    摘要： The invention provides a method for manufacturing a molded woody article, which includes compression molding a base material containing wood fibers, polylactic acid fibers and an inorganic filler at a temperature not less than a melting point of the polylactic acid fibers, and maintaining the molded base material at a temperature close to a crystallization temperature of the polylactic acid fibers for a desired period of time, thereby crystallizing the polylactic acid fibers. In the molding step, the base material is entirely deformed and molded into a desired shape while the polylactic acid fibers are melted, and in the crystallizing step, the polylactic acid fibers are solidified, thereby producing the molded article. In the crystallizing step, polylactic acid crystallizes rapidly and reliably utilizing the inorganic filler as a crystal nucleating agent.

The method includes compression molding a base material containing wood fibers, polylactic acid fibers and an inorganic filler at a temperature not less than a melting point of said polylactic acid fibers, and maintaining said molded base material at a temperature close to a crystallization temperature of said polylactic acid fibers for a desired period of time, thereby crystallizing the polylactic acid fibers. In the molding step, the base material is entirely deformed and molded into a desired shape while the polylactic acid fibers are melted, and in the crystallizing step, the polylactic acid fibers are solidified, thereby producing the molded article. In the crystallizing step, polylactic acid crystallizes rapidly and reliably utilizing the inorganic filler as a crystal nucleating agent. Polylactic acid crystallizes from portions contacting the wood fibers.

    摘要： The object of the present invention is to provide a monofilament which has sufficient mechanical strength to be practically used also as a string for rackets and which is excellent in workability. Disclosed is a monofilament which is formed by extruding a material prepared by blending mainly a polylactic acid type polymer (A) and an aliphatic polyester (B) other than polylactic acid, and drawing the extruded material. This could be used as a racket string which has a tenacity-elongation curve similar to that of natural gut and is excellent in water resistance and heat resistance.
