Most of the main components of the masks on the market at present are polypropylene, which belongs to non-degradable plastics. Although the group standard of T/BJFX 0001-2020 reusable civil mask is released in 4 months in 2020, the generation of mask garbage can be inhibited to a certain extent, the plastic garbage of the civil mask cannot be thoroughly solved, and effective schemes and technologies for recycling the polypropylene with high melt index (about 90g/10min for non-woven fabrics and 1000g/10min for melt-blown barrier fabrics) are lacked.

PLA (polylactic acid) and PBAT (poly (lactic acid)) which are environment-friendly materials have the characteristics of reproducibility, biodegradability, biocompatibility, low carbon emission, low energy consumption and the like. The PLA linear thermoplastic biodegradable aliphatic polyester is a high polymer material which is prepared by taking starch extracted from annual plants such as corn, wheat, cassava and the like as an initial raw material, preparing high-purity lactic acid by a modern biological fermentation technology and performing a special polymerization reaction, so that the PLA linear thermoplastic biodegradable aliphatic polyester is a renewable substance. When the PLA product is buried in soil with higher humidity and temperature after being abandoned, the PLA product can show degradation signs within 6 months, and can be decomposed into CO under the action of microorganisms, water, acid and alkali along with the increase of the burying time ₂ And H ₂ O, which is then used as the starting material of starch under the action of sunlight photosynthesis, does not pollute the environment, and is a completely natural circulation type biodegradable material. More importantly, the prior synthesis process of the PLA basically takes the L-lactic acid as a monomer, and the L-lactic acid is a normal sugar metabolite in a human body, so that the PLA fiber has excellent biocompatibility in the human body. PLA can reduce CO compared to other petrochemical plastics ₂ Emission and energy consumption. This is certainly an excellent solution to the environmental problem caused by the current mask trash. PBAT belongs to thermoplastic biodegradable plastics, is a copolymer of butanediol adipate and butanediol terephthalate, has good ductility and elongation at break, good heat resistance and impact resistance, and excellent biodegradability.The biodegradation of PBAT depends mainly on its chemical structure and degradation environment, being almost completely biodegradable, some being degradable by fermentation by natural microorganisms, some being depolymerizable by breaking polymer chains by chemical hydrolysis and thermal degradation, and some being depolymerizable by microbial metabolism.
