Problems solved by technology

Most of the current domestic antibacterial nano-silver is in an ionic state. Its disadvantage is that it is easy to fall off during the washing process. Not only the antibacterial effect will weaken with the use process, but also the fall-off during use will pollute the environment, especially the water environment.

Embodiment 1

[0022] A kind of preparation technology of antibacterial cotton fiber, comprises the following steps:

[0023] a. Fiber pretreatment: place the cleaned cotton fiber in 5g / L sodium hydroxide solution, and treat it for 10 minutes at room temperature;

[0024] b. Prepare silver ammonia solution: Add ammonia water dropwise to 0.01mol / L silver nitrate solution until the initial precipitate is completely dissolved;

[0025] c. Adding nano PU microspheres: adding fibers to the silver ammonia solution configured in step b as nano PU microspheres with a length of no more than 100nm, so that the silver ammonia solution contains 3% nano PU microspheres with a mass fraction;

[0026] d, soaking fiber: immerse the cotton fiber treated in step a into the silver-ammonia solution containing nano-PU microspheres prepared in step c, stir and react for 24h, wherein the mass ratio of fiber to solution is 1:60;

[0027] e, drying for the first time: drying the cotton fiber processed in step d at ...

Abstract

The invention discloses an antibacterial fiber and a preparation technology thereof. The preparation technology of the antibacterial fiber comprises the following steps of a, fiber pretreatment; b, silver ammonia solution preparation; c, nano-PU microsphere adding; d, fiber soaking; e, drying for the first time; f, reduction reaction; g, drying for the second time to obtain the antibacterial fiber. According to the antibacterial fiber and manufactured antibacterial fabric, a fiber texture itself adsorbs the silver ammonia solution, and nano-PU is cross-linked on the surface of a textile fiber;nano-elemental silver is firmly adsorbed on the textile fiber through haptoreaction, an adhering layer of nano-spandex is formed on the surface of the textile fiber so that the antibacterial, smoothand elastic properties of the fabric are increased, and the anti-fuzzing and piling properties and the antistatic property are improved.

Description

technical field [0001] The invention relates to a fiber preparation process, in particular to an antibacterial fiber and a preparation process. Background technique [0002] With the improvement of people's living standards in modern society, people are more concerned about health and environmental protection. They are extremely worried about environmental pollution and the spread of diseases. They hope that germs and viruses will stay away from our lives and create a hygienic, clean and sterile environment. At present, functional home textile products at home and abroad can only be used in special environments, and people expect clean, sterile, healthy and environmentally friendly technological home textile products to enter the homes of ordinary people. [0003] At present, antibacterial agents can be roughly divided into two categories: inorganic series antibacterial agents and organic series antibacterial agents. Organic antibacterial agents have been unable to meet mar...
