Problems solved by technology

However, the traditional antibacterial finishing agents generally use esters or hydroxyl groups to combine with hydrogen bonds in the hydroxyl groups on the fabric. Although the overall fastness is good, after 10 times of washing, the performance drops significantly.

preparation example Construction

[0019] The present invention also relates to a preparation method of a spinning solution, comprising the following steps: 1. Add 1,3-propanediol into a first stirring container, then add graphene powder, and stir evenly (rotating speed is between 150rpm-380rpm ), to obtain a uniform additive solution, and then stand for degassing for 2-6h under a temperature environment of 50°C-55°C, and the temperature during stirring in step 1 is 50°C-55°C, and graphene has an optimal dispersion effect. 2. Add the cupro ammonia spinning solution into the second stirring container, then add the additive solution prepared in step 1, and stir evenly (the rotating speed is between 75rpm-150rpm) to obtain the spinning solution, and the spinning solution after stirring evenly The silk liquid can be spun.

[0020] The present invention also relates to a method for preparing an antibacterial cupro fabric, the preparation method of the antibacterial cupro fabric includes a spinning preparation proce...

Embodiment 1

[0026] Graphene fluffy powder (accounting for 0.015% of the mass of spinning solution), 1,3-propanediol (accounting for 6% of the mass of spinning solution), copper ammonia spinning solution (accounting for 93.985% of the mass of spinning solution);

[0027] The antibacterial high-strength cupro ammonia fabric of this example (86.5g / m 2 ), antibacterial, breaking strength and softness (total average flexural length, the lower the softer) the effect is as follows

[0028] Table 1 Example 1 antibacterial high-strength copper ammonia fabric performance test

[0029]

[0030] The antibacterial high-strength cupro ammonia fabric prepared in this example has higher breaking strength, and its softness is better than that of ordinary cupro ammonia fabric. Not obvious either. This is because the antibacterial graphene is dispersed in the spinning solution to prepare cupro ammonia fibers, and its fixation fastness is excellent. 1,3-propanediol is another main component in the spin...

Abstract

The invention relates to a spinning solution and a preparation method thereof and an antibacterial copper ammonia fabric and a preparation method thereof. The spinning solution is prepared from a copper ammonia spinning solution and an additive solution, and the additive solution is prepared from 1,3-propylene glycol and graphene powder dissolved in the 1,3-propylene glycol. According to the spinning solution, 1,3-propylene glycol and graphene powder are added into the copper ammonia spinning solution for the first time, the two substances are added into the copper ammonia spinning solution according to a strict proportion, the processed copper ammonia fabric has excellent antibacterial performance, the fabric strength can be improved by 30% or above, and the use performance of the fabric is greatly improved.

Description

technical field [0001] The invention relates to a spinning solution and a preparation method, and also relates to a bacteriostatic copper ammonia fabric and a preparation method. Background technique [0002] Cupro fiber is a kind of regenerated cellulose fiber. It is made by dissolving natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution. Cellulose molecular chemicals are decomposed to regenerate cellulose, and the resulting hydrated cellulose is post-processed to obtain cupro ammonia fiber. Because the fiber is soft and lustrous, it is often used as high-grade silk or knitted fabrics. In order to improve the antibacterial properties of fabrics, antibacterial finishing agents are generally used. However, traditional antibacterial finishing agents generally use esters or hydroxyl groups to combine with hydrogen bonds in the hydroxyl groups on the fabric. Although...
