    摘要： An elastic composite twisted yarn includes a covered elastic yarn (2), having a core yarn (21) formed of an elastic yarn and a sheath yarn 22 formed of a thermoplastic multi filament, and first and second low stretch yarns (3, 4) formed of a thermoplastic multi-filament yarn or a spun yarn. The covered elastic yarn (2) is drawn at a predetermined draw ratio to be inserted into the first low stretch yarn 3 in a combined yarn state. The yarn in the combined yarn state and the second low stretch yarn (4) are combined and twisted to obtain an elastic composite twisted yarn. A plurality of heteromorphic micro-loops formed of a constituent single fiber of the sheath yarn (22), which appears during the relaxation by a contractile force of the covered elastic yarn (2), protruding from the core yarn (21) to a diameter direction, is usually incorporated into a constituent single fiber of the first low stretch yarn (3) and thermally set. It is possible to obtain an elastic composite twisted yarn and floor coverings, which drastically reduce the decline of the crimp, have a feel of expansion for the yarn itself and an appropriate soft texture in addition to the beauty of the appearance, have excellent recoverability to immediately return to the original shape even when the volume is temporarily decreased, and furthermore have excellent elasticity and design characteristics.
