Abstract

The invention discloses a preparation method of a hollow silver-loaded fiber. The preparation method comprises steps as follows: two ends of a hollow fiber are placed in two containers respectively, the two containers are not communicated, a first end of the hollow fiber is immersed in a silver nitrate mixed solution, a second end of the hollow fiber is suspended in one container, and height difference H 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 at a flow rate being 10-100 m / s, the silver nitratemixed solution is enabled to pass the hollow fiber 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, and the hollow silver-loaded fiber is obtained. Silver particles in a sliver particle layer on the inner surface of the hollow fiber obtained with the method are uniform in size and distributed uniformly, and random selection of fiber size and controlled release of the silver particles are facilitated.

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 a layer of antibacterial agent is attached to the surface, which is mainly used in deodorant socks and sanitary carpets. It has a certain antibacterial effect, but the washability is poor, 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 ...
