ABSTRACT:
A leather-like sheet excellent in stretchability which is obtained by integrating by entanglement of a woven or knitted fabric and an ultrafine fiber of 0.0001 to 0.5 dtex, wherein at least one face of the leather-like sheet is substantially composed of said ultrafine fibers, and said woven or knitted fabric consists of a conjugate fiber in which two or more kinds of polyester-based polymers, at least one of which consists essentially of polytrimethylene terephthalate, are stuck along the fiber length direction side-by-side, or a conjugate fiber in which two or more kinds of polyester-based polymers, at least one of which consists essentially of polytrimethylene terephthalate, forms an eccentric sheath-core type conjugate structure, and the fiber constituting the woven or knitted fabric has a twist coefficient of 20000 or below.
