Polylactic acid is a new type of biodegradable material, which is mainly made of starch raw materials proposed by renewable plant resources (such as corn), and has good biodegradability and biocompatibility. Packaging, fiber, and medical are the three most popular application directions.
As a thermoplastic fiber-grade resin, fiber-grade PLA is in the form of pellets for extrusion into mechanically drawn short fibers using conventional fiber spinning and drawing equipment; it has excellent colorability, mechanical properties and good physical properties, it can adapt to various printing methods and be used in various occasions.
PLA fiber combines the advantages of natural fibers and chemical synthetic fibers, and at the same time has biodegradable properties, and has good drapability, smoothness, breathability, natural antibacterial properties, weak acidity, and UV resistance that reassure the skin Features. As the only biodegradable plastic with excellent antibacterial and anti-mildew properties, it can be widely used in end products such as clothing, home textiles, medical and sanitary products, and give full play to the green, environmental protection and low-carbon effects of polylactic acid fiber.
At present, the main products are polypropylene (PP) non-woven fabrics, which are non-degradable and do not meet the requirements of green environmental protection and sustainable development. Promoting the application of biodegradable materials in the field of non-woven fabrics will be the general trend. PLA non-woven fabric not only fully meets the safety and ease-of-use requirements of disposable protective products, but also endows the product with new green and environmental protection features. After use, it can be completely biodegraded within a few months under composting conditions. Not only will it not burden the environment, but it will also participate in the natural cycle.
1. Characteristics of PLA non-woven fabric
PLA non-woven fabric is moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, and recyclable.
2. Application field of PLA non-woven fabric
PLA non-woven fabrics can be used for disinfection wraps, masks, diapers, civilian wipes, wet wipes, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths; in addition, polylactic acid film cloth is a new bio-based material, Soft to the touch, strong adsorption, moisturizing, breathable, and antibacterial, it is a pure, safe, healthy, and skin-friendly high-quality material. It has many biological characteristics that other substrates cannot match, and is an ideal substrate for high-quality facial masks. Under the background of the new era, the PLA non-woven fabric industry will also undergo new changes. Environmental protection, low carbon and sustainable development will be the main theme for a long time.
