Abstract

Disclosed is an upholstery material (10) that comprises a facing material (11), a polyurethane foam (12) adhered to the inward side thereof, and a nonwoven cloth (13) adhered to the inward side thereof, and which has a water pressure resistance of 450 mmH2O or greater, preferably 500 mmH2O or greater, and more preferably 550 mmH2O or greater; has an air permeability of 0.1 to 20 cc / cm2 / s, and preferably 5 to 15 cc / cm2 / s; has an average pore size of 0.1 to 20 µm, and preferably 5 to 15 µm.

Description

technical field [0001] The present invention relates to a skin material for integral skin foam molding, which is a material having both leakage resistance and air permeability, wherein liquid foaming resin is injected into the skin material after three-dimensional sewing and the foam Bubbles, in the case of obtaining a molded body integrated with the skin material, it is possible to prevent the seepage caused by the penetration of the liquid foaming resin, and at the same time, it is possible to remove the bubbles generated with the foaming injection to prevent the generation of voids. , the skin material is particularly suitable for the molding of headrests, armrests and control boxes (console boxes) for automobiles. Background technique [0002] One of the products manufactured by the integral skin foaming molding method is headrests and armrests for automobiles. The molding method is to sew the skin material three-dimensionally, inject liquid foaming resin into the inside...
