Abstract: A polypropylene composite resin composition and a molded article including the polypropylene composite resin composition are disclosed. In certain examples, the polypropylene composite resin composition includes an improved elongation and impact strength. The polypropylene composite resin composition may include a first polypropylene copolymer having a melt flow index in a range of 30 g/10 min to 150 g/10 min (230° C., 2.16 kg), a second polypropylene copolymer having a melt flow index in a range of 1 g/10 min to 20 g/10 min (230° C., 2.16 kg), an impact modifier having a Mooney viscosity (ML1+4, 125° C.) in a range of 10 to 70, a dye, and an additive in appropriate amounts.

Abstract: Disclosed is a method of manufacturing bamboo toothbrush and a toothbrush manufactured thereby. According to the method of manufacturing bamboo toothbrush of a detailed embodiment of the present invention and a toothbrush manufactured by the method, it is possible to improve strength, surface roughness, and moisture resistance of a bamboo and adjust the color of the bamboo using hot pressing. Further, since sanding and polishing and separate coating and drying are not performed, the process time is reduced, whereby the manufacturing cost can be reduced.
