Chitin and derivative antibacterial cloth thereof as well as preparation method and application of chitin and derivative antibacterial cloth

Abstract

The invention discloses chitin and derivative antibacterial cloth and a preparation method and application thereof.The preparation method comprises the steps that in the warping process that cotton yarn passes through a raddle, flowing water flow is adopted to continuously spray reed holes, through which the cotton yarn passes, in the raddle, and the cotton yarn and cotton fibers, blocked and screened out by the raddle, on the cotton yarn are wetted; collecting the wetted cotton fibers, wherein the cotton fibers comprise short fibers and flyings; mixing the wetted cotton fibers and chitin and derivative fibers thereof in water, then outputting the mixture to a dehydration area in a planar form, and after dehydration, carrying out spunlace net formation and drying to prepare chitin and derivative antibacterial cloth thereof; the chitin and derivative antibacterial cloth prepared by the method not only has a better antibacterial function, but also has the properties of lightness, thinness, softness, flexibility and the like, and is suitable for preparing products such as diapers and sanitary napkins.

Description

technical field [0001] The invention belongs to the field of antibacterial fibers, in particular to products that can be applied to diapers, sanitary napkins and other products that require high lightness, softness, flexibility, and antibacterial safety, and in particular to a chitin and its derivative antibacterial cloth And its preparation method and application. Background technique [0002] Chitin has certain casting and filamentation properties, and is a good fiber-forming material. With proper spinning conditions, chitin fibers with high strength and elongation can be produced through conventional wet spinning processes. Chitosan and its derivatives can generally be made into chitosan fiber after chitin is treated with concentrated alkali to remove acetyl groups, so it is also called deacetylated chitin fiber or chitosan fiber. Due to the presence of a large number of hydroxyl groups and positively charged amino groups in the macromolecular structure of chitin and chi...

AI Technical Summary

Problems solved by technology

[0003] Therefore, at present, chitin fiber and its derivative chitosan fiber are widely used in antibacterial textiles. In addition, for products such as diapers and sanitary napkins that require high lightness, softness, flexibility, and antibacterial safety, although chitin fiber and its derivative product chitosan fiber have relatively high Good antibacterial performance, but the actual products are difficult to take into account lightness, softness, flexibility and other properties, which further limits the application of chitin fiber and its derivative chitosan fiber
