Abstract (en)
[origin: US2013287990A1] An elastic composite twisted yarn includes a covered elastic yarn, having a core yarn formed of an elastic yarn and a sheath yarn formed of a thermoplastic multi filament, and first and second low stretch yarns formed of a thermoplastic multi-filament yarn or a spun yarn. The covered elastic yarn is drawn at a predetermined draw ratio to be inserted into the first low stretch yarn in a combined yarn state. The yarn in the combined yarn state and the second low stretch yarn 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, which appears during the relaxation by a contractile force of the covered elastic yarn, protruding from the core yarn to a diameter direction, is usually incorporated into a constituent single fiber of the first low stretch yarn and thermally set.
