However, the nano-silver in the antibacterial fiber prepared by the above method is dispersed on the surface of the fiber by the adhesive, and the nano-silver will gradually lose with the cleaning of the adhesive, resulting in not long-term antibacterial effect and unsatisfactory effect. On the other hand, there are fibers Insufficient strength, cumbersome preparation methods and other shortcomings

Embodiment 1
[0024] The nano-silver particle solution that mass concentration is 5% is diluted to 50ppm, regulates pH=7, cotton fiber is immersed in the nano-silver particle solution of 50ppm 10min with bath ratio 1: 10, makes nano-silver adsorb on the cotton fiber, then puts Put into the drier and carry out spin-drying treatment to obtain the cotton fiber of adsorption nano-silver; Then soak the cotton fiber of adsorption nano-silver into the cellulose xanthate solution (bath ratio 1: 5) that viscosity is 1000CPas and continue 10min, then Dry it in a spinner, then soak it in 5g / L sulfuric acid for 15 minutes, the bath ratio is 1:10, take it out, wash it with hot water and cold water, then dry it with a spinner at high speed, dry it with hot air, and shape it. The antibacterial fiber of the present invention.
Embodiment 2
[0026] Dilute the nano-silver solution with a mass concentration of 5% to 25ppm, adjust pH=8, immerse the cotton fiber in the solution for 30min with a bath ratio of 1:20, make the nano-silver adsorb on the cotton fiber, and then put it into a spin dryer Carry out spin-drying treatment to get the cotton fiber of adsorption nano-silver; Then soak the cotton fiber of adsorption nano-silver into the cellulose xanthate sodium solution (bath ratio 1: 10) of 5000CPas viscosity and continue 20min, then carry out spin-off in spinner. Dry, then soak it in 15g / L sulfuric acid for 30min, the bath ratio is 1:20, finally take it out and wash it with hot water, cold water, dehydration, drying, and setting to obtain the antibacterial fiber of the present invention.
Embodiment 3
[0028] Dilute the nano-silver solution with a mass concentration of 5% to 100ppm, adjust pH=8, immerse the cotton fiber in the solution with a bath ratio of 1:5 for 15 minutes, make the nano-silver adsorb on the cotton fiber, and then put it into a spin dryer The cotton fiber that adsorbs nano-silver is obtained by spinning and drying in the middle; then soak the cotton fiber that adsorbs nano-silver into the sodium cellulose xanthate solution with a viscosity of 50000CPas for 50min, the bath ratio is 1:15, and then spins in a spinning machine. dry, then soak it in a 30g / L sulfuric acid bath for 10min, the bath ratio is 1:10, and finally take it out and wash it with hot water, cold water, dehydration, and dry to obtain the antibacterial fiber of the present invention.

Abstract
The invention discloses an antibacterial fiber with the washing resistance. The antibacterial fiber comprises cotton fiber, and a surface layer is formed on the surface layer of the cotton fiber by compositing nano-silver, viscose and cellulose through a reaction; the cellulose is generated through a reaction generated between cellulose-based xanthogenate and sulfuric acid, and then a cotton fiber core layer and a cotton fiber surface layer which are integrated are formed. The invention further discloses a preparation method of the antibacterial fiber with the washing resistance, a preparation method of an antibacterial textile fabric and the antibacterial textile fabric. Nano-sliver is composited with the cellulose and is not combined with the cellulose through simple physical adsorption, the problem that nano-silver is prone to fall off due to the fact that the property of nano-silver is different from that of the adhesive does not exist, therefore, nano-silver cannot fall off even if the antibacterial fiber is washed multiple times, and not only is the antibacterial effect guaranteed, but also environmental friendliness is achieved. Accordingly, the high sterilization effect can be achieved only through a little amount of nano-silver, broad-spectrum sterilization is achieved, no drug resistance is generated, wound healing can be promoted, and the wide application prospect is achieved in the fields of textile materials, medical instruments and products, furniture and household appliance coatings and the like.
Description
technical field [0001] The present invention is a divisional application of the invention patent application with the application number 201510023120.8, the application date is January 15, 2015, and the title is "an antibacterial fiber and its preparation method". The invention relates to a fiber, in particular to an antibacterial fiber and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] Bacteria are ubiquitous in daily life. Textiles absorb secretions, sweat, sebum and other substances during wearing, which can easily become a breeding ground for bacteria. Under suitable temperature and humidity conditions, bacteria can multiply very quickly. It can reproduce millions of bacteria in a few hours. In the process, not only will the metabolic waste with foul smell be volatilized, but also cause related infectious diseases. Towels, underwear, bed sheets, etc. have thus become the most favorable medium for cross-infectio...
