Abstract

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.
