Embodiment 1～10

[0071] will use figure 1 The fabric woven with the double-layer structure shown is used as the skin material, and the polyurethane foam sheet is laminated on the back of the fabric as the lining material by the flame lamination method according to the conditions shown in the following Table 1, and the composite materials for vehicles of Examples 1 to 10 are obtained. Material. The thickness of the laminated polyurethane foam sheet was 1.3 mm. In the composite materials for vehicles of Examples 1 to 10, the woven fabric as the skin material has a wide gap between adjacent yarns and has a floating gap structure formed by the gap.

[0072] For the fabric used as the skin material in the vehicle composite material of Example 1, 167dtex / 48f×2 2H twisted yarn (300 denier) and 167dtex / 48f twisted yarn (150 denier) are alternately used as warp yarn, and 167dtex / 48f twisted yarn (150 denier) is used as weft yarn. 48f×2 2H twisted yarn (300 denier), set the on-machine density of the w...

[0081] will use figure 2 The fabric woven with the single-layer structure shown was used as the skin material, and a polyurethane foam sheet was laminated on its back side as a lining material by a flame lamination method according to the conditions shown in the following Table 2, and the vehicles of Examples 11 to 25 were obtained. composite material. The thickness of the laminated polyurethane foam sheet was 1.3 mm. In the composite materials for vehicles of Examples 11 to 25, the woven fabrics used as the skin materials all have a wide gap between adjacent yarns and a floating gap structure formed by the gap.

[0082] For the fabric used as the skin material in the vehicle composite material of Example 11, the twisted yarn (150 denier) of 167dtex / 48f is used as the warp yarn, and the twisted yarn (150 denier) of 167dtex / 48f is used as the weft yarn. The density is set to 75 pieces / 25.4mm, use figure 2 Tissue 1 weaving is shown. The number of floating yarns in the warp...

Abstract

Provided is a composite material for vehicles capable of substantially preventing the occurrence of wrinkles caused by ease stitching. This composite material for vehicles is a layered product of a skin material and a polyurethane foam sheet. The skin material has a play structure which, when the composite material for vehicles is stitched, allows the skin material to follow deformation caused bythe stitching with a smooth state of a surface of the skin material maintained. The skin material is a woven fabric including warp yarns and weft yarns. The warp yarns and / or the weft yarns include two or more types of yarns having different total finenesses, and form the play structure.

Description

technical field [0001] The present invention relates to a composite material for vehicles in which a skin material and a polyurethane foam sheet are laminated. Background technique [0002] Surface materials such as vehicle seats are required to be durable, and are not directly used as raw materials, but are used by processing them into composite materials in various forms. Conventionally, when a fabric is used as a skin material in such a composite material for a vehicle, a backing treatment of coating a resin on the back surface of the fabric is performed to prevent abrasion. However, weight reduction of vehicles directly related to reduction of carbon dioxide emitted from vehicles has become an important issue, such as increased awareness of reducing the load on the global environment, and further weight reduction has been demanded for composite materials for vehicles. [0003] For example, there is a composite material for vehicles that omits conventional backing treatm...
