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.
