Title:
PROCESS FOR PRODUCTION OF ALIPHATIC POLYESTER COMPOSITION, PULP AND CELLULOSIC FIBER TO BE USED THEREIN, AND PROCESS FOR MICROFIBRILLATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2005/003450
Kind Code:
A1
Abstract:
A fiber/biodegradable resin composite material having high rigidity and high strength can be produced by dispersing a fiber component in a resin component finely and uniformly by a general-purpose kneading means without pretreatment of the resin component. Namely, such a composite material can be produced by melt-kneading together 1 to 99.9 parts by weight of a resin component consisting of 1 to 100 wt% of (A) an aliphatic polyester and 99 to 0 wt% of (B) polylactic acid and 99 to 0.1 parts by weight of a fiber component consisting of (C) pretreated pulp and/or cellulosic fiber with scratches on the outer layers of primary and secondary walls in the presence of (D) a swelling agent capable of swelling the noncrystalline region of cellulose. During the melt kneading, the fiber component is microfibrillated through opening and dispersed in the resin component uniformly and finely.
