Patent

CA 2460152

An absorbent cellulose material having an application of superabsorbent polymer adhered to the cellulose material. In particular, the cellulose material has an application of pre-superabsorbent polymer adhered to the material, wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to superabsorbent polymer upon subjected to heat for a sufficient time. The absorbent cellulose material has a fluid retention of greater then 2g/g.

L'invention se rapporte à une matière cellulosique absorbante sur laquelle a été appliqué un polymère superabsorbant, qui adhère à la matière cellulosique. En particulier, un polymère pré-superabsorbant a été appliqué sur la matière cellulosique et adhère à cette dernière, une solution aqueuse contenant le polymère pré-superabsorbant étant appliquée sur la matière cellulosique, le polymère pré-superabsorbant étant transformé en polymère superabsorbant lorsqu'il est soumis à la chaleur pendant une période de temps suffisante. La matière cellulosique absorbante présente une rétention de fluides supérieure à 2g/g.
