Beschreibung
Zusammenfassung:	An absorbent composite material may be manufactured by applying a flexible absorbent binder polymer (FAB), also referred to herein as a flexible superabsorbent, during the creping step of conventional tissue manufacturing. As such, the costly process of applying FAB to a substrate by spraying or printing followed by drying may be eliminated. The creping step has the additional advantage of improving the flexibility and softness of the FAB treated fibrous web. La présente invention concerne un matériau composite absorbant qui peut être fabriqué par application d'un polymère liant absorbant flexible (FAB), également appelé présentement superabsorbant flexible, pendant l'étape de crêpage de fabrication de tissu conventionnel. En tant que tel, le procédé coûteux d'application de FAB sur un substrat par pulvérisation ou impression suivie par séchage peut être éliminé. L'étape de crêpage présente l'avantage additionnel d'amélioration de la flexibilité et de la souplesse de la bande fibreuse traitée avec FAB.
