Abstract
A manufacturing method of a resin article having a plurality of filamentous projections that are formed in a contact surface of a resin article body may include a thrusting step to thrust acute-angled leading edges of plate-shaped metal parts into the contact surface of the resin article body, a heating step to heat the plate-shaped metal parts before or during the thrusting step, and a pulling out step to pull out the plate-shaped metal parts in a condition in which portions of the resin material of the resin article body is melted around the leading edges of the plate-shaped metal parts and in which melted resin portions are formed on unmelted portions of the resin material of the resin article body.
Claims5
A manufacturing method of a resin article having a plurality of filamentous projections that are formed on a contact surface of a resin article body such that the contact surface can adhere to a fibrous article, comprising:
- a thrusting step to thrust acute-angled leading edges of plate-shaped metal parts into the contact surface of the resin article body;
- a heating step to heat the plate-shaped metal parts to a temperature greater than a melting temperature of a resin material of the resin article body before or during the thrusting step;
- and
- a pulling out step to pull out the plate-shaped metal parts from the contact surface of the resin article body in a condition in which portions of the resin material of the resin article body around the leading edges of the plate-shaped metal parts are melted into melted resin portions while remaining portions of the resin material of the resin article body are not melted,
- wherein in the pulling out step, the melted resin portions stuck to the leading edges of the plate-shaped metal parts are drawn from the melted resin portions of the resin article body and extended into filaments, so as to be formed into the projections.
