A composite skin material for a vehicle wherein a synthetic leather includes a surface resin layer having a plurality of openings, an adhesion layer present on the rear surface of the surface resin layer, and a fibrous base material present on the rear surface of the surface resin layer across the adhesion layer, and the adhesion layer is present only at the adherend part, except for the plurality of openings, in the rear surface of the surface resin layer, and the base material surface of the fibrous base material is bonded to the surface resin layer.

The present invention provides a sheet structure comprising a carrier layer and a foamed cover layer which contains polyvinyl chloride, lignocellulosic based components and hollow microspheres, and a method for producing the sheet structure. The sheet structure can be used as an artificial leather, e.g. for flexible automotive interiors.

Disclosed is a grain-finished leather-like sheet including: a fiber base material; a polyurethane intermediate layer stacked on the fiber base material; and a polyurethane skin film stacked directly on the polyurethane intermediate layer or via another polyurethane layer, wherein the polyurethane skin film contains a silicone-modified polyurethane, and the grain-finished leather-like sheet has an uneven surface whose skewness (Ssk), kurtosis (Sku), and maximum height (Sz) of surface roughness in accordance with ISO 25178 respectively satisfy −0.4≤Ssk≤−0.2, 3≤Sku≤4, 60 μm≤Sz≤150 μm.

A composite structure is provided that includes a polymer layer and an auxetic material layer disposed within or partially within the polymer layer. The auxetic material layer provides increased conductivity and elastomeric reinforcement to the polymer layer.

This invention relates to fabric for airbag comprising a textile substrate; and a coating layer on at least one side of the textile substrate, wherein coating layer comprises polyurethane resin, a crosslinking agent, and a hydrophilic thickener, and the crosslinking agent is a compound having a blocked active group, and a method for preparing fabric for airbag, comprising steps of: preparing a textile substrate; and forming a coating layer on at least one side of the textile substrate, wherein the step of forming a coating layer comprise steps of: adding a crosslinking agent and a hydrophilic thickener to an aqueous polyurethane dispersion to prepare a coating solution; applying the coating solution one at least one side of the textile substrate; drying the textile substrate on which the coating solution is applied; and heat treating the dried textile substrate.

The present invention provides a sheet structure comprising a carrier layer and a foamed cover layer which contains polyvinyl chloride, lignocellulosic based components and hollow microspheres, and a method for producing the sheet structure.

A method for manufacturing a leather article including a flexible leather includes steps as follows. A leather precursor is provided, wherein the leather precursor includes a polymer material. A release member, the leather precursor and a pressing member are stacked in sequence to form a stacked set, wherein at least one of the release member and the pressing member is formed with a plurality of vents. The stacked set is heated and vacuumized to allow the polymer material to form the flexible leather, such that the leather precursor forms the leather article. The leather article is separated from the release member and the pressing member.

A napped artificial leather includes: a fiber-entangled body obtained by entangling ultrafine fibers: and an elastic polymer impregnated into the fiber-entangled body. The napped artificial leather has, on at least one side thereof, a napped surface formed by napping the ultrafine fibers. The ultrafine fibers contain 0.2 to 8 mass% of carbon black and 0.1 to 5 mass% of a chromatic pigment, and a total ratio of the carbon black and the chromatic pigment is 0.3 to 10 mass%. A content ratio of the elastic polymer is 0.1 to 15 mass% in the napped artificial leather. The elastic polymer is uncolored and the ultrafine fibers are undyed.
