Abstract: There is provided a synthetic resin leather having excellent durability against wrinkling and favorable texture without impairing flexibility of a synthetic resin layer when seated. A synthetic resin leather which is used as a skin material for a seat or chair, including: a base cloth layer formed of a knit fabric; and a synthetic resin layer which has flexibility and is joined to one surface of the base cloth layer, wherein the knit fabric is made of filament yarn having a thickness of 111 to 444 dtex and a surface side of the knit fabric is adhered to a back surface side of the synthetic resin layer.

Abstract: Provided is a synthetic resin leather having high flexibility and favorable strength, wear resistance with respect to repeated rubbing, and chemical resistance with respect to contact with a human body. A surface treatment agent including a mixture of a polycarbonate urethane and an ester urethane crosslinked with a carbodiimide is applied to a surface side of a film 1 constituted primarily of vinyl chloride resin, in order to form a surface treatment layer 1a having excellent flexibility, wear resistance and oleic acid resistance.

Abstract: In one form, the present invention provides a synthetic resin leather adhering a base material via an adhesive layer to the back side of a film composed mostly of thermoplastic polyurethane, and the film has on the surface thereof a surface treatment layer formed by coating with a surface treatment agent in which aqueous polycarbonate polyurethane is cross linked by aqueous cross-linking agent containing a carbodiimide group.

Abstract: A synthetic resin leather has a substrate and a synthetic resin layer attached to the substrate. The substrate is a both sides cross-knitted fabric and is prepared by cross-knitting a first yarn with 10 to 40 in count including single spun or mixed spun fibers made of rayon, cotton, polyester, nylon, acryl, or urethane and a second yarn with 50 to 300 in denier including crimpy long fiber filaments, thermoplastic elastomer long fiber filaments or polyurethane long fiber filaments; and knitting the both-sided cross-knitted fabric so loops made of the first yarn and loops made of the second yarn are formed on the front and rear sides of the substrate and are in alternating positions on the front side as compared to the rear side; and, on each side of the substrate, loops of the first and second yarns are formed in alternating positions in longitudinal and transverse directions.

Abstract: In one form, the present invention provides a synthetic resin leather adhering a base material via an adhesive layer to the back side of a film composed mostly of thermoplastic polyurethane, and the film has on the surface thereof a surface treatment layer formed by coating with a surface treatment agent in which aqueous polycarbonate polyurethane is cross linked by aqueous cross-linking agent containing a carbodiimide group.

Abstract: The present invention provides a novel and improved synthetic resin leather comprising a substrate and a synthetic resin layer, wherein it has reduced difference of elongations between in a longitudinal direction and in a transverse direction, desirable thickness, no melting during combustion and excellent feelings and good flame retardant property, which is suitable for use in general applications such as interior finishing materials and/or seats for automobile.

Abstract: The present invention provides a surface material which can be replaced to the conventional surface material made of soft polyvinylchloride resin. This surface material is useful for the various uses such as the material for car interior, surface material furniture or the material for porches. The present invention is the urethane resin surface material comprising, a mixed resin sheet composed of 50-95 wt. % thermoplastic polyurethane and 50-5 wt. % of acrylic soft resin and the Shore A hardness of said urethane resin surface material is 60-80. On one side surface of the mixed resin sheet, a layer of knitted, woven, nonwoven fabric or soft foam sheet can be provided. As the thermoplastic polyurethane resin, the thermoplastic polyurethane resin of Shore A hardness 65-90 is desirable, and as the acrylic soft resin, the acrylic soft resin of Shore A hardness 50-80 is desirable.
