Title (EN) MELT-SPUN MULTIFILAMENT POLYOLEFIN YARN FORMATION PROCESSES AND YARNS FORMED THEREFROM
(FR) PROCÉDÉS DE FORMATION DE FIL DE POLYOLÉFINE MULTIFILAMENT FILÉ EN FUSION ET FILS FABRIQUÉS AINSI
Abstract:
(EN) A process (10) of making polyolefin multiflament yarn (30) including feeding a polyolefin and a nucleating agent to the inlet (13) of an extruder (12) having a mixing manifold (11), extruding filaments (9) through a spinneret (14) into a cooling bath (16), collecting the filaments with take-up rolls (18, 20) to form a fiber bundle (28), passing the fiber bundle (28) through nip rolls (23, 24, 25, 26) to a finish applicator (22), passing the fiber bundle (28) through an oven (43) and drawing with draw rolls (32, 34) to form a multifilament yarn (30) and winding the multifilament yarn onto a take-up roll (40).
(FR) L’invention concerne un procédé (10) pour réaliser un fil multifilament de polyoléfine (30) consistant à injecter une polyoléfine et un agent de nucléation dans l’entrée (13) d’une extrudeuse (12) ayant un collecteur de mélange (11), à extruder les filaments (9) à travers une filière (14) jusque dans un bain de refroidissement (16), à recueillir les filaments avec des rouleaux de préhension (18, 20) pour constituer un faisceau de fibres (28), à faire passer le faisceau de fibres (28) à travers des rouleaux pinceurs (23, 24, 25, 26) jusqu’à un applicateur de finition (22), à faire passer le faisceau de fibres (28) à travers un four (43) et à l’étirer avec des rouleaux d’étirage (32, 34) pour constituer un fil multifilament (30) et à enrouler le fil multifilament sur un rouleau de préhension (40).
