A method is disclosed for spinning polyester staple to produce dark dyeing yarns as compared to yarns having an otherwise similar composition. The method includes spinning polyester staple into yarn, in which the polyester includes between about 0.5 and 4 percent by weight of polyethylene glycol, into yarn in a rotor spinning machine at a rotor speed of between about 110,000 and 120,000 rpm and at a tension of between about 2.5 and 3.2 grams/tex. A resulting polyester fiber is also disclosed of between about 1.2 and 2.25 denier per filament, and that contains between about 0.5 and 4 percent by weight of polyethylene glycol, and with a fiber tenacity of 4.7 grams per denier or less.
L'invention concerne un procédé de filage de fibres polyester pour produire des fils à coloration sombre comparés à des fils présentant une composition similaire. Le procédé consiste à effectuer le filage de fibres de polyester en fils, le polyester comprenant 0,5 à 4 % environ en poids de polyéthylène glycol, dans un métier à filer à turbine à un régime rotor compris entre 110 000 et 120 000 rpm environ et à une tension comprise entre 2,5 et 3,2 grammes/tex. L'invention concerne également une fibre de polyester obtenue comprenant entre 1,2 et 2,25 deniers environ par filament, contenant entre 0,5 et 4 % environ en poids de polyéthylène glycol et présentant une résistance des fibres inférieure ou égale à 4,7 grammes par denier.
