Problems solved by technology

[0003] However, the mechanical properties of the traditional silk protein fiber itself are not good. As a clothing fabric, it may be easily damaged when scrubbing, reducing its service life. In addition, silk protein itself does not have good antibacterial properties. If its properties are modified to prepare Underwear products that can inhibit bacteria and antibacterial are also products with market value at this stage

preparation example Construction

[0038]The preparation method of the cellulose nanocrystal dispersion is as follows: the first step: weigh 10 parts of cellulose pulp and pulverize it under mechanical stirring at 300 rpm; the second step: add the pulverized pulp to 200-300 ml In concentrated sulfuric acid solution with a mass fraction of 65%, react at 40-100°C for 30-90 minutes; Step 3: After the reaction, add the mixed reaction solution to 10 times the volume of pure water, and remove the supernatant after the precipitation is complete liquid; the fourth step: centrifuge the lower layer of turbid liquid at 9000-12000rpm, gradually wash and centrifuge to neutrality; the fifth step: the upper white liquid obtained by centrifugation is the cellulose nanocrystal dispersion liquid, and ultrasonically disperse it for 10 minutes. The obtained cellulose nanocrystal dispersion was stored at 5°C for future use.

Abstract

The invention belongs to the technical field of spinning, and particularly relates to a silk protein-containing fiber and a preparation method thereof. The invention provides the silk protein-containing fiber, and preparation raw materials of the fiber comprise chitosan, silk protein, nano cellulose and water-soluble cationic cellulose. According to the silk protein-containing fiber and the preparation method thereof, the chitosan is added on the top of the advantages of the silk protein fiber, and the antibacterial and bacteriostatic effect of the silk protein fiber is further enhanced by N<+> of the chitosan; and in addition, cellulose nanocrystals and the water-soluble cationic cellulose are added into the silk protein fiber, so that the mechanical property and the washing resistance performance of the fiber are enhanced, the existence significance of the fiber is increased, and the application prospect of the fiber is expanded.

Description

technical field [0001] The invention belongs to the technical field of textiles, and more specifically relates to a fibroin-containing fiber and a preparation method thereof. Background technique [0002] As a new type of functional fiber, silk protein fiber has attracted people's attention with its unique performance and unparalleled vitality. Silk protein fibers have good moisture absorption and release properties, because silk protein fibers are enriched with many amino groups (-NH 2 ) and amine groups (-CHNH) and other hydrophilic groups, and because of its porosity, it is easy for water molecules to diffuse, so it can absorb a certain amount of water or maintain a certain amount of water in water molecules. [0003] However, the mechanical properties of the traditional silk protein fiber itself are not good. As a clothing fabric, it may be easily damaged when scrubbing, reducing its service life. In addition, silk protein itself does not have good antibacterial propert...
