LEATHER-LIKE SHEET EXCELLENT IN AIR PERMEABILITY AND METHOD FOR PRODUCING THE LEATHER-LIKE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a leather-like sheet excellent in air permeability and a method for producing the same.

SOLUTION: The leather-like sheet includes an entangled nonwoven fabric of ultrafine filament bundles and a first polymer elastic body imparted inside the entangled nonwoven fabric, and the first polymer elastic body is unevenly distributed in a surface layer. The leather-like sheet is provided with casein particles and a surface skin layer including a film that is composed of a second polymer elastic body for covering the casein particles and has a thickness of 50 μm or less on the external surface of the surface layer.
