicrobial agent consists essentially of aluminum oxide, silicon oxide and magnesium oxide. The antimicrobial socks are constituted by kneading the inorg. antimicrobial agent with the inside of the rayon fibers which are the blank material and, therefore, the antimicrobial effect is less degraded even if the socks are repeatedly washed. The aluminum oxide, silicon oxide and magnesium oxide are incorporated in stone, etc., of the natural world and are, therefore, harmless to the human body.
