Poly乳酸 fiber (PLA) is produced from lactic acid, which is derived from corn starch, hence the fiber is also known as corn fiber. It can be fermented from beets or grains to reduce the cost of producing lactic acid polymers. High molecular weight PLA can be obtained through the chemical polymerization of lactide or direct polymerization of lactic acid. Products made from PLA have good biocompatibility and biodegradability, as well as antibacterial and flame-retardant properties. In degradable thermoplastic polymers, PLA exhibits good heat resistance. PLA fibers have similar physical properties to PET fibers (i.e., polyester fibers), with high crystallinity and transparency. Due to their high crystallinity and orientation, they also possess high thermal resistance and strength, and can be spun using conventional processing techniques without special equipment or processes. The raw materials for PLA production are abundant, such as beets and corn, and these can be continuously cultivated. As it does not use oil or wood, this helps protect limited resources of oil and wood. The raw material for PLA is lactic acid, which includes -hydroxypropionic acid and 2-hydroxypropionic acid. Due to the presence of an asymmetric carbon atom in the lactic acid molecule, there are two enantiomers: d- (right-handed) and L- (left-handed). DL-lactic acid, which is a mixture of equal amounts of L- and d-lactic acid, does not have optical activity. Fibrous PLA is made from L-lactic acid monomers. The industrial production of L-lactic acid mainly involves microbial fermentation and chemical synthesis methods.
