PROBLEM TO BE SOLVED: To obtain a blended yarn having excellent water absorbability and useful for woven or knitted fabrics having excellent soft touches, draping property, tension and stiffness. SOLUTION: This blended yarn having water absorbability comprises (A) polyester multifilaments which extend on a dry thermal treatment at 160 deg.C and (B) polyester multifilaments which shrink on the dry thermal treatment at 160 deg.C. The polyester multifilaments A in the blended yarn have fine grooves in the direction rectangular to the filament axes. The blended yarn, and a woven fabric using the blended yarns as warps and/or wefts satisfy the following relationships. (The blended yarn); the single filament fineness of the polyester multifilaments A: 0.2 to 1.0 denier, SHD (A)<0%, 40%>=SHD(B)>=5%, and 45%>SHD(B)-SHD(A)>=5%. (The woven fabric); the number of the single filaments of the polyester multifilaments A occupying the warp: 5,000-30,000 filaments/cm. Therein, SHD(A), SHD(B) are the shrinkage degrees of the polyester multifilaments (A) and (B), respectively, on the dry thermal treatment at 160 deg.C.
