Problems solved by technology

Although disposable masks are easy to use, they also bring problems such as waste and environmental pollution. Because most of the masks in the prior art are made of polymers, they are not degradable in themselves and will have a certain impact on the environment. It is a one-time use, and the consumption is huge, which not only leads to environmental pressure, but also brings pressure on the production capacity of masks

Abstract

The invention provides a polylactic acid fiber reusable protective mask and a preparation method of the protective mask. The protective mask has the advantages of being capable of being repeatedly used and cyclically degraded, low in pollution and the like. According to the protective mask, a surface layer, an inner layer and a framework layer are fixedly connected in a fixing band component manner; raw materials and various parameters are reasonably selected; and the framework layer, the surface layer and the inner layer of the mask are connected together in a replaceable mode. A plurality ofsurface layers and inner layers with different function types can be designed; a plurality of different colors or patterns can be designed on the surface layer; and a wearer can select different masksurface layer or inner layer types according to needs, the defect that in the prior art, a mask needs to be discarded after being used once is overcome, the production line of mask products is greatly widened, consumers have a larger selection range, and the market share of the products can be increased.

Description

technical field [0001] The invention relates to the technical field of protective materials, in particular to a polylactic acid fiber reusable protective mask and a preparation method thereof. Background technique [0002] Air pollution is the pollution of the atmosphere caused by substances that are harmful to human health and the surrounding environment. These substances may be gases, solid or liquid suspensions, etc. Among them, suspended matter is usually distinguished by particle size. Particles with an aerodynamic diameter (hereinafter referred to as diameter) less than or equal to 10 microns are called inhalable particulate matter (PM10); particles with a diameter less than or equal to 2.5 microns are called fine particles (PM10). PM2.5). The above-mentioned particles can stay in the atmosphere for a long time, and can enter the body with breathing, accumulate in the trachea or lungs, and affect health. [0003] Virus particles, on the other hand, are very small, t...
