Polylactic acid (PLA
) is a new type of biodegradable material, which is mainly made of starch raw materials proposed by renewable plant resources (such as corn), with good biodegradability and biocompatibility. Packing, fiber, medical is three popular application directions.
First, about PLA fiber
As a thermoplastic fibrous resin, the fibrous polylactic acid PLA
is used in particulate form for extruding it into a mechanically stretched short fiber; it has excellent coloring, mechanical properties and Good physical properties, adapt to a variety of printing methods, which are used in a variety of occasions.
The PLA fiber fuses the advantages of natural fibers and chemical synthetic fibers, while combining biodegradation characteristics, with better hydraulic, sleek, gas permeability, natural antibacterial and weak acidity, anti-UV Features. As the only biological degradable plastic having excellent antibacterial and antiwei characteristics, it can be widely used in terminal products such as clothing, home textiles, medical and health supplies, and give full play to the efficacy of green, environmentally friendly and low carbon.
In 2020, due to the emergence of new champions, the non-woven industry has ushered in extremely busy years. A large number of disposable protection and cleaning supplies were put into the anti-vlotenion front line. After use, they quickly become the burden of nature with irreparable "medical garbage".
According to CCTV Financial report, 2020, a total of approximately 52 billion masks were produced in 2020, of which at least 1560 million were influenced by the ocean for processing. The mask constantly absorbs toxic substances in the sea, marine creatures When you eat the jellyfish, you may block the esophagus and starve, or you may be slow to poison, and these masks are degraded for more than 450 years.
This also caused the thinking and worry of all walks of life. Therefore, in the context of global ban, biodegradable materials, such as polylactic acid, etc., the application of the non-woven industry has been more concerned
