Abstract:
A method for producing an artificial leather sheet includes (i) coating a solution including an elastic polymer (B) on a substrate layer for forming a composite layer on a surface of the substrate layer, wherein the substrate layer includes ultra fine fibers and an elastic polymer (A), and the substrate layer has ultra fine fiber naps on one surface, the fineness of the ultra fine fibers is 0.0001 to 0.05 dtex, the composite layer includes ultra fine fiber naps and an elastic polymer (B), the ultra fine fiber naps are connected to the fibers constituting the substrate layer, and the elastic polymer (B) is joined to the ultra fine fibers, (ii) pressing the surface of the sheet with an emboss roll for forming hills, and (iii) then coating the top portions of the hills with a solution consisting mainly of an elastic polymer (C).
