ABSTRACT:
A method and apparatus for producing interlaced multifilament yarn having an improved configuration is disclosed. When a material yarn is treated by the 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 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.
