Abstract

PURPOSE:To obtain leather-like sheets of excellent flexibility and drapeability, by forming a porous skinless surface layer of a specific polyurethane on the fibrous sheet base, and coating the porous structure with another specific polyurethane to form the surface layer having fine particles on its surface. CONSTITUTION:A fibrous base 1 made of a synthetic fiber such as polyamide or polyester, preferably ultrafine synthetic fibers is coated with polyurethane I prepared from an organic diisocyanate containing aromatic rings, coagulated to form the surface layer of a porous structure. Then, the skin layer is removed by buffing to give the skinless surface layer 2, and the buffed surface is coated with polyurethane II prepared from an aliphatic isocyanate and/or alicyclic isocyanate to form a polyurethane coating layer 6 having fine particles on its surface whereby a leather-like sheet whose porous surface layer 2 has 15-300mum average pore size and 0.25-0.48g/cm<3> apparent density is obtained. This sheet is excellent in air and moisture permeability, and abrasion resistance.
