PURPOSE:To obtain a fabric having excellent handle, etc., by subjecting conjugate yarn comprising a specific copolyester and another fiber-forming polymer to alkali weight-loss treatment and partially dissolving the copolyester. CONSTITUTION:Fabric, yarn, etc., comprising conjugate yarn obtained by subjecting (A) a copolyester composed of A1: 0.5-10mol% of a dicarboxylic acid unit of formula I (Ar is trifunctional aromatic group; M is metal atom) based on total acid components constituting the copolyester, A2: 1-49wt.% of a diol unit of formula II (R<1> is alkylene; (m) is 10-100) and 1-49wt.% of a side chain group unit of formula III (R<2> is alkylene; R<3> is 1-18C hydrocarbon; (n) is 10-100; (x) and (y) are 0 or 1) based on the weight of the polyester, and 2-50wt.% total of the components A2+A3 and (B) another fiber-forming polymer having alkali solubility lower than that of the component A is treated with an alkali and the component A is partially dissolved in a short time to give fabric composed of surface yarn similar to soft natural yarn. |
