Leather-like sheets and method for producing them

摘要

Provided is a leather-like sheet that comprises microfine fibers of an inelastic polymer having a mean fiber diameter of at most 5 ?m and an elastic polymer, in which the major portion of the elastic polymer forms a fibrous structure of the entangled nonwoven fabric with the microfine fibers of inelastic polymer throughout the entire layer of the leather-like sheet in the thickness direction thereof, and a part of the elastic polymer forms a porous layer integrated with the entangled nonwoven fabric structure on at least one face of the leather-like sheet. The leather-like sheet does not substantially undergo structure deformation even when repeatedly elongated and deformed. It has good elastic stretchability, and has a soft and dense feel, and its appearance is good not detracting from the drapability of the sheet.
