Abstract

La présente invention concerne une fibre cellulosique réticulée dans le papier qu'on obtient en réticulant un mélange de pâte mercerisée et de pâte classique. Ce procédé consiste à chauffer des fibres cellulosiques traitées de façon à favoriser la réticulation à l'intérieur de la fibre. Ces fibres réticulées se caractérisent par une vitesse d'acquisition, une souplesse, un pouvoir absorbant et un pouvoir absorbant sous charge améliorés. Par ailleurs, ces fibres réticulées présentent une réduction dans leur capacité de rétention centrifuge et possèdent des contenus en noeuds, en tortillons et en fractions fines réduits. Les fibres cellulosiques réticulées de cette invention conviennent pour la couche d'acquisition et/ou pour le noyau absorbant d'articles absorbants.
