Abstract
This invention relates to a process for the continuous manufacture of smooth or textured multifilament yarns from synthetic thermoplastic high molecular weight polymers by the spin stretching or spin stretch texturing processes, wherein the unstretched multifilament yarn is passed from the spinning machine to the stretching or stretch texturing machine through tubes made of metal, plastics or glass, although other materials may also be used, e.g. ceramics.
