A method for target application of a Performance Enhancing Material(77, 78, 79) to a creping cylinder (30) in order to improve a tissue making operation is described and claimed. The method involves dividing the creping cylinder (30) into Zones (15, 17, 18, 19, 28, 38) and then applying the desired Performance Enhancing Material (77, 78, 79)on a Zone by Zone basis such that each Zone has the optimal Performance Enhancing Material (77, 78, 79) present. Furthermore, a method to ascertain the amount and pattern of application of the Performance Enhancing Material (77, 78, 79) used on the creping cylinder (30) is described and claimed. This method involves adding an inert fluorescent tracer to said Performance Enhancing Material and then to use a fluorometer to look for the tracer on the creping cylinder (30), and/or on the creped tissue product and/or the water removed from the felt.
L'invention concerne un procédé d'application ciblée d'un matériau améliorant la performance sur un cylindre de crêpeuse afin d'améliorer une opération de fabrication de tissu. Le procédé consiste à diviser le cylindre de crêpeuse en zones, puis à appliquer le matériau améliorant la performance désiré zone par zone, de manière que chaque zone comprenne un matériau améliorant la performance optimal. L'invention concerne également un procédé permettant d'établir avec précision la quantité et le modèle d'application du matériau améliorant la performance utilisé sur le cylindre de crêpeuse. Le procédé consiste à ajouter un dispositif de traçage fluorescent inerte audit matériau améliorant la performance, puis à utiliser un fluoromètre pour retrouver le dispositif de traçage sur le cylindre de crêpeuse, et/ou sur le produit de tissu crêpé et/ou dans l'eau retirée du feutre.
