MANUFACTURING METHOD OF COLORED POLYLACTIC ACID RESIN |
摘要 |
Disclosed is a technique of providing color to a polylactic acid resin which is promising as a plant-derived material for automotive interior/exterior parts. When a polylactic acid material is used as a covering fiber material of an automotive interior part, coloring is necessary for harmonization with other parts in the car. According to the disclosed technique, color is provided to a polylactic acid resin using a combination of a catalyst and an initiator when it is polymerized from lactide. The disclosed method is time-saving and economical since a colored resin can be polymerized and thus the complicated process of dyeing a white resin using a disperse dye and washing and drying the same can be avoided.
