Abstract:
1. A method for manufacturing a molded woody article, comprising: compression molding a mat-shaped base material containing wood fibers, polylactic acid fibers made of polylactic acid having a crystallinity of 30% to 50% to a crystallization rate of 100%, and an inorganic filler at a temperature not less than a melting point of said polylactic acid fibers, thereby forming a flat plate-shaped base material; and maintaining said molded base material at a temperature close to a crystallization temperature of said polylactic acid fibers for a period of time that allows a crystallinity of 30% to 50% of the polylactic acid fibers, thereby crystallizing the polylactic acid fibers; wherein in the compression molding step, the base material is prepared such that a ratio of the wood fibers to the polylactic acid fibers is in a range of 7:3 to 5:5 by weight, and a ratio of the inorganic filler to the polylactic acid fibers is in a range of 0.1 to 5% by weight; and wherein the molded woody article has a density in a range of 0.5 g/cm
