Problems solved by technology

my country consumes a large amount of medical non-woven fabrics every year, but the current commercially available medical non-woven fabrics have relatively single functions, and there is a lack of a medical non-woven fabric that integrates antibacterial, radiation protection, flame retardant and antistatic functions.

Abstract

The invention provides an antibacterial flame-retardant nonwoven composite, comprising a first nonwoven layer, a base material layer and a second nonwoven layer sequentially from top to bottom; a first antibacterial layer and an anti-radiation layer are disposed sequentially between the first nonwoven layer and the base material layer, and a second antibacterial layer and a flame-retardant antistatic layer are disposed sequentially between the second nonwoven layer and the base material layer; the first antibacterial layer is a porous nano activated carbon silver-supported antibacterial agent coating 15-50 nm in particle size, and the second antibacterial layer is a bio-polypeptide antibacterial agent layer; the first and second nonwoven layers are made from polyadipic acid / butylene terephthalate, polypropylene and polycaprolactam through melt-blowing; the medical nonwoven composite prepared herein is antibacterial, anti-radiation, flame-retardant and antistatic and is mainly used in the field of medical use.

Description

technical field [0001] The invention belongs to the field of non-woven fabrics, and in particular relates to a medical antibacterial and flame-retardant non-woven fabric composite material and a preparation method thereof. Background technique [0002] Non-woven fabric (non-woven fabric) is a kind of fabric formed without spinning and weaving. It just orients or randomly arranges short textile fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical bonding. Reinforced by other methods. To put it simply: it is not interwoven and knit together by yarns one by one, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes , you will find that it is impossible to extract the thread ends one by one. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide applicatio...
