Nonwoven fabric for protective clothing and preparation method of non-woven fabric

Abstract

The invention relates to the technical field of non-woven fabrics, and provides a non-woven fabric for protective clothing and a preparation method of the non-woven fabric. The non-woven fabric comprises a non-woven fabric substrate, and the non-woven fabric substrate can be applied to the protective clothing after being treated by microcapsule finishing liquid, wherein the microcapsule finishingliquid is prepared from the following raw material in parts by weight: 35 to 60 parts of microcapsule emulsion, 6 to 12 parts of cross-linking agent, 2 to 4 parts of carboxymethyl cellulose and 1.5 to2.5 parts of fatty alcohol-polyoxyethylene ether; the microcapsule emulsion is prepared by taking chitosan and sodium alginate as wall materials and xylitol, N-ethyl-L-menthyl formamide and ammoniumnitrate as core materials by using a complex coacervation method, and the non-woven fabric substrate treated by the microcapsule finishing liquid solves the problems that in the prior art, the medicalprotective clothing non-woven fabric is single in function, a cool feeling cannot be generated, and stuffiness and discomfort are easily caused when a large amount of sweat is sweated.

Description

technical field

[0001] The invention relates to the technical field of nonwoven fabrics, in particular to a nonwoven fabric for protective clothing and a preparation method thereof. Background technique

[0002] Non-woven fabrics, also known as non-woven fabrics, are made by directional or random arrangement of short textile fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. They are flexible, light, non-toxic and non-toxic. Exciting, cheap, recyclable and so on. Non-woven fabrics have a wide range of uses and can be used in medical and health, home decoration, clothing, industry, agriculture and other fields. Among them, non-woven fabrics for medical and hygiene include disposable masks, protective clothing, surgical gowns, isolation gowns, lab coats, nurses, etc. Caps, surgical caps, doctor caps, surgical kits, maternity kits, first aid kits, and other disposable medical consumables series. Compared with t...
