Abstract

The invention relates to a silver plated fiber with an anti-discoloration layer and a manufacturing method thereof, and mainly provides the silver plated fiber with the anti-discoloration layer which can prevent discoloration and has anti-bacterial effect. The silver plated fiber comprises a fiber main body which is formed by fiber materials and comprises an outside surface, a plurality of silveratom agglomerations of which the silver atoms agglomerate in a local area of the outside surface, the anti-discoloration layer and a plurality of fine cracks, wherein the anti-discoloration layer which takes metals selected from titanium, gold, platinum, palladium and the like, and / or an alloy formed from the metals as materials forms a similar film pattern to attach on the outside surface and the agglomeration groups in a mode of film coating, and the fine cracks are formed on the anti-discoloration layer so that the anti-discoloration layer is discontinuous; and therefore the silver atom agglomerations are prevented from discoloring through the anti-discoloration layer and the fine cracks, which has no influence on the anti-bacterial effect of the silver.

Description

technical field [0001] The invention relates to a fiber and its manufacturing method, in particular to a fiber with antibacterial effect and its manufacturing method. Background technique [0002] The origin of antibacterial fiber began in World War II. At that time, Germany used antibacterial-treated fiber fabrics to make military uniforms, which greatly reduced the death rate of the wounded. [0003] At present, the production of antibacterial fibers is mainly carried out in conjunction with the common wet spinning method to obtain the greatest economic benefits. [0004] For example, U.S. Patent No. 6,524,508 proposes to utilize chitin as an antibacterial agent. After dissolving it first, the acrylic fiber is immersed in a solution containing dissolved chitin, so that the chitin is coated on the acrylic fiber to obtain Fiber with antibacterial properties. [0005] Another example is the Japanese Patent No. 9059820, which uses titanium dioxide as an antibacterial agent, ...
