WOVEN FABRIC

PROBLEM TO BE SOLVED: To provide a polyester woven fabric and a stretching fabric having extremely high bathochromic property, and excellent in stretching property, stretch recovery, soft feeling and warmth-keeping property. SOLUTION: The polyester woven fabric is produced by weaving using a colored wool-blended polyester spun yarn as warp and a colored core-sheath-type conjugated yarn consisting of the core yarn of a false-twisted polyester processed yarn and the sheath yarn of a wool-blended polyester spun yarn as weft, followed by finishing. The stretching fabric is processed so that it has a cover factor K expressed by the equation in the range of 20-50 after processing, and it has a stretch rate of 10-20% in the weft yarn direction and a stretch recovery rate of >=85% in the weft yarn direction. K=T1/√S1+T2/√S2 T1: the number of warps in 1 inch span. T2: the number of wefts in 1 inch span. S1: the yarn number count of the warp (English yarn number count for cotton). S2: the yarn number count of the weft (English yarn number count for cotton).
