The invention provides a method for preparing cross-linked cellulosic fibers. A sheet of cellulosic fibers treated with a caustic solution under non- mercerizing conditions is cross-linked with a solution containing polymeric polycarboxylic acid cross-linking agents. The treated cellulosic fibrous material is dried and cured in sheet form to promote intrafiber cross-linking. Cross-linked fiber products of this method, which is economic, that possess good absorption and wet resiliency properties are also disclosed.

L'invention concerne une méthode de préparation de fibres cellulosiques réticulées. L'invention concerne une feuille de fibres cellulosiques traitée avec une solution caustique, dans des conditions de non mercerisage, réticulée au moyen d'une solution contenant des agents de réticulation d'acide polycarboxylique polymérique. La matière fibreuse cellulosique traitée est séchée et durcie sous forme de feuille pour favoriser une réticulation intrafibre. Les produits fibreux réticulés de cette méthode sont économiques à produire et présentent de bonnes propriétés d'absorption et de résilience à l'humidité.
