Embodiment 1

[0030] The preparation method of durable antibacterial textile fiber, comprises the following steps:

[0031] a. Mix nano-scale antibacterial agent nano-silver with polyethylene wax, silica airgel, nylon 6, and high-melt index EVA7660M in a high-mixer for 4 minutes in a mass ratio of 4:8:1:0.8:12, and then Melt and co-extrude with a co-rotating twin-screw extruder, water-cool, pelletize, and dry to obtain antibacterial masterbatch; the co-rotating twin-screw extruder is a 65-type co-rotating twin-screw extruder with an aspect ratio of 42:1 machine;

[0032] b. Add nylon 6, the antibacterial masterbatch obtained in step a, and nylon 6 into three screw extruders to melt, and compound them into silk through a multi-layer die head. The inner layer is nylon 6, the middle layer is antibacterial masterbatch, and the outer layer It is nylon 6, and the mass ratio of the inner layer, the middle layer, and the outer layer is 100:8:70, and then stretched into fibers at a speed of 3200m / m...

Embodiment 2

[0034] The preparation method of durable antibacterial textile fiber, comprises the following steps:

[0035] a. Put the nano-scale antibacterial agent nano-scale titanium oxide, polyethylene wax, silica airgel, nylon 6, and high-melt index EVA40L-03 in a high-mixer with a mass ratio of 3:10:1:0.6:12 3min, then melt co-extrusion with a co-rotating twin-screw extruder, water-cooled, pelletized, and dried to obtain antibacterial masterbatch; to the twin-screw extruder;

[0036] b. Add nylon 6, the antibacterial masterbatch obtained in step a, and nylon 6 into three screw extruders to melt, and compound them into silk through a multi-layer die head. The inner layer is nylon 6, the middle layer is antibacterial masterbatch, and the outer layer It is nylon 6, the mass ratio of the inner layer, the middle layer, and the outer layer is 100:9:60, and then it is stretched into fibers at a speed of 2500m / min, and the spinning oil and deionized water are used in a mass ratio of 1:4. Th...

Embodiment 3

[0038] The preparation method of durable antibacterial textile fiber, comprises the following steps:

[0039] a. Mix the nano-scale antibacterial agent rice-grade zinc oxide with polyethylene wax, silica airgel, nylon 6, and high-melt index EVA220W in a high-mixer for 5 minutes at a mass ratio of 5:10:1:1:13 , then melt and co-extrude with a co-rotating twin-screw extruder, water-cool, pelletize, and dry to obtain antibacterial masterbatch; the co-rotating twin-screw extruder is a 65-type co-rotating twin-screw with an aspect ratio of 42:1 extruder;

Abstract

The invention belongs to the technical field of chemical fiber preparation, and particularly relates to a durable antibacterial textile fiber and a preparation method thereof. The preparation method of the durable antibacterial textile fiber comprises the following steps of a) mixing a nanoscale antibacterial agent with polyethylene wax, silicon dioxide aerogel, nylon 6 and high-melt-index EVA ina high-speed mixer, then performing melt co-extrusion by using a co-rotating twin-screw extruder, and performing water cooling, dicing and drying to obtain antibacterial master batch; b) adding the nylon 6, the antibacterial master batch and the nylon 6 into three screw extruders respectively for melting, performing compounding by using a multilayer die head to form a filament, wherein an inner layer is the nylon 6, a middle layer is the antibacterial master batch, and an outer layer is the nylon 6; then stretching the filament into a fiber, applying spinning oil, performing cold rolling and winding to obtain the durable antibacterial textile fiber. According to the preparation method, the nanoscale antibacterial agent is dispersed in a high-flow system for processing, so that the dispersity of the antibacterial agent is greatly improved; the master batch is independently formed in the middle layer of the spinning, so that on one hand, the antibacterial agent is prevented from fallingoff during washing, and on the other hand, the quality of the nylon 6 such as strength and color cannot be influenced.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber preparation, and in particular relates to a durable antibacterial textile fiber and a preparation method. Background technique [0002] In recent years, with the improvement of people's living standards, the functional requirements of textile fabrics are getting higher and higher. In addition to the conventional requirements of breathability, moisture permeability, lightness, smoothness, antistatic, hydrophilic, moisture absorption, etc., special functions such as antibacterial, self-cleaning, and heat storage are also required. [0003] Antibacterial textiles are currently the fastest growing textiles. Due to the need for antibacterial in various use occasions, antibacterial textiles are currently being used in home textiles, underwear, sweatshirts, clothing for the elderly, pregnant women, and infants. [0004] At present, antibacterial textiles are mainly obtained by adding antibacteri...
