    Abstract: Method for producing an interlaced multifilament yarn by rubbing and scratching a material multifilament yarn with a rotary rough surface member and with such intensity that individual filaments constituting the filament yarn are not substantially broken, the rotary surface member having projections which are smaller than the cross-sectional diameter of the individual filaments of the material yarn; diffusing a jetted fluid which is 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 cross-section, and 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 substantially parallel to a plane defined by the yarn running direction and the fluid jetting direction, the vibration taking place in a section of the yarn passage facing the rectifying and diffusing portion.

    Abstract: PURPOSE:To obtain the titled fibers having high antistatic properties and physical properties of the fibers with good stability, by extruding a polyamide containing a copolymerized polyalkylene ether compound, etc., as a core component in a specific melt residence time, and carrying out conjugate spinning at a high speed using a polyamide as a sheath component. CONSTITUTION:20-40wt% polyamide composition containing a copolymerized polyalkylene ether compound and a polyamide as a core component are introduced from a spinneret inlet part 1 of the core component through a metering hole 2, and a polyamide which is a sheath component is introduced from a spinneret inlet part 3 of the sheath component into the spinneret. Both are then joined in a joining part 4 and formed into a conjugate polymer stream, which is then extruded through a spinneret extrusion hole 6 at 1,500-9,000m/min spinning speed to give within 5-60min melt residence time of the sheath component. Thus, the aimed fibers are obtained.
