ABSTRACT:
Method for producing an interlaced multifilament yarn comprising previously rubbing and scratching a material multifilament yarn with an intensity such that the individual filaments constituting the multifilament yarn are not substantially broken by a rotary rough surface member having sharp projections which are smaller than the cross-sectional diameter of the individual filament of the multifilament yarn; then diffusing at least one jetted fluid, each jetted in the yarn running direction along a predetermined yarn passage from a jetting aperture of a supply conduit through a nozzle formed with a rectifying and diffusing portion having a substantially uniform section with the supply conduit being fixed with respect to the members defining the yarn passage; and then impinging the diffused jetted fluid against the running material multifilament yarn so that the individual filaments of the multifilament yarn mostly vibrate in a direction which is substantially parallel to a plane defined by the yarn running direction and the fluid jetting direction with the vibration taking place in a section of the yarn passage facing the rectifying and diffusing portion.
