Abstract:
Included are close-couple twisting and heat-setting apparatus, methods of twisting two or more yarns and heat-setting twisted yarn. The apparatus and methods described permit operation at twisting speeds of about 10,000 to 100,000 rpm. In the event that yarn twisting is interrupted, and accumulating system is also included to prevent interruption of heat-setting the twisted yarn. The apparatus and methods are useful in the accelerated production of yarns suitable for soft floor coverings.
