内装材の製造方法
Document Type and Number:
Japanese Patent JP4154638
Kind Code:
B2
Abstract:
In a method of producing an interior trim material, a laminated structure is formed by laminating a skin material, a mat-like fiber structure, and a high-melting-point fiber sheet in this order. The mat-like fiber structure is prepared by blending thermoplastic fibers and inorganic fibers, and the high-melting-point fiber sheet is formed from fibers having a melting point higher than that of the thermoplastic fibers. At least the mat-like fiber structure is heated so that the thermoplastic fibers are melted. The laminated structure is then compressed under pressure by a hot press machine, and then expanded to restore at least part of the thickness thereof. The laminated structure thus expanded is then formed into a certain shape by a cold press machine, while the thermoplastic fibers of the mat-like fiber structure maintains plasticity.
