Abstract
An apparatus and method for the manufacture of a mixed yarn consisting of two components, continuous filament yarn and staple fibers. The mixed yarn is manufactured by an air jet texturing process. It has been possible to bind the staple fibers undisplaceably into the yarn, and this is ensured by the loops on the continuous filaments produced during texturing. Owing to the formation of a suction zone of the airstream directly before the beginning of actual texturing, the staple fibers can be sucked in and can be blended into the interior of the yarn and can be secured firmly in the yarn by the loops. The invention relates to a new method of manufacture and to an apparatus, or an entire machine, with which the known loop yarn or the new mixed yarn can now be manufactured selectively.
