して乾くまでに長時間かかるという問題もあった。(Prior art) Furniture and vehicle interior materials that are integrally vacuum-molded using foamed synthetic resin such as polyurethane foam include foamed synthetic resin such as polyurethane foamed sheet on the back side of woven fabric to decorate the outer surface. A laminated skin material in which resin layers are laminated is used, but in order to perform vacuum forming efficiently, a material in which a non-ventilated synthetic resin film is laminated on the back side of the foamed synthetic resin layer is generally used. However, when such a laminated skin material is used, the woven fabric tends to bend in areas with large bending angles called deep drawing areas, such as corner areas where the seat and backrest of a chair are connected. There is a problem in that bubbles occur and the product value is significantly reduced, and there is also a problem in that when water or the like spills, it penetrates into the inner polyurethane foam resin layer and takes a long time to dry.

Furthermore, it was completed with the aim of providing a laminated skin material that does not wet the inner foamed resin layer even if water or the like adheres to it, dries immediately, and provides excellent handling properties.

とは確実に防止されることとなる。(Function) Such a laminated skin material for vacuum forming is formed by applying suction into a vacuum forming mold to form a skin having a deep drawing part, and then injecting and foaming the raw material for the cushion body made of polyurethane foam on the back side. By integrating the skin into a cushion body made of polyurethane foam, it is similar to conventional laminated skin materials of this type, but the foamed synthetic resin layer on the back side is removed at the deep drawing part during vacuum forming. The unevenness that occurs on the woven fabric is alleviated by the synthetic resin film interposed between the woven fabric and the unevenness no longer appears on the woven fabric surface, making it possible to provide a product with a good appearance. The synthetic resin film also blocks penetration into the interior, thereby reliably preventing the thick foamed synthetic resin layer from getting wet.

A synthetic resin film (2) made of synthetic resin is laminated. This synthetic resin film (2) is indispensable for vacuum suction into the mold during vacuum integral molding, which will be described later, and for example, one having a thickness of 30 to 50 μm is used. The back side of this synthetic resin film (2) is coated with 3-1511II for providing cushioning properties.

被覆させる必要もなくなるという効果もある。The laminated skin material constructed in this way is used, for example, as a decorative skin material for a seat chair 00) that is vacuum-integrated as shown in Fig. 2, and the woven fabric (1) is placed in a mold. After being vacuum-adsorbed in the mold to bring them into contact,
The seat 00) is formed by integrally molding the laminated skin material on the surface of the cushion body (4) made of urethane foam by injecting and foaming the foamable polyurethane raw material.In this case, the laminated skin material Since the non-breathable synthetic resin film (2) is laminated on the surface, it is reliably suctioned closely along the shape of the mold, similar to conventional laminated skin materials.Moreover, the synthetic resin film (2) Woven cloth (
1) and the foamed synthetic resin layer (3), the synthetic resin film has irregularities generated in the foamed synthetic resin layer (3) even in the deep drawing section and is interposed between the woven fabric (1) and the foamed synthetic resin layer (3). (2
), and no unevenness will appear on the surface of the woven fabric (1). Therefore, the woven fabric (1) does not have wrinkles in the deep-drawn portion as in conventional fabrics, and a chair 0ω with an excellent appearance and high commercial value can be obtained. Also,
During foam molding, the foamable urethane raw material penetrates into the pores of the foamed synthetic resin 11 (3) and solidifies, forming an impregnated layer (5) with a low foam density and higher rigidity than the cushion body. Layer (5) eliminates the feeling of bottoming out when sitting, resulting in a seat with excellent tactility. Furthermore, even if water or the like is spilled on the surface of the seat 00), there is a synthetic resin film (2) under the woven fabric (1), so even the thick foamed synthetic resin layer (3) will not get wet. It is extremely easy to handle because it can be dried immediately by wiping it off. Furthermore, when the laminated skin material according to the present invention is sewn into a plurality of divided pieces to form a bag-like cover, the adhesiveness of the synthetic resin film (2) in the part where the suture system penetrates is high, resulting in airtightness. This also has the effect that there is no need to cover the sutured portion with a separate member for airtightness as in the past.

In addition, even if water etc. adheres, the inner foamed synthetic resin layer does not get wet and dries immediately, giving it excellent handling properties. It will greatly contribute to the development of industry by eliminating the problems with wood.
