PROBLEM TO BE SOLVED: To provide mixed yarns capable of forming a woven or a knitted fabric having an excellent refreshing feeling at a low cost without polluting the environment even when disposed and a woven or a knitted fabric obtained therefrom. SOLUTION: The mixed yarn is obtained by mixed spinning of low shrinkable fibers A formed from a polylactic acid polymer and highly shrinkable core- sheath conjugated fibers B in which a core part and a sheath part are formed from a polylactic acid polymer, respectively so as to provide a mass ratio A/B of 70/30≤A/B≤90/10. The melting point of the polylactic acid polymer forming the sheath part of the core-sheath conjugated fibers is≥130°C and a lower melting point than that of the polylactic acid polymer forming the core part and the low shrinkable fibers A by≥30°C. The difference between the highly shrinkable core-sheath conjugated fibers and the low shrinkable fibers in shrinkage percentage in boiling water is≥30%. COPYRIGHT: (C)2003,JPO
