Abstract

The invention discloses a preparation method of a hollow silver-loaded fiber. The preparation method comprises steps as follows: a solid substance is arranged in the hollow fiber in a penetrating manner, the hollow fiber with the solid substance is obtained, and the solid substance is not subjected to a reaction with a silver nitrate mixed solution; two ends of the hollow fiber with the solid substance are placed in two containers respectively, the two containers are not communicated, the first end of the hollow fiber is immersed in the silver nitrate mixed solution, the second end of the hollow fiber is suspended in one container, and height difference is formed between the second end and the first end; vertical air blowing is performed at the tail end of the second end of the hollow fiber, the silver nitrate mixed solution is enabled to pass a gap between the hollow fiber and the solid substance and is attached to the inner wall of the hollow fiber, and the hollow fiber with the silver nitrate mixed solution attached to the inner wall is obtained; the hollow fiber with the silver nitrate mixed solution attached to the inner wall is heated and subjected to a reaction, silver ionsare attached to the inner wall of the hollow fiber, and the hollow silver-loaded fiber is obtained.

Description

technical field [0001] The invention relates to a method for preparing silver-loaded fibers, in particular to a method for preparing hollow silver-loaded fibers, and belongs to the technical field of textile fibers. Background technique [0002] In foreign countries, research on antibacterial fibers began in the late 1960s and early 1970s. Metal compounds (mercury, copper, tin, zinc, etc.) were used as antibacterial agents to treat fabrics through certain methods (such as impregnation, adsorption, etc.) , so that the surface is attached with a layer of antibacterial agent, mainly used in deodorant socks and sanitary carpets, with a certain antibacterial effect, but poor washability, and most of these metal compounds are heavy metal compounds, which are highly toxic. After 1975, it was transferred to the research and development of fabrics treated with low-toxic antibacterial agents, such as: organosilicon quaternary ammonium salts developed by Dow Corning in the United State...
