Polyactic Acid (PLA) fibers are derived from lactic acid, which is produced from corn starch, hence the name corn fiber. They can also 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. PLA exhibits good thermal resistance among degradable thermoplastic polymers. PLA fibers share similar physical properties with PET fibers (i.e., polyester fibers), including high crystallinity and transparency. Due to their high crystallinity and orientation, they also offer high thermal and mechanical strength, and can be spun using conventional processing techniques without special equipment. The raw materials for PLA production are abundant, such as beets and corn, which can be continuously cultivated. By not using petroleum or wood, PLA helps preserve limited resources of these materials. The raw material for PLA is lactic acid, which includes -hydroxypropionic acid and 2-hydroxypropionic acid. Lactic acid molecules contain an asymmetric carbon atom, resulting in two enantiomers: d-type (dextro旋光) and L-type (levorotatory). A mixture of equal amounts of L-lactic acid and d-lactic acid forms dl-lactic acid, which is optically inactive. The monomer for fiber-forming PLA is L-lactic acid. Industrial production of L-lactic acid mainly involves microbial fermentation and chemical synthesis methods.
