Abstract: front page image
(EN)[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.
(FR)L'objectif de cette invention est de fournir un objet moulé par injection, contenant des matières d'origine végétale comme constituants principaux, thermorésistant et présentant une grande vitesse de cristallisation. A cet effet, ledit objet moulé par injection est obtenu à partir d'une composition de résine comprenant (A) une résine d'acide lactique et (B) des fibres naturelles composées de 40 à 60 % en masse de cellulose et de 10 à 30 % en masse de lignine, le rapport résine d'acide lactique (A) sur fibres naturelles (B) étant compris entre 99/1 et 70/30 en masse et la résine d'acide lactique (A) présentant un rapport acide lactique L/acide lactique D compris entre 100/0 et 97/3 ou entre 0/100 et 3/97.
(JA) 【課題】植物由来原料を主成分とし、耐熱性を有し、結晶化速度の早い射出成形体を提供すること。  【解決手段】本発明の射出成形体は、(A)乳酸系樹脂、及び、(B)セルロース40質量%~60質量%とリグニン10質量%~30質量%とを含有する天然繊維、を含む樹脂組成物であって、(A)乳酸系樹脂と(B)天然繊維とを質量比で99:1~70:30の割合で含有し、かつ、(A)乳酸系樹脂が、L乳酸:D乳酸=100:0~97:3、又は、L乳酸:D乳酸=0:100~3:97である樹脂組成物を用いてなる。
