Abstract
(EN)
In a woven fabric fourdrinier forming belt (1) for a cellulose drying machine, the majority of the longitudinal wires in the weave are made from polyamide. To achieve that the finished belt has an elongation of at most 5 % from loose, dry belt to tensioned wet belt, the longitudinal threads are made from a polyamide where the radio between the number of methylene groups and amide groups has a quotient of at least 7. The belt is round woven to a weaving pattern where the longitudinal threads (2) extend in two or more layers. In addition, the belt is stabilized by heating, pressing and stretching such as to obtain a ratio between knuckle height, measured on the inside of the threads, and total belt thickness has a quotient of at most 0.15 for all longitudinal threads (2). The belt has good wear resistance and low extensibility, and is suitable for cellulose driers having limited stretching potential for the belt.
(FR)
Dans une courroie de formage tissée de fourdrinier (1) pour une machine à sécher la cellulose, la majorité des fils longitudinaux du tissu est en polyamide. Pour que l'allongement de la courroie finie lorsqu'elle est mouillée et tendue soit de 5 % au maximum par rapport à la courroie sèche et non tendue, les fils longitudinaux sont en polyamide, le rapport entre le nombre de groupes méthylène et le nombre de groupes amide étant de 7 au moins. Ladite courroie est tissée en rond selon un modèle de tissage dans lequel les fils longitudinaux (2) s'étendent en deux couches ou plus. En outre, la courroie est stabilisée par chauffage, pression et étirage de manière à obtenir un rapport entre la hauteur des bosses mesurée sur l'intérieur des fils, et l'épaisseur totale de la courroie, de 0,15 au plus pour tous les fils longitudinaux (2). Ladite courroie présente une bonne résistance à l'usure et une faible extensibilité, et elle convient aux séchoirs à cellulose ayant un potentiel limité d'étirage de la courroie.
