Abstract
A suede woven fabric comprises a warp yarn selected from the group consisting of polyester textured yarn, polyester filament yarn and polyester spun yarn, and a weft yarn of polyester island filaments whose mean thicknesses in denier are within the range from 0.05 to 0.50 and whose degree of variation of thickness is 15 to 60%; wherein a portion of said island filaments on at least one surface of the fabric is raised to form piles of individual island monofilaments whose mean lengths are from 0.5 to 4.0mm; wherein the number of floating points on said weft yarn, whose number of floats in within the range of 3 to 11, is 100 to 500/cm.sup.2 of woven fabric, and wherein the relation between the shear stiffness G.sub.0.5 at a shear angle of 0.5.degree. and the stiffness G.sub.5 at a shear angle of 5.degree., represented by G.sub.5 /G.sub.0.5, is 1.5 to 15.
