The facial mask base fabric is prepared by the following methods: 1) taking wheat straw and cutting it, soaking it in water, then taking out and extruding and dehydrating to obtain wheat straw scraps; 2) cutting the wheat straw into pieces The material is steam-exploded to obtain an explosive fiber material; 3) the obtained explosive fiber material is washed with water to obtain a water-washed fiber material; 4) the washed fiber material is combed into a net, spunlace reinforced and dried to obtain a non-woven base material; 5) in the non-woven The ethanol solution of α-bisabolol is evenly sprayed on the surface of the substrate, and the ethanol is dried to remove the ethanol to obtain the Shumin base material; 6) The Shumin base material is immersed in the aqueous solution of chitosan acetic acid, degassed under negative pressure, and the excess liquid is squeezed out after being taken out and dried. have to. The obtained mask base fabric has appropriate mechanical properties, good liquid holding capacity and air permeability, good biocompatibility and antibacterial properties, no adverse reaction to human skin during use, and good use effect; The degradation rate in the environment is fast, and it is environmentally friendly.

A kind of mask lining cloth and its manufacturing method
ActiveCN106480604BImprove breathabilityDoes not affect normal breathingPhysical treatmentGarmentsParticulatesFiltration
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.
