Abstract

The invention relates to an intelligent silver-contained antibacterial fiber and a preparation method and an application thereof. The intelligent silver-contained antibacterial fiber is of a core shell structure and comprises a core layer which takes a hollow fiber as a shell layer, is positioned in a cavity of the hollow fiber and is formed by silver-contained hydrogel; no through hole is arranged on the side wall of the hollow fiber; and elemental silver which occupies 0.1-10 percents of the intelligent silver-contained antibacterial fiber in total weight is contained in the silver-contained hydrogel. The intelligent silver-contained antibacterial fiber is safe and nontoxic and has the characteristic that the response is generated when the intelligent silver-contained antibacterial fiber is in contact with water, the release of silver ions is intelligently controlled, and the sterilization is quick and efficient. The preparation method of the intelligent silver-contained antibacterial fiber comprises the following steps of: pouring silver-contained hydrogel monomer solution from one end of the hollow fiber into the cavity of the hollow fiber and forming the silver-contained hydrogel core layer in the cavity of the hollow fiber through heat treatment. Manufactured process equipment is simple and can realize industrial production.

Description

technical field

[0001] The invention belongs to the technical field of functional fibers, and in particular relates to an intelligent silver-loaded antibacterial fiber and its preparation method and application. Background technique

[0002] With the improvement of the quality of human life, people have higher and higher requirements for the safety and hygiene performance of personal products, especially the global climate warming, the growth rate of bacteria and harmful organisms is increasing, and the antibacterial and sterilizing functions of medical dressings and personal hygiene products increasingly important.

[0003] Generally speaking, there will be a large amount of blood or body fluids in the environment where medical dressings or personal hygiene products are used, which is extremely conducive to the growth of bacteria. Therefore, the materials used are required to have a fast-acting antibacterial and bactericidal function.

[0004] Silver ions have broad-spectr...
