|Polylactic acid fiber (PLA) is produced from corn starch. Therefore, this fiber is also called corn fiber, and can be produced by glucose fermentation using beet or grain to reduce the cost of preparing a lactic acid polymer. A high molecular weight polylactic acid can be obtained by chemical polymerization of a lactic acid cyclized dimer or direct polymerization of lactic acid. The product obtained from polylactic acid has good biocompatibility and bioabsorbability, as well as bacteriostasis and flame retardancy, and PLA has the best heat resistance in the degradable thermoplastic polymer material.|
PLA fiber has physical properties similar to those of PET fiber (ie, polyester fiber), not only has high crystallinity, but also has the same transparency; and because of its high crystallinity and high degree of orientation, it has high heat resistance and high Strength, and without special equipment and operating processes, can be spun using conventional processing techniques.
