PLA fiber is polylactide fiber. It is corn, wheat, sugar beet and other starch-containing agricultural products as raw materials. After fermentation to produce lactic acid, it is made by polycondensation and melt spinning. Polylactide fiber is a raw material for planting, Easy to grow, synthetic fibers that are naturally degradable in nature.

The raw material for the production of PLA fiber is made from corn starch, so this fiber is also called corn fiber and can be made by glucose fermentation using sugar beets or grains to reduce the cost of preparing lactic acid polymers. High molecular weight polylactic acid can be obtained by chemical polymerization of a lactic acid cyclized dimer or direct polymerization of lactic acid. Products obtained from polylactic acid as a raw material have good biocompatibility and bioabsorbability as well as bacteriostasis and flame retardancy, and PLA has the best heat resistance in a degradable thermoplastic polymer material.

PLA fiber can be decomposed into carbon dioxide and water by microorganisms in the soil or seawater. When it is burned, it will not emit poisonous gas and will not cause pollution. It is a sustainable development of ecological fiber. The fabric fabric has good hand feeling, drape, anti-ultraviolet radiation, low flammability and excellent processing performance, and is suitable for various fashion, casual wear, sporting goods and sanitary articles, and has a wide application prospect.
