Antibacterial working method for fiber

繊維の抗菌加工方法

Abstract

(57)【要約】 【課題】 簡易で経済的な繊維の抗菌加工方法を提 供する。 【解決手段】 抗菌性無機酸化物コロイド溶液を染液と 共に、染浴中に繊維を浸して染色する工程、あるいは、 染液をノズルから噴出させて染色する工程など、通常行 われる種々の染色工程において、繊維に接触させる。抗 菌性無機酸化物コロイド溶液は、0.01〜10重量% の範囲の固形分濃度に調整して、染液と混合して使用す ることが望ましい。該抗菌性無機酸化物コロイド溶液は 安定であり、染液と混合してもゲル化することがない。 抗菌性コロイド粒子は0.01〜5重量%の範囲で繊維 中に含有されるようにすることが望ましい。
PROBLEM TO BE SOLVED: To enable antibacterial working of fiber handily and economically by keeping the fiber in contact with a mixed solution of a dye liquid and an antibacterial inorganic oxide colloidal solution in which fine particles with an average particle size of a specified value composed of an antibacterial metal component and inorganic oxide are dispersed. SOLUTION: Fiber is kept in contact with a mixed solution of a dye liquid and an antibacterial inorganic oxide colloidal solution in which fine particles with an average particle size of 500nm or less composed of an antibacterial metal component and inorganic oxide other than the antibacterial metal component. Hence, the antibacterial working of the fiber in the normal dyeing process eliminates the need of any special treating process for imparting antibacterial performance. As the antibacterial inorganic oxide fine particles (colloidal particles) are so small in the particle size to make a particle size distribution sharp, they have high adhesion strength to the fiber as well as an excellent transparency. In addition, the colloidal particles are fixed accurately on the surface of the fiber by bonding between the electric charge which the colloidal particle has and that which the fiber has.
