LEATHERY SHEET HAVING NAP OF ULTRAFINE FIBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a napped sheet of ultrafine fibers having color fastness to light and color fastness to rubbing at high levels and a good napped state in combination and to provide a method for producing the same. SOLUTION: The napped sheet of the ultrafine fibers comprises an entangled nonwoven fabric composed of the ultrafine fibers of≤0.5 dtex and a polymer elastomic body filling the interior thereof and has at least one raised surface. In the napped sheet of the ultrafine fibers, the napped sheet is colored with an aqueous pigment having dyeability and a formulation composed of a low-molecular weight polyurethane and a silicone resin is applied to the surface of the napped sheet.
