ABSTRACT:
An apparatus for producing interlaced multifilament yarn having an improved configuration is disclosed. When a material yarn is treated by an interlacing apparatus provided with an interlacing nozzle wherein a hollow longitudinal space is formed therein and a jetted fluid is introduced into the hollow longitudinal space, the jet fluid is directed to an axis of the passage of a running yarn in the longitudinal space along a direction substantially perpendicular to the axis of the yarn passage in such a condition that the jet fluid is diffused to a direction along the yarn passage. Accordingly, the individual filaments of the running yarn are vibrated about the axis of the running yarn passage, mainly along a plane defined by the axis of the yarn passage and the axis of a fluid conduit for supplying the jet fluid. According to such effective vibration of the individual filaments, a very stable interlaced configuration of the individual filaments can be created. If the material multifilament yarn is false twisted previous to the interlacing treatment, a more stable interlaced configuration of individual filaments can be created. The thus produced interlaced multifilament yarn has such a superior property that the degree of interlacing is increased by repeated stretch action and, consequently, the multifilament yarn thus produced is very suitable for use as a warp yarn without any additional twisting or sizing operation.
