ABSTRACT:
A textured composite yarn having the appearance and touch of a cotton yarn comprises a core yarn and a sheath yarn composed of a plurality of filaments, said sheath yarn wrapping around the core yarn. A part of the filaments of the sheath yarn wrap around the core yarn with a successive alternate twist and are substantially cohered and partially adhered to the core yarn. The composite yarn is made by simultaneous draw-false twisting and heating two component yarns having different fusing temperatures, one of the component yarns being overfed in relation to the other component yarn.
