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 moisture-absorbing and sweat-wicking antibacterial polyester filaments, so that polyester fibers have antibacterial properties and good moisture absorption and moisture conductivity

Embodiment 1

[0019] The preparation method of the moisture absorption and perspiration antibacterial polyester filament involved in this embodiment comprises the following steps:

[0020] (1) First pre-crystallize the polyester slices in a crystallizer, the pre-crystallization temperature is 100°C, the pre-crystallization time is 4h, and then ventilate and dry the pre-crystallized polyester slices;

[0021] (2) 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 0.08:100 , the particle size of silver powder is 3-20 μm; mix ethyl orthosilicate with deionized water and ethanol according to the weight ratio of 1:2:4, add hydrochloric acid to adjust the pH value of the solution to 4, and react for 45 minutes at a temperature of 15°C , to obtain a transparent silica sol; add the mixed silver powder into the sil...

Embodiment 2

[0026] The preparation method of the moisture absorption and perspiration antibacterial polyester filament involved in this embodiment comprises the following steps:

[0027] (1) First pre-crystallize the polyester slices in a crystallizer, the pre-crystallization temperature is 160°C, the pre-crystallization time is 2h, and then ventilate and dry the pre-crystallized polyester slices;

[0028] (2) 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 7:100 , the particle size of silver powder is 3-20 μm; mix ethyl orthosilicate with deionized water and ethanol according to the weight ratio of 1:3:4, add hydrochloric acid to adjust the pH value of the solution to 5, and react for 20 minutes at a temperature of 40°C , to obtain a transparent silica sol; add the mixed silver powder into the silica...

Abstract

The invention belongs to the technical field of chemical fiber processing, and particularly relates to a preparation method of moisture-absorbing sweat-releasing antibacterial polyester filament, including the steps of (1), pre-crystallizing polyester chips in a crystallizer, venting and drying the pre-crystallized polyester chips; (2), subjecting silver powder to coating treatment to obtain the silver powder of which the surface is coated with SiO2 and having the grain size being 3-20 micrometers; (3), mixing and melting the polyester chips and the coated silver powder by regulating a screw extruder and an output injection pump; (4), feeding a melt obtained by mixing and melting into a spinning box, spinning by extruding in a spinning assembly through a metering pump to obtain slivers incross structure; (5), subjecting the slivers to cooling by ring air, drafting, elasticizing, winding and packaging finally. Since the silver powder is coated, aggregation of the silver powder is reduced, the polyester fiber has better antibacterial performance, and the silver powder in the fiber is not easy to come 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 moisture-absorbing, sweat-wicking and antibacterial polyester filaments. The antibacterial function of polyester fibers is prepared by utilizing the sterilizing properties of silver ions. Background technique: [0002] Polyester fiber has the advantages of high strength, high modulus, high elasticity, good shape retention and heat resistance, etc. It has become the most widely used fiber variety with the largest consumption. clothing and other fields. Polyester fiber itself has the characteristics of low moisture regain, and its application in some fields with high requirements for hygroscopicity or water absorption is greatly restricted. At present, there have been research results on moisture-absorbing and sweat-wicking polyester filaments or antibacterial polyester filaments, and certain breakthroughs have been made, but t...
