A nubuck-like woven fabric comprising a two-layered structural yarn wherein ultra-fine polyester multifilaments are primarily disposed in a sheath portion and polyester multifilaments having a larger single fiber thickness are primarily disposed in a core portion, and having an apparent specific gravity of 0.35-0.7 and a shear rigidity of 0.5-1.2 gf/cm.multidot.deg. This woven fabric is produced by a method wherein a woven fabric of a two-layered structural yarn composed of (i) side-by-side type or islands-in-sea type composite multifilaments comprising (a) a readily soluble ingredient and (b) ultra-fine multifilaments-forming ingredient and (ii) highly shrinkable multifilaments, is subjected to a treatment for dissolving and removing ingredient (a) without substantial shrinkage of the two-layered structural yarn, then, the woven fabric is shrunk in a widespread state.
A nubuck-like woven fabric comprising a two-layered structural yarn wherein ultra-fine polyester multifilaments having a single fiber thickness of 0.001 to 0.5 denier are primarily disposed in a sheath portion and polyester multifilaments having a single fiber thickness larger than that of the ultra-fine polyester multifilaments are primarily disposed in a core portion;
method of producing a nubuck-like woven fabric characterized in that:
