Napped artificial leather and production method thereof

Abstract

Disclosed is a production method of a napped artificial leather including the steps of: providing a fiber sheet including a non-woven fabric of ultrafine fibers with a fineness of 1 dtex or less that has been impregnated with a first elastic polymer; napping one or both surfaces of the fiber sheet to form a napped surface thereon; applying, to the napped surface, a resin solution containing a second elastic polymer having solubility in a predetermined solvent; and applying the predetermined solvent to the surface to which the resin solution is applied. Also disclosed is a napped artificial leather including a fiber sheet obtained by impregnating a first elastic polymer into a non-woven fabric that is an entangled body of ultrafine fibers with a fineness of 1 dtex or less, wherein the fiber sheet includes, on one or both surfaces thereof, a napped surface obtained by the ultrafine fibers, and a second elastic polymer is fixed to basal portions of the napped ultrafine fibers.
