<p>Provided is a manufacturing method for injection-molded articles, comprising subjecting a resin composition for use in injection molding, which contains a polylactic acid resin and PET fibers with a lactic acid component content of 50% by weight or more, and is compounded at a compounding temperature of 230°C or lower, to injection molding at an injection molding temperature of 190 to 230°C to obtain a molded article of high strength in which voids around the PET fibers are 50% or less on the PET fibers in sectional area in the article's sections, and the PET fibers within the article are not deteriorated. The molded article has a higher strength than conventional, and is applicable as a constituent part for larger products with heavier weights, such as copying machines and printers.</p> |
