Abstract
Disclosed is a textured composite yarn composed of a first multifilament yarn having a lower extensibility and a second multifilament yarn having a higher extensibility, as well as a process for manufacturing such textured composite yarn. The first multifilament yarn forms a core yarn, while the second multifilament yarn is wrapped at least partially around the core yarn. Some individual filaments of the second multifilament yarn are entangled and interlaced with some filaments of the first multifilament yarn in the boundary region between the core yarn and the wrapping yarn.
