Title: SUEDE-LIKE SHEET AND METHOD FOR PRODUCING SAME
Abstract:
In the present invention, used is a suede-like sheet that includes a fiber substrate containing a non-woven fabric of ultrafine fiber and a polymer elastic body, and that has a surface having an erect hair region containing erect ultrafine fibers and a plurality of non-erect hair regions which are surrounded by the erect hair region and exist discontinuously and which contain ultrafine fibers that have been thermally fusion-bonded and flattened. The total area of the non-erect hair regions accounts for 5 to 30% of the area of the surface. When X is a mean erect hair length of the erect ultrafine fibers and Y is a total mean length which is the mean of the width of each of the non-erect hair regions, such width being orthogonal to the longitudinal direction, the ratio Y/X is 0.7 to 1.5.
