Problems solved by technology

[0004] The present invention is to overcome the relatively hard hand feeling and poor softness of medical mask materials in the prior art; The protective effect can only lead to the problem of poor wearing comfort. A medical mask material based on spunlace non-woven material and its preparation method are provided. The high-performance spunlace non-woven fabric and the material composited with PTFE film are used to make medical masks. The spunlace non-woven fabric has no rolling point, soft hand feeling and good air permeability. The medical mask made by compounding the PTFE film with good protection and air permeability can have both protection and comfort

Abstract

The invention discloses a medical mask material based on a spunlace non-woven material and a preparation method of the medical mask material. The medical mask material comprises an outer protective layer, an adhesive layer and a spunlace non-woven fabric layer 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 antibacterial 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; coating the surface of the spunlace non-woven fabric layer with the adhesive, then covering the spunlace non-woven fabric layer with the PTFE film, and obtaining the final material through multi-stage tentering shaping after pressurization compounding of a heating roller. The medical mask material is free of any rolling point, soft in hand feeling, good in air permeability, comfortable to wear and good in protection performance.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical mask material based on a spunlace nonwoven material and a preparation method thereof. Background technique [0002] Medical mask is a kind of medical protective equipment, its function is to resist liquid, filter particles and bacteria, etc., to ensure the safety of personnel. Most of the current medical masks are made of SMS or SMMS spunbond plus meltblown nonwoven material composite PE film and other outer protective layers, or directly spunbonded nonwoven composite with PU film or TPU film and other outer protective layers. For example, a "dust-proof and antibacterial medical mask" disclosed in the Chinese patent literature has a notification number of CN203152562U, and the outer layer is a spunbond non-woven fabric layer, an anion nanometer non-woven fabric layer or a silver ion fiber non-woven fabric layer. The middle layer is a melt blown non-woven fabr...
