    Abstract: The present invention provides a sheet-like material in which a plant-derived raw material of low environmental impact is used. The invention also provides a sheet-like material that ideally has a uniform and refined nap and a sheet-like material that is strong, has excellent shape stability, is lightweight and is very pliable. This sheet-like material is characterized in being made of nonwoven fabric that is made of polyester microfiber containing a 1,2-propanediol-derived component in an amount prescribed in the present application and a polyurethane elastomer resin containing structural monomers prescribed in the present application. This sheet-like material is also made of a base sheet, in which a nonwoven fabric that has microfibers as the main component is laminated and unified with a woven or knitted material, and an elastomer resin, and is characterized in that the woven or knitted material is configured from fibers containing polyester as the main component and that 1-500 ppm of a 1,2-propanediol-derived component are contained in the polyester.

    Abstract: A composite sheet material includes a skin sheet and a woven fabric, wherein the skin sheet is formed by impregnating an elastic polymer into a base material consisting of an entangled fiber network, such as a nonwoven fabric, and wherein the composite sheet material has high thermal resistance and high formability suitable for integral molding. The composite sheet material is a composite sheet material including a skin sheet attached with a woven fabric through an adhesive resin layer, wherein the skin sheet is made of an entangled fiber network including ultra-fine fibers with an average single fiber diameter of 0.1 to 8 μm and of an elastic polymer, and wherein the woven fabric includes polyester fibers in which the polyester contains a 1,2-propanediol-derived component at a concentration of 1 to 500 ppm.
