Problems solved by technology

[0004] The present invention is to overcome the relatively hard hand feeling and poor softness of protective clothing materials in the prior art; The protective effect can only lead to the problem of poor wearing comfort. A protective clothing material based on spunlace non-woven material and its preparation method are provided. Protective clothing is made of non-woven fabrics and materials composited with PTFE films. Spunlace non-woven fabrics do not have any rolling points, are soft to the touch and have good air permeability. The protective clothing made by compounding with breathable PTFE film can have both protection and comfort

Abstract

The invention discloses a protective clothing material based on a spunlace non-woven material and a preparation method thereof. An outer protective layer, an adhesive layer and a spunlace non-woven fabric layer are sequentially attached, the spunlace non-woven fabric layer is subjected to water-repellent, oil-repellent, blood-resistant and alcohol-resistant four-antibody finishing, the outer protective layer is a PTFE film, and the spunlace non-woven fabric layer is made of bamboo pulp fibers and polyester fibers. The preparation method comprises the following steps: preparing the spunlace non-woven fabric layer, namely mixing bamboo pulp fibers and polyester fibers in proportion, carding, lapping, drafting, performing high-pressure spunlace, performing four-antibody finishing, drying at high temperature, sterilizing, slitting and rolling to obtain the spunlace non-woven fabric layer; wherein the surface of the spunlace non-woven fabric layer is coated with an adhesive, then the spunlace non-woven fabric layer is covered with a PTFE film, and the final material is obtained through multi-stage tentering shaping after pressurization compounding of a heating roller. The protective clothing material is free of any rolling points, soft in hand feeling, good in air permeability, comfortable to wear and good in protective property.

Description

Technical field [0001] The invention relates to the technical field of medical materials, in particular to a protective clothing material based on a spunlace non-woven material and a preparation method thereof. Background technique [0002] Medical protective clothing refers to the protective clothing used by medical personnel and people entering a specific medical and health area. Its function is to isolate germs, harmful ultrafine dust, acid-base solutions, electromagnetic radiation, etc., to ensure the safety of personnel. Most of the current protective clothing is made of SMS or SMMS spunbonded and meltblown non-woven material composite PE film or other outer protective layer, or directly spunbonded non-woven fabric is made of PU film or TPU film and other outer protective layer. For example, "a kind of protective clothing" disclosed in Chinese patent documents, its announcement number CN109105970A, is prepared from functional fabrics according to conventional protective clot...
