A high efficiency method of producing a high quality knit fabric is disclosed. The method includes the steps of drafting a blended sliver of cotton fibers and polyester fibers in a four roll drafting zone in which the nip to nip spacing in the break zone is no more than 2.5 mm longer than the effective fiber length of the polyester fibers, and no more than 1.5 mm greater than the effective fiber length in the intermediate zone, and at least 7 mm greater than the effective fiber length in the front zone, thereafter spinning the drafted sliver into yarn at a take up speed of greater than 150 meters per minute, and thereafter knitting the spun yarn into fabric.

L'invention concerne un procédé très efficace pour la fabrication de tissus maille de haute qualité, qui comprend les étapes suivantes: étirage d'un ruban mélangé de fibres de coton et en polyester dans une zone d'étirage à quatre rouleaux, où l'espacement des rouleaux dans la zone de rupture n'excède pas la longueur de fibre effective des fibres en polyester de plus de 2,5 mm, n'excède pas la longueur de fibre effective dans la zone intermédiaire de plus de 1,5 mm, et dépasse la longueur de fibre effective dans la zone frontale d'au moins 7 mm; puis filage du ruban étiré à une vitesse d'admission supérieure à 150 mètres par minute; et enfin tricotage du filé en tissu.
