A STUDY OF THE MOTION OF LOW STRETCH YARN WITHIN AN INTERLAGER

This article discloses the movement of a false-twist yarn in the passageway of an interlacer under the air fluid action and the fluid rule of the air in the passageway of the interlacer during the interlacing process by means of experiment. The experiments are based on the high-speed photography and showing the moving track of the air methods. According to the results of the experiments, we find that the false-twist yarn are splaying and vibrating, the single filament or a bundle of filaments which departed from the yarn will rotate. In order to supply the foundation to designing the configulation of the interlacer, we further explain the periodic interlacing formation mechanism in the interlacing process.
