Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, aiming at the fact that the textile fiber nano-silver doped with nano-silver in the prior art is easy to fall off, endangers health and the environment, the antibacterial performance is not durable, and the silver particles are easy to agglomerate and cause the antibacterial effect to decline. Disadvantages, under the premise of mass production and manufacturing, design and seek a preparation method for antibacterial nylon staple fibers, so that nylon fibers have antibacterial properties and antibacterial durability

Embodiment 1

[0015] The preparation method of the antibacterial nylon staple fiber that present embodiment relates to, comprises the following steps:

[0016] (1) Treatment of silver powder: Mix and stir sodium nonylphenoxypropane sulfonate powder with silver powder to reduce the electrostatic force between silver powders. The weight ratio of sodium nonylphenoxypropane sulfonate to silver powder is 0.05:100 , the particle size of silver powder is 3-20μm; the mixed silver powder and SiO 2 Silica sol with a mass percentage of 32% is placed in a magnetic heating stirrer and stirred until the system becomes a uniform suspension. Add ammonia water with a mass fraction of 25% to the suspension and continue to stir until it is in a gel state. Silver powder, silica sol The weight ratio to ammonia water is 1:1:2; then the prepared gel is dried with a blower dryer, and the moisture content is controlled at 0.1-1.5% to obtain a powder; finally, the obtained powder is dried under a nitrogen atmosphere...

Embodiment 2

[0020] The preparation method of the antibacterial nylon staple fiber that present embodiment relates to, comprises the following steps:

[0021] (1) Treatment of silver powder: Mix and stir sodium nonylphenoxypropane sulfonate powder with silver powder to reduce the electrostatic force between silver powders. The weight ratio of sodium nonylphenoxypropane sulfonate to silver powder is 10:100 , the particle size of silver powder is 3-20μm; the mixed silver powder and SiO 2 Silica sol with a mass percentage of 32% is placed in a magnetic heating stirrer and stirred until the system becomes a uniform suspension. Add ammonia water with a mass fraction of 25% to the suspension and continue to stir until it is in a gel state. Silver powder, silica sol The weight ratio to ammonia water is 1:15:20; then the prepared gel is dried with a blower dryer, and the moisture content is controlled at 0.1-1.5% to obtain a powder; finally, the obtained powder is dried under a nitrogen atmosphere...

Abstract

The invention belongs to the technical field of processing of chemical fibers, and particularly relates to a preparation method of antibacterial nylon staple fibers. The preparation method of the antibacterial nylon staple fibers comprises the following steps: (1) carrying out coating treatment on silver powder, wherein the particle size of the used silver powder is 3-20 mu m; (2) preparation of antibacterial chinlon particles: drying the coated silver powder obtained in the first step and chinlon slices by using a blast dryer, and preparing antibacterial chinlon particles doped with the coated silver powder by using a screw extruder; and (3) spinning process: after the antibacterial nylon particles are subjected to the steps of spinning, winding, doffing, bundling, drafting, curling, drying and heat setting, cutting and packaging, preparing the nylon staple fibers with the antibacterial function. By coating treatment of the used silver powder, agglomeration of the silver powder is relieved, the antibacterial effect of the produced nylon staple fibers is good, and the silver powder in the fibers is not easy to fall off.

Description

Technical field: [0001] The invention belongs to the technical field of chemical fiber processing, and in particular relates to a method for preparing antibacterial nylon staple fibers. The nylon staple fibers with antibacterial function are prepared by utilizing the sterilizing properties of silver ions. Background technique: [0002] The scientific name of nylon is polyamide fiber, commonly known as nylon, which has the advantages of high strength, excellent wear resistance and good resilience. Nylon has heat setting properties and can maintain the bending deformation formed when heated. Nylon fabric is known for its excellent wear resistance and light texture, so it is the best choice for sportswear, swimwear, bodybuilding clothes, down jackets, and mountaineering clothes. With the improvement of people's material living standards and the gradual understanding of healthy textiles, people's demand for some functional clothing is increasing. The market prospect of nano-sil...
