A method of producing an entangled fabric for artificial leathers including a step of uniting a woven/knitted fabric and an entangled nonwoven fabric by entanglement. The method includes (1) a step of superposing the woven/knitted fabric on one surface of the entangled nonwoven fabric; (2) a step of needle-punching the superposed body from a side of the entangled nonwoven fabric so as to allow fibers constituting the entangled nonwoven fabric to enter into the woven/knitted fabric and then penetrate through the woven/knitted fabric, thereby forming a nonwoven fabric layer composed of the penetrated fibers on an outer surface of the woven/knitted fabric; and (3) a step of needle-punching from a side of the nonwoven fabric layer so as to allow a part of the fibers which have penetrated through the woven/knitted fabric and form the nonwoven fabric layer to turn back into the woven/knitted fabric, thereby uniting the woven/knitted fabric and the entangled nonwoven fabric together by entanglement. The method hardly causes wrinkles, etc. and is good in process passing properties. The artificial leathers produced from the entangled fabric for artificial leathers have a good shape stability, a high-quality appearance and a soft, high quality hand.
