Summary: | A method is provided for applying a superabsorbent polymer to a fibrous sheet material. The fibrous sheet material may be a nonwoven material or a tissue paper. The method includes applying a crosslinkable polymeric dispersion or solution onto the fibrous sheet material by printing technique and in a separate step applying a crosslinking agent onto the fibrous sheet material by printing technique, wherein said crosslinking agent accomplishes crosslinking of the crosslinkable polymer to form a superabsorbent material. A tissue or nonwoven product-includes at least two plies that are bonded together, wherein a crosslinked superabsorbent material is applied in a printed pattern between the plies, said tissue or nonwoven product having a DIN54540 Water Absorption between 15 and 100 g/g. |
