Fastening component and method for manufacturing the fastening component

摘要

A fastening component is a molded article of a mixture in which microfibrillated cellulose fibers are dispersed in a thermoplastic resin, wherein the thermoplastic resin has a melting point of between 150 and 200° C., and wherein when the total mass % of the thermoplastic resin and the cellulose fibers is set to be 100 mass %, the mass % of the cellulose fibers included in the mixture is greater than 20 mass % and less than 60 mass %. When the total mass % of the thermoplastic resin and the cellulose fibers is set to be 100%, the mass % of the cellulose fibers included in the mixture is preferably equal to or greater than 30 mass % and equal to or less than 50 mass %.

1. A fastening component that is a molded article of a mixture, the mixture comprising;
a thermoplastic polymer resin having a melting point of between 150 and 200° C., wherein the thermoplastic polymer resin comprises a polyamide; microfibrillated cellulose fibers dispersed in the thermoplastic polymer resin; and an inorganic pigment, wherein when the total mass % of the thermoplastic polymer resin and the cellulose fibers is set to be 100 mass %, the mass % of the cellulose fibers included in the mixture is greater than 35 mass % and less than 60 mass % and wherein the mixture melted at a temperature of 220° C. has a melt viscosity of equal to or less than 500 Pa/s at shear velocity of 12160 sec−1 and a melt viscosity of equal to or greater than 5000 Pa/s at shear velocity of 12.16 sec−1.
