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 the direct polymerization of lactic acid. Products made from PLA have good biocompatibility, biodegradability, antibacterial properties, and flame retardancy, and they exhibit good thermal resistance among biodegradable 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 offer high thermal and mechanical strength, and can be spun using conventional processing techniques without specialized equipment. The raw materials for PLA production are abundant, such as beets and corn, and can be continuously cultivated. By not using petroleum or wood, PLA helps conserve limited resources of these materials. The raw material for PLA is lactic acid, which includes -hydroxypropionic acid and 2-hydroxypropionic acid. Due to an asymmetric carbon atom in the lactic acid molecule, there are two enantiomers: d-type (dextro旋) and L-type (levorotatory). A mixture of equal amounts of L-lactic acid and d-lactic acid, known as dL-lactic acid, is optically inactive. Fibrous PLA is produced from L-lactic acid monomers. The industrial production of L-lactic acid mainly involves microbial fermentation and chemical synthesis methods.
