Title
(EN) DURABLE AND DISPERSIBLE CREPED MUTLI-PLY TISSUE
(FR) TISSU MULTICOUCHE RELIÉFÉ DURABLE ET DISPERSIBLE
Abstract
(EN)
Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable and dispersible. The products generally have a Slosh time less than 2 minutes, such as less than about 60 seconds, such as less than about 45 seconds. Surprisingly, the foregoing Slosh times are achieved despite the tissue products having relatively high cross-machine direction (CD) wet tensile strength, such as greater than about 100 g/3". Typically, increasing wet tensile strength, particularly wet CD tensile strength, negatively effects dispersability and increases Slosh time. Despite this trend, the present invention surprisingly provides a tissue product having a relatively high degree of wet strength and good dispersability.
(FR)
L'invention concerne des produits de tissus multicouche comprenant un liant non réticulé qui sont durables et dispersibles. Les produits présentent généralement un temps de ballottement inférieur à 2 minutes, tel que moins d'environ 60 secondes, tel que moins d'environ 45 secondes. De manière surprenante, les temps de ballottement susmentionnés sont obtenus malgré que les produits de tissus présentent une résistance à la traction à l'état humide dans le sens travers (ST) relativement élevée, telle que supérieure à environ 100 g/3 po. Habituellement, l'augmentation de la résistance à la traction à l'état humide, en particulier de la résistance à la traction à l'état humide dans le ST, a une influence négative sur l'aptitude à la dispersion et augmente le temps de ballottement. Malgré cette tendance, la présente invention fournit de manière surprenante un produit de tissu présentant un degré relativement élevé de résistance à l'état humide et une bonne aptitude à la dispersion.
