And the traditional disposable mask is not degradable and environment-friendly, and contributes to the increasingly serious plastic pollution.
Patent No. CN 206482066U 3 discloses a disposable paper gauze mask of environment-friendly, and the gauze mask piece that adopts the paper material preparation has good environmental protection performance, can decompose fast under natural condition, and the paper gauze mask is more ideal for other kinds of gauze mask environmental protection effect.
Patent No. CN 204561022U 3 discloses an environment-friendly silk-faced haze-preventing mask, wherein cross-lapping silk spunlace non-woven fabrics are used as an inner mask layer 1, are close to skin, have no stimulation to skin, are soft and comfortable, are warm in winter and cool in summer, can resist ultraviolet rays, and are acid-resistant and alkali-resistant; the silk spunlace non-woven fabric is internally of a porous structure, contains partial air, has the functions of moisture absorption and moisture desorption, and is not easy to generate static electricity and dust collection during friction.
In the above patent publications, the mask sheet made of paper material or the cross-lapped spunlace nonwoven fabric is used as the inner mask layer, although the comfort and environmental protection can be improved to some extent, the effect is not obvious. The mask piece made of the paper material is not strong enough and is easy to damage, and the silk spunlace non-woven fabric is made of the silk spunlace non-woven fabric, so that the production cost of the mask can be increased, and the mask piece does not have the functions of skin-friendly bacteriostasis, good air permeability, no sensitization and the like of a polylactic acid new material.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a polylactic acid material biodegradable environment-friendly functional protective mask, which solves the problems that the traditional disposable protective mask uses petroleum-based chemical fiber non-woven fabrics and PP melt-blown fabrics, has sensitization to skin, poor air permeability, non-degradability and no environmental protection.
