A product made from polylactic acid, which has good biocompatibility and absorbability, as well as bacteriostasis, flame retardancy, and heat resistance, and does not require special equipment and operating techniques. The processing technology can be used for spinning. Because PLA has good heat resistance, water diffusibility, and good drape, it can be made into filaments, short, monofilaments, and non-woven fabrics. In the field of clothing, it can be made into sportswear, and outerwear, while in the construction field, it can be used for nets, sandbags, and fishing nets as well as medical supplies, food packaging, and more. In recent years, cutting-edge domestic eco-friendly brands have focused on clothing design made from bio-based fabrics such as PLA.
