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.

Abstract: A sheet material includes a fibrous substrate made of microfibers and a hydrophilic-group-containing resin applied to the fibrous substrate. The hydrophilic-group-containing resin has a microphase-separated structure that satisfies Condition I: In a phase image obtained by observing an area of 1 μm2 in a cross-section of the hydrophilic-group-containing resin applied to the fibrous substrate by phase imaging using an atomic force microscope (AFM), a standard deviation of a mode of brightness distribution of areas of 0.2 μm2 in the area of 1 μm2 is from 0 to 10. Provided are a sheet material that is produced through an eco-conscious production process and yet has such uniformity that is comparable to those of man-made leathers produced using organic-solvent-based polyurethanes, an elegant surface appearance, and a good touch, and a method for producing such a sheet material.
