example 1

[0026] Carboxymethyl chitin fiber and cotton fiber are mixed according to the above method in a weight ratio of 10:90 to make a needle-punched nonwoven fabric. Antibacterial test results show that the reduction rate for Escherichia coli (8099) is 99.9%, the percentage reduction for Staphylococcus aureus (ATCC6538) is 99.9%, and the percentage reduction for Candida albicans (ATCC10231) is 97.4%.

example 2

[0028] Carboxymethyl chitin fiber and polyester are mixed according to the above method in a weight ratio of 50:50 to prepare a needle-punched nonwoven fabric. Antibacterial test results show that the reduction rate for Escherichia coli (8099) is 99.9%, the percentage reduction for Staphylococcus aureus (ATCC6538) is 99.9%, and the percentage reduction for Candida albicans (ATCC10231) is 98%.

example 3

[0030] Carboxymethyl chitin fiber and viscose fiber are mixed according to the above method in a weight ratio of 60:40 to make a needle-punched nonwoven fabric. Antibacterial test results show that the reduction rate for Escherichia coli (8099) is 99.9%, the percentage reduction for Staphylococcus aureus (ATCC6538) is 99.9%, and the percentage reduction for Candida albicans (ATCC10231) is 99.0%.

Abstract

A chitin nonwoven cloth is prepared by mixing 10-100 weight share of water soluble chitin fibre with 0-90 weight share of basic fibre. Its preparing process includes opening, feeding, flowing, lapping, needle punching, winding and packing. The prepared nonwoven cloth can be used to produce sanitary napkins, face cleaning film, etc.

Description

technical field [0001] The invention relates to an antibacterial and deodorant needle-punched cloth of chitin fiber, a preparation method and application thereof. Background technique [0002] With the change of consumption concept, people have updated requirements for textiles, so non-woven fabrics with health care effects are very popular. [0003] As we all know, chitin is the second type of high molecular compound after cellulose in nature, and it is generally extracted and purified from marine shrimp and crab shells. Since chitin is a positively charged natural nitrogen-containing polysaccharide polymer in structure, the chitin fiber spun through chemical processing also has a positive charge, which can make it negatively charged The charges of bacteria and other microorganisms are neutralized, so that the activity of bacteria is inhibited and inactivated, so as to achieve the functions of antibacterial, deodorizing and antipruritic. At the same time, when chitin fibe...
