    摘要: A system for forming a spun bond nonwoven web from extruded polymer filaments includes a spinneret including a plurality of orifices to extrude a plurality of continuous polymeric filaments, and a pressure quench chamber including a top located proximate and below the spinneret and bounded peripherally by surfaces. The quench chamber includes an ingress opening extending substantially across the width of a top of the quench chamber to receive filaments from the spinneret and a chamber exit nozzle extending substantially across the width of a bottom of the quench chamber. The quench chamber has dimensions and a configuration to avoid substantial contact between the filaments and the surface of the quench chamber and a volume sufficient to allow solidification of the filaments within the quench chamber, where the chamber exit nozzle includes a drawing slot at the bottom of the quench chamber extending substantially across the width of the bottom of the quench chamber and in cooperative engagement with the quench chamber to receive the cooled filaments and quench fluid. The drawing slot is formed by lower surfaces of the chamber tapering toward each other in the direction of filament flow through the chamber and terminating at facing edges of two respective knife structures.

    摘要: Production of a yarn, using a spinneret having numerous spinning holes arranged in a straight line(s), and a spinning tube installed below it, spaced from it, and having a filament passage rectangular in cross section with its long side direction agreeing with the direction in which the spinning holes are arranged side by side, wherein gas is injected from the injection holes formed on both the long sides of the filament passage for injecting gas obliquely downward to the filaments, for disposing the numerous filaments in a row and for forming a gas stream flowing downward in the filament passage, characterized in that the speed of the gas stream flowing downward in the filament passage is not less than 60% of the take-up speed of the numerous filaments, or that the gas generated from the numerous filaments is sucked and discharged outside, in the range between the spinneret and the spinning tube. Even if the yarn runs at a high speed, the obtained yarn can have a high elongation.

    摘要: An apparatus for controlling airflow in a fiber extrusion process includes a fiber flow region between an inlet through which extruded fibers are received and an outlet through which the extruded fibers are discharged and at least one surface providing a boundary between the fiber flow region and another region, wherein the surface includes apertures permitting air to flow between the fiber flow region and the other region to control airflow at the outlet of the fiber flow region. The apparatus can include a housing which contains at least one chamber, with the surface forming a boundary between the fiber flow region and the chamber, such that the apertures permit air to flow between the fiber flow region and at the chamber. In a spunbond process, the airflow control device receives drawn filaments exiting an aspirator and deposits the filaments onto a web-forming surface with reduced air disturbance.
