From these, the simple materials that will be the units of the fiber polymer are obtained. These units must have reactive groups at both ends; in polymerization, these groups join to form very long chain molecules with fiber-forming properties. Since the beginning of the 21st century, synthetic fibers (for example, poly lactic acid PLA) are being formed also with units made from renewable materials, such as corn starch. ;2.3.3 Synthetic Fibers(合成纤维) ;2.3.3 Synthetic Fibers(合成纤维) ;2.3.3 Sy
