Title
(EN) AN APPARATUS FOR PRODUCING A PLURALITY OF DISTINCT YARNS
(FR) APPAREIL DE PRODUCTION D'UNE PLURALITÉ DE FILS DISTINCTS
Abstract
(EN)
An apparatus for producing a plurality of distinct yarns is disclosed. The apparatus includes a hopper configured to remove moisture from polymer and fed to an extruder unit which is configured to melt the polymer and pass through hydro split spinneret to produce the plurality of distinct yarns which further quenched and intermingled to produce torque-free yarns using a texturizing unit. Moreover, the torque-free yarns are wound on a paper tube. The apparatus helps to remove godets to save power.
(FR)
L'invention concerne un appareil de production d'une pluralité de fils distincts. L'appareil comprend une trémie conçue pour éliminer l'humidité du polymère et envoyée à une unité d'extrudeuse qui est conçue pour faire fondre le polymère et passant à travers une filière hydro-fendue pour produire la pluralité de fils distincts qui sont davantage trempés et entremêlés pour produire des fils sans torsion à l'aide d'une unité de texturation. De plus, les fils sans torsion sont enroulés sur un tube en papier. L'appareil aide à retirer les galets pour économiser de l'énergie.
