PURPOSE:To obtain a sheet-like material being flexible, excellent in a sense of fulfillment and feeling of folded crease in forming into a grained sheet-like, further free from protruding feeling on one surface side and having integral feeling and natural leather-like handle. CONSTITUTION:In a sheet-like material consisting of a nonwoven fabric three- dimentionally entangled and a polyurethane binder solidified in microporous state, a polyurethane binder is included into multiple layers of the nonwoven fabric having apparent density gradient in the thickness direction. Thereby, the both of the fiber and the polyurethane binder have apparent density gradient in the same direction of the thickness direction of the sheet-like material. |
