Abstract: A sheet like article produced from a polyurethane resin has a carbonate group and an oxycarbonyl group as ester groups and has uniform, elegant surface quality, a flexible, highly crease recoverable texture, and high resistance to light and hydrolysis, and also provided is a production method therefore. The sheet like article is produced by adding, as a binder, a polyurethane resin that meets requirements (I) and (II) to a fibrous base material formed mainly of ultrafine fibers: (I) a polyurethane resin such that the polyurethane resin contains, in its interior, an oxycarbonyl group and a carbonate group as ester groups; (II) a polyurethane resin such that the sum of the content of the urethane group and the content of the urea group in the polyurethane resin is 7.0 to 11.0 mass %.

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: Provided is an environmentally friendly process for producing a sheet-shaped material having both an elegant, napped appearance and a soft texture, which qualities have not been achieved concurrently, and also exhibiting good abrasion resistance. The process of the present invention for producing a sheet-shaped material includes the successive steps of (a) adding a polyvinyl alcohol having a degree of saponification of 98% or more and a degree of polymerization of 800 to 3,500 to a fibrous substrate in an amount of 0.1 to 50% by mass relative to the total mass of fibers in the fibrous substrate; (b) adding a waterborne polyurethane to the fibrous substrate with the added polyvinyl alcohol; and (c) removing the polyvinyl alcohol from the fibrous substrate with the added waterborne polyurethane.
