With the outbreak of the COVID-19 epidemic, mouth purchase has become an indispensable item in people’s life. However, due to the extensive use and disposal of oral waste, it has led to the accumulation of oral garbage, causing a certain degree of pressure on the environment. Therefore, studying the biodegradability of mask materials is particularly important.
At present, the main material used for masks is non-woven fabric. Non woven fabric is a material mainly composed of fibers, which has good breathability, filtration, and flexibility, and is relatively inexpensive. Therefore, it is widely used in oral production. However, due to the fact that non-woven fabric materials are usually made of synthetic materials such as polypropylene, their biodegradability is very limited.
In response to this issue, researchers have begun to study the biodegradability of non woven fabric materials for masks. At present, some research results have made certain progress.
Natural fibers
Firstly, some researchers have attempted to use natural fibers instead of synthetic materials to produce non-woven masks. For example, non-woven fabrics made from natural fibers such as wood pulp fibers can improve the biodegradability of mask materials to a certain extent. Wood pulp fibers have good degradation properties and can be decomposed into carbon dioxide and water through the action of microorganisms, thereby reducing their impact on the environment.
Biodegradable additives
Secondly, some researchers have attempted to add biodegradable additives to improve the biodegradability of non-woven mask materials. Biodegradable additives are generally composed of biocatalysts such as microorganisms and enzymes, which can accelerate the degradation process of oral materials. By adding an appropriate amount of biodegradable additives, the degradation rate of non-woven fabrics can be accelerated to a certain extent, reducing their pollution to the environment.
Improve the structure and preparation process of non-woven fabrics
In addition, by changing the structure and preparation process of non-woven fabrics, the biodegradability of mask materials can also be improved. For example, researchers can adjust the fiber hierarchy of non-woven fabrics to be looser, increasing their surface area and opportunities for contact with microorganisms, thereby promoting material degradation. In addition, using biodegradable polymer materials to prepare non-woven fabrics can also improve the biodegradability of mask materials to a certain extent.
Conclusion
Overall, the research on the biodegradability of non-woven mask materials is still in its early stages, but some preliminary progress has been made. Future research can continue to explore the use of natural fibers, the addition of biodegradable additives, and changes in material structure and preparation processes to improve the biodegradability of oral non-woven fabric materials, thereby reducing the impact of oral waste on the environment.
