A kind of mask lining cloth and its manufacturing method

Abstract

The invention discloses gauze mask lining cloth. The gauze mask lining cloth comprises 80.0-98.0 wt% of polypropylene, 0.1-20.0 wt% of nylon and 0.1-2.0 wt% of electrostatic auxiliaries. A method for manufacturing the gauze mask lining cloth includes steps of (1), preparing materials, to be more specific, feeding polypropylene granules and electrostatic auxiliary granules in formulas into a mixer and sufficiently mixing the polypropylene granules and the electrostatic auxiliary granules with one another to obtain mixtures; (2), melting the uniformly stirred mixtures; (3), spinning the molten mixtures to obtain polypropylene fibers; (4), mixing the polypropylene fibers and nylon fibers with one another to obtain mixed fibers; (4), carding the mixed fibers generated at the previous step to obtain fiber networks; (5), carrying out needling and adding static electricity, to be more specific, carrying out needling treatment on the fiber networks obtained at the previous step to turn the fiber networks into gauze mask lining cloth and adding the static electricity to the gauze mask lining cloth; (6), rolling and packaging the gauze mask lining cloth. The gauze mask lining cloth and the method have the advantages that the gauze mask lining cloth manufactured by the aid of the method is high in breathability as compared with other traditional non-woven fabrics and is free of influence on normal respiration of users; PM 2.5 (particulate matter 2.5) adsorption filtration effects can reach 85%, and the gauze mask lining cloth is high in tension resistance and extremely low in wind resistance.

Description

technical field [0001] The invention belongs to the field of sanitation protection, in particular to a lining cloth for a dust-proof mask that can effectively filter PM 2.5. Background technique [0002] At present, there are many masks on the market that remove PM2.5, which are just ordinary cotton or non-woven masks, and better masks will add activated carbon. Cotton and non-woven masks cannot achieve the purpose of filtering PM2.5, and masks added with activated carbon will cause breathing difficulties, affect normal breathing and cause discomfort. Moreover, the adsorption effect of these masks on dust, virus and bacteria is not obvious. Contents of the invention [0003] The object of the present invention is to provide a kind of mask lining cloth that can solve the above problems and manufacture method thereof. [0004] A mask lining cloth, comprising 80.0-98.0wt% polypropylene fiber and 0.1-20.0wt% nylon. [0005] In particular, in order to enhance the adsorption ...
