Title
(EN) HIGH BULK TISSUE COMPRISING CROSS-LINKED FIBERS
(FR) TISSU TRÈS GONFLANT COMPRENANT DES FIBRES RÉTICULÉES
Abstract
(EN)
The present application relates to a cross-linked fiber and more specifically to fibers that have been subjected to cold caustic extraction (at less than 60°C) to reduce the hemicellulose content of the fibers by at least 50% and then cross- linked with a cross-linking agent that is curable at a modest temperature, such as less than 160°C. The treated cross- linked fibers preferably have a hemicellulose content that is less than 5% by weight of the fiber. Preferable cross-linking agents are polyamide-epichlorohydrin (PAE) resins, polyamide-polyamine-epichlorohydrin (PPE) resins, and polydiallylamine-epichlorohydrin resins. The cross-linked fibers are readily dispersible in water even without fiberization and generally form webs and products having relatively few knits or knots. As such, the cross-linked fibers of the present invention are well suited for use in the manufacture of tissue webs and products, particularly wet-laid tissue webs and products.
(FR)
La présente invention concerne une fibre réticulée et, plus précisément, des fibres qui ont été soumises à une extraction alcaline à froid (à moins de 60 °C) pour réduire d'au moins 50 % la teneur en hémicellulose des fibres, puis qui ont été réticulées à l'aide d'un agent de réticulation durcissable à une température modeste, inférieure à 160 °C. Les fibres réticulées traitées ont de préférence une teneur en hémicellulose qui est inférieure à 5 % en poids de la fibre. Les agents de réticulation sont de préférence des résines de polyamide-épichlorhydrine (PAE), des résines de polyamide-polyamine-épichlorhydrine (PPE) et des résines de polydiallylamine-épichlorhydrine. Les fibres réticulées peuvent facilement être dispersées dans l'eau même sans défibrage et forment généralement des bandes et des produits ayant relativement peu de mailles ou de nœuds. De ce fait, les fibres réticulées de la présente invention sont appropriées pour être utilisées dans la fabrication de bandes de tissu et de produits, en particulier de bandes de tissu et de produits obtenus par voie humide.
