A composite skin material for a vehicle includes a fibrous substrate, a polyurethane resin layer provided on the front side of the fibrous substrate, and a woven fabric adhered to the back side of the fibrous substrate through an adhesive layer comprising a polyurethane resin. Openings penetrating the fibrous substrate from the front of the polyurethane resin layer are provided in the composite skin material, and an opening ratio on the front of the polyurethane resin layer is 1 to 15%. The woven fabric has a warp density of 25 to 50 yarns/25.4 mm and a weft density of 30 to 50 yarns/25.4 mm, and the mass per unit area of the adhesive layer is 15 to 100 g/m. The composite skin material has air permeability of 5 to 100 cm/cm&#xb7;s, tear strength of 20 to 150N, and tensile strength of 50 N/cm or more.

Composite skin material for vehicle

Stretchable artificial leather comprising a fibrous substrate comprising tricot knitted fabric, and a polyurethane resin layer laminated on the surface of the fibrous substrate, the stretchable artificial leather having fixed load elongation of from 30 to 60% in each of a longitudinal direction, a lateral direction and a bias direction.

Stretchable artificial leather

A three-dimensional knitted fabric having front and back ground structures and an interconnection yarn uniting the ground structures. At least one of the front and back ground structures of the three-dimensional knitted fabric has an uneven pattern with projections and depressions having a great level difference. Ground yarns of the at least one ground structure are traversed by a predetermined traverse width so that the projections each have a curved shape having a distinct curvature in section, and cast off at predetermined intervals so that the depressions each have an opening.

Three dimensional knitted fabric having unevenness

A three-dimensionally constructed warp knit fabric formed to include front-surface and back-surface ground knit constructions and connection yarns interconnecting the front-surface and back-surface ground knit constructions has insertion yarns between the connection yarns, in which the insertion yarn is fixed along the inner side of the back-surface ground knit construction. Further, the insertion yarn is fixed by a fixing yarn to the back-surface ground knit construction.

Three-dimensionally constructed warp knit fabric with slippage-preventive yarns

It is to provide a three-dimensional warp-knitted fabric in which breathability and cushioning property especially are well suited for a motor vehicle seat in a manner that a feeling of stickiness and steaminess when sweating is eliminated. The three-dimensional warp-knitted fabric comprising front and back ground structures, one of which has a smaller number of loops (), the other ground structure having a larger number of loops (); and connecting yarns for connecting these two ground structures (). One of the ground structures () and the other ground structure () being knitted with different number of needles, and the number of loops of the ground structure having the smaller number of loops () being 30 to 75% that of the other ground structure having the larger number of loops (). Moreover, the per-area weight of the ground structure having the small number of loops is 60 to 150% of the ground structure having the larger number of loops.

Warp knit fabric with steric structure

A three-dimensionally structured warp knitted fabric has a higher compressibility and resiliency than its conventionally available counterpart, as well as enhanced abrasion resistance to prevent fuzzing. The three-dimensionally structured warp knitted fabric includes a top substructure and a bottom substructure, either of which is a net texture, the other being a plain texture. Substructure connecting yarns connect the two substructures. A plurality of connecting yarn controlling yarns are present between the two substructures and between the substructure connecting yarns. The connecting yarn controlling yarns control the substructure connecting yarns by handling, separating and holding them. The connecting yarn controlling yarns include portions which are stitched into the plain texture side of the top or bottom substructure and portions which are floating between the top and bottom substructures.
