Abstract
The invention discloses a method for easily preparing antibacterial fibers and textiles by an in-situ complex method. The method comprises the following steps of: dissolving silane coupling agent in an organic solvent to obtain a coupling agent solution, and adding cotton fibers, viscose or textiles for adsorption treatment; placing the adsorbed fibers in air or water-containing solution to react to polymerize the coupling agent and fix the coupling agent on the fibers; and placing the reacted fibers in solution containing inorganic antibacterial ions for adsorption treatment, wherein the silane coupling agent is aminopropyl methyl diethoxysilane. The method is simple in production steps, the antibacterial ions are uniformly distributed inside the cotton fibers, so that the fibers have soft hand-feel and good laundering durability; and the method is applicable to cellulosic fibers and textiles of cellulosic fibers, such as cotton, viscose and flax, and can be used in health-care underclothes, medical gauze, cloths, decorative fabric and the like.
Description
The application is application number: 201210121592.3, the applying date: 2012.04.24, title: the divisional application of " complexes ira situ legal system is for the method for anti-bacterial fibre, fabric ".
Technical field
