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 by the 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.
Claims8
A composite material for vehicles which is a layered product of a skin material and a polyurethane foam sheet, wherein
- the skin material has a play structure which, when the composite material for vehicles is stitched, allows the skin material to follow deformation caused by the 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,
- the difference between the maximum and minimum values of the different total finenesses of the two or more types of yarns included in the warp yarns is 150 denier or more, and
- the difference between the maximum and minimum values of the different total finenesses of the two or more types of yarns included in the weft yarns is 150 denier or more.
