Claim 6:
7. A method for producing the napped artificial leather according to claim 1, comprising:
preparing a first non-woven fabric comprising an entangled body of ultrafine fiber-generating fibers for forming the ultrafine fibers;
fully impregnating, into voids of the first non-woven fabric, an emulsion for forming the elastic polymer, and subsequently removing a part of the emulsion by squeezing off;
solidifying the elastic polymer in the emulsion applied into the voids of the first non-woven fabric;
forming the ultrafine fibers from the ultrafine fiber-generating fibers to form an artificial leather gray fabric including a second non-woven fabric comprising an entangled body of the ultrafine fibers; and
buffing at least one side of the artificial leather gray fabric;
wherein a squeezing rate at which a part of the emulsion is squeezed off is 30 to 50%.
