Embodiment 1

[0037] This embodiment prepares a kind of modified fiber, and specific implementation process is as follows:

[0038] Step B1: Mix 100g of carbon nanofibers and 280mL of concentrated nitric acid with a mass fraction of 68% to make a suspension, then add 350mL of 20% hydrogen peroxide dropwise to the suspension under stirring, and after the addition is completed Continue to stir and react for 3 hours, then alternately wash and filter with ethanol and water until the pH value of the washing liquid reaches 6, dry the filter cake in vacuum, then grind it in a dry grinder, pass through a 800-mesh sieve after grinding, and obtain the pretreatment fiber;

[0039] Step B2: Mix 100g of pretreated fibers with 32mL of propylene oxide, add 300mL of deionized water and ultrasonically disperse at 28kHz for 20min, then add 45g of ultrafine chitosan powder, stir and react in an ice-water bath for 8h, then heat up to 60°C Continue to stir and react to remove propylene oxide, and finally filte...

Embodiment 2

[0041] The present embodiment prepares a kind of antibacterial protein fiber, and specific implementation process is as follows:

[0042] Step A1: Dissolve sodium carbonate in water and adjust the pH value to 8 to make lye, then take 1kg of uncocooned raw silk and put it into the lye for soaking, stir once every 20 minutes during the soaking process, soak for 2 hours, take out the kneaded silk and use Wash and rinse once, repeat 3 times to remove the colloid on the surface of raw silk, expose the inner silk protein, and obtain degummed silk;

[0043] Step A2: Dissolve 1-butyl-3-methylimidazolium chloride salt in water to form a solution with a mass fraction of 17%, take a small amount of solution and degummed silk and add it to the mixer, heat up to 50±5°C and stir , slowly add the dissolving solution while stirring until the degummed silk is completely dissolved, then pour the dissolving solution dissolved with the degummed silk into the dialysis column, pressurize to 6bar fo...

Embodiment 3

[0046] The present embodiment prepares a kind of antibacterial protein fiber, and specific implementation process is as follows:

[0047]Step A1: Dissolve sodium hydroxide in water and adjust the pH value to 9 to make lye, then take 1 kg of uncocooned raw silk and put it into the lye for soaking, stir once every 20 minutes during soaking, soak for 2 hours, take out and knead Silk and wash once, repeat twice to remove the colloid on the surface of raw silk, expose the inner silk protein, and obtain degummed silk;

[0048] Step A2: Dissolve 1-butyl-3-methylimidazolium chloride salt in water to form a solution with a mass fraction of 22%, take a small amount of solution and degummed silk and add it to the mixer, heat up to 50±5°C and stir , slowly add the solution while stirring until the degummed silk is completely dissolved, then pour the solution dissolved with the degummed silk into the dialysis column, pressurize to 6bar for dialysis, wherein the molecular weight cut-off of ...

Abstract

The invention relates to an antibacterial regenerated cellulose fiber, and belongs to the technical field of antibacterial fibers. The fiber is a composite fiber and is composed of a core bacteriostatic protein fiber and an outer bacteriostatic bamboo fiber, the bacteriostatic protein fiber has good toughness, the bacteriostatic bamboo fiber has good strength, and the bacteriostatic protein fiber and the bacteriostatic bamboo fiber are woven and formed, so that the prepared fiber has good flexibility and strength, and meanwhile, the skin-friendly feeling is kept. According to the antibacterial protein fiber, silk protein is extracted from silk, the silk protein is blended with ultramicro chitosan powder, the modified fiber forms filler, the silk protein is subjected to spinning forming, in addition, cinnamon essential oil is added for kneading, then a water-soluble film layer is coated, volatilization of the cinnamon essential oil is slowed down, in the processes of sweat absorption, washing and the like, the film layer is gradually damaged, and the antibacterial effect is achieved. The cinnamon essential oil is slowly released, and the chitosan is also slowly released, so that the loss of bacteriostatic components of the bacteriostatic bamboo fiber on the surface layer is made up, and the antibacterial bamboo fiber has relatively long-acting antibacterial ability.

Description

technical field [0001] The invention belongs to the technical field of antibacterial fibers, and in particular relates to an antibacterial regenerated cellulose fiber. Background technique [0002] Bamboo fiber is a cellulose fiber extracted from naturally growing bamboo. It has good air permeability, instant water absorption, strong wear resistance and good dyeability. It is widely used in clothing, mats, bed sheets, and curtains. , scarves and other fabrics. [0003] Bamboo fiber contains bamboo kun, which has natural antibacterial and antibacterial effects, but its antibacterial ability is limited when applied to underwear, bed sheets and towels. In addition, the elasticity of bamboo fiber is not good, so it is not soft when applied to clothing. Contents of the invention [0004] In order to solve the technical problems mentioned in the background art, the present invention provides an antibacterial regenerated cellulose fiber. [0005] The purpose of the present inve...
