INJECTION-MOLDED OBJECT, PROCESS FOR PRODUCING THE SAME, AND PELLET FOR USE FOR INJECTION-MOLDED OBJECT

摘要

[PROBLEMS] To provide an injection-molded object which comprises plant-derived materials as major components and has heat resistance and a high rate of crystallization. [MEANS FOR SOLVING PROBLMES] The injection-molded object is obtained from a resin composition which comprises (A) a lactic acid resin and (B) natural fibers comprising 40 to 60% by mass cellulose and 10 to 30% by mass lignin, wherein the proportion of the lactic acid resin (A) to the natural fibers (B) is from 99/1 to 70/30 by mass and the lactic acid resin (A) has an (L-lactic acid):(D-lactic acid) ratio of from 100/0 to 97/3 or from 0/100 to 3/97.
