Patent

CA 2524505

The invention relates to a crepe facilitating aqueous composition comprising at least one water-insoluble, non-surface active thermoplastic material having a softening or melting point within the range of from 40~C to 100~C, and at least one water-soluble polymer, preferably a cationic water-soluble polymer. As the composition is comprised in a wet fibre web during creping thereof, a more uniform creping is obtained while the integrity of the web is preserved and dust formation is reduced, and a tissue product having improved properties is provided.

L'invention concerne une composition aqueuse facilitant le crêpage comprenant au moins une matière thermoplastique non active en surface, soluble dans l'eau, présentant un point de ramollissement ou de fusion compris à l'intérieur de la plage allant de 40 ·C à 100 ·C, et au moins un polymère soluble dans l'eau, de préférence un polymère soluble dans l'eau cationique. Comme la composition est renfermée dans un voile de fibres humide, lors du crêpage de celui-ci, un crêpé plus uniforme est obtenu, tandis que l'intégrité du voile est préservée et que la formation de poussière est réduite. On obtient ainsi un produit en tissu présentant des propriétés améliorées.
