<p>PURPOSE: To obtain an upholstery material having a moisture absorptivity and wear resistance without fading by arraying a polyurethane layer having a high porosity, color fastness and wear resistance, a foam laminate layer, and then a fiber layer having properties for absorbing and holding humidity and made of a fiber impregnated with an adhesive. CONSTITUTION: A polyurethane layer 12 having a fine porosity is provided as a surface layer directed from the surface layer toward a lower layer. Its thickness is 0.2 mm at a maximum, and extremely high porosity of the layer 12 has steam permeability of 1 mg/cm<2> or more per one hour. A foam laminate layer 14 made of a polyurethane dispersant provided adjacent to the layer 12. A measurable thickness of the layer 14 is set to 0.1 mm at a maximum, and the residual thickness is transferred to a fiber layer 16. The layer 16 provided adjacent to the layer 14 is a thickness of 2 mm at the maximum, and the layer 16 is impregnated with normal adhesive to obtain suction and moisture retentivity.</p> |
