(FR) FIBRE AYANT DES CARACTÉRISTIQUES DE TRAITEMENT AMÉLIORÉES ET SON UTILISATION
Abstract
(EN)
The present invention relates to manmade cellulosic fibers having optimized processing characteristics in yarn spinning while improving yarn quality. Particularly, the invention relates to a manmade cellulosic fiber having improved running characteristics in the production of yarn, which in the finished state has a QPG value of 1.0 or more, preferably 1.0 to 3.0, more preferably 1.0 to 1.8, QPG being calculated as follows: QPG = (WHV x moisture x sinking time) / (DGW x FK x pH x crystallinity). Furthermore, the present invention relates to the use of this fiber for the production of a yarn by means of ring spinning, compact spinning, rotor spinning, or air-jet spinning.
(FR)
La présente invention concerne des fibres cellulosiques synthétiques ayant des caractéristiques de traitement optimisées dans la filature de fil tout en améliorant la qualité du fil. En particulier, l'invention concerne une fibre cellulosique synthétique ayant des caractéristiques de fonctionnement améliorées dans la production de fil, qui, à l'état fini, a une valeur de QPG de 1,0 ou plus, de préférence de 1,0 à 3,0, de préférence encore de 1,0 à 1,8, le QPG étant calculé comme suit : QPG = (WHV x humidité x temps de sédimentation) / (DGW x FK x pH x cristallinité). En outre, la présente invention concerne l'utilisation de cette fibre pour la production d'un fil au moyen d'une filature à anneaux, d'une filature compacte, d'une filature à rotor ou d'une filature à jet d'air.
