Leather-like sheet and production method thereof

A method of producing a leather-like sheet that substantially does not contain polyurethane comprising 1) obtaining an ultra-fine staple fiber nonwoven fabric (A′) in which staple fibers convertible into ultra-fine fibers of an average single fiber fineness of about 1 to about 10 dtex which are convertible into ultra-fine fibers of an average single fiber fineness of about 0.0001 to about 0.5 dtex and an average fiber length of about 1 to about 10 cm are entangled by needle punching and then converted into ultra-fine fibers, and 2) laminating said nonwoven fabric (A′) on a woven or knitted fabric (B) comprising a conjugate fiber in which two or more polyesters are disposed in side-by-side or eccentric sheath-core relationship and subjecting (A′) and (B) to a fluid jet treatment at a pressure of at least about 10 MPa to entangle the ultra-fine fibers in the nonwoven fabric (A′) with each other to convert it into a nonwoven fabric (A) simultaneously with entangling the nonwoven fabric (A) and the woven or knitted fabric (B).
