ABSTRACT:
Method and apparatus to produce a continuous filament textured yarn with unusually low crimp contraction and intermittent crimp and molecular orientation along its length. This is accomplished by the use of an electromagnetic tension device to control the draw in the yarn being supplied to a false twist device driven at a speed to provide low false twist in the yarn being twisted. The apparatus includes a control between the electromagnetic tension control and the yarn supply package to prevent the yarn coming off the package from rotating in a full balloon path and consequently prevent entanglement of the yarn in the yarn guides as it passes to a yarn consuming machine.
