Problems solved by technology

Another widely used technology is to add elemental silver particles or nano-material silver-loaded powder to the fiber forming material for spinning to prepare silver-containing fibers. Only the silver on the surface of the fibers in the resulting fibers may exert antibacterial effects, but there are still The problem of being oxidized, and the silver enclosed in the fiber material has almost no antibacterial effect, which not only causes material waste, but also increases product cost

preparation example Construction

[0030] The present invention also provides a preparation method of the above intelligent silver-loaded antibacterial fiber. The technological process of this intelligent silver-loaded antibacterial fiber preparation method is as follows: figure 2 shown, please also refer to figure 1 , including the following steps:

[0031] S1: at least one of acrylic acid, methacrylic acid, acrylate, and methacrylate and acrylamide monomer in a mass ratio of 2:1 to 0.5, and deionized water to prepare an aqueous monomer solution;

[0032]S2: Mix the monomer aqueous solution with the silver ammonia solution, and then add glucose and N, N-methylenebisacrylamide to obtain a perfusion solution; wherein, the silver diammine hydroxide in the silver ammonia solution is in the perfusion solution. The concentration is 0.03g / ml~0.3g / ml, and the amount of N,N-methylenebisacrylamide added is at least one monomer and acrylic acid in the acrylic acid, methacrylic acid, acrylate, methacrylate 0.01% to 1%...

Embodiment 1

[0046] An intelligent silver-loaded antibacterial fiber, the intelligent silver-loaded antibacterial fiber is a core-shell structure, and its structure is as follows figure 1 As shown, it includes a hollow fiber as the shell layer 1 and a core layer 2 formed by silver-containing hydrogel in the cavity of the hollow fiber, that is, the shell layer 1, wherein the side wall of the hollow fiber has no through holes, and the silver-containing water The gel contains elemental silver accounting for 1.5% of the total weight of the intelligent silver-loaded antibacterial fiber.

[0047] The preparation method of the above-mentioned intelligent silver-loaded antibacterial fiber, the process flow of the method is as follows figure 2 shown, including the following steps:

[0048] Step S11: Take polyester hollow fiber filaments with a hollow rate of 25%, a specification of 100D / 24F, and no through holes in the wall, and cut them into 50 pieces of 3m long filaments and form them into tows...

Embodiment 2

[0057] A kind of intelligent silver-loaded antibacterial fiber, its structure is identical with the structure of intelligent silver-loaded antibacterial fiber in embodiment 1, as figure 1 As shown, the difference is that the hydrogel core layer 2 contains silver simple substance accounting for 5% of the total weight of the intelligent silver-loaded antibacterial fiber.

[0058] The preparation method of the above-mentioned intelligent silver-loaded antibacterial fiber, the process flow of the method is as follows figure 2 shown, including the following steps:

[0059] Step S21: Referring to Step S11 of Example 1, the difference is that the hollow fiber used is a polyester hollow fiber filament with no through hole in the wall, a hollow rate of 35%, and a specification of 75D / 36F;

[0060] Step S22: Take 2.55g of silver oxide and dissolve it in 8ml of 10% dilute ammonia water to prepare silver ammonia solution for later use;

[0061] Step S23: Take a 50ml beaker and place it...

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...
