Multiply tissue product
A multiply tissue product comprising at least two plies of a tissue interconnected to each other. The multiply tissue further comprises a layer including super absorbent fiber-like particles in at least one interface region in between two adjacent plies of the tissue webs, wherein the basis weight of the layer is between about 0.5% and about 50% of the overall basis weight of the two adjacent plies of tissue.
1. A multi-ply-tissue product comprising:
at least two plies of tissue interconnected to each other at an interface region, the at least two plies of tissue being interconnected by a plurality of embossments, the embossments forming at least one compartment disposed within the interface region; and
a layer comprising super absorbent fiber-like particles disposed within the interface region, at least a portion of the super absorbent fiber-like particles being disposed within the at least one compartment; and,
wherein the basis weight of the layer comprising super absorbent fiber-like particles is between about 0.5% and about 50% of the overall basis weight of the two adjacent plies of the tissue defining the interface region;
wherein the multiply tissue is selected from the group consisting of paper towels, napkins, and hankerchiefs; and wherein the super absorbent fiber-like particles are present in the layer at a basis weight of about 0.2 to about 5.0 g/m 2 .
2. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles are present in the layer at a basis weight of about 0.5 to about 2.0 g/m 2 .
3. The multi-ply tissue product of claim 1 wherein the basis weight of the layer comprising super absorbent fiber-like particles is between about 1% and about 3% of the overall basis weight of the two adjacent plies of the tissue defining the interface region.
4. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles have a length from about 3 to about 30 mm.
5. The multi-ply tissue product of claim 4 wherein the super absorbent fiber-like particles have a length of about 4 to about 10 mm.
6. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles have a fiber diameter from about 5 to about 50 μm.
7. The multi-ply tissue product of claim 6 wherein the fiber diameter is from about 20 to about 30 μm.
8. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles have a density from about 1.0 to about 2.0 g/cm 3 .

10. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles are fixed by a glue coating providing for the interconnection of the two plies of tissue.
11. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles are fixed by a glue coating sprayed onto at least one of the plies of the tissue.
12. The multi-ply tissue product of claim 1 wherein the super absorbent fiber-like particles are fixed by glue filaments, forming a network with the super absorbent fiber-like particles on at least one of the plies of tissue webs.
13. The multi-ply tissue product of claim 1 wherein the layer comprising super absorbent fiber-like particles consists essentially of super absorbent fiber-like particles.
14. The multi-ply tissue of claim 13 wherein the basis weight of the layer comprising super absorbent fiber-like particles is between about 0.5% and about 10% of the overall basis weight of the two adjacent plies of the tissue defining the interface region.
15. The multi-ply tissue product of claim 1 wherein the layer comprising super absorbent fiber-like particles includes cellulosic paper fibers and forms an individual layer in which the super absorbent fiber-like particles are embedded into the layer together with the cellulosic paper fibers.
16. The multi-ply tissue product according to claim 15 wherein the basis weight of the layer comprising super absorbent fiber-like particles is in the order of about 10% to about 35% of the overall basis weight of the two adjacent plies of said tissue defining the interface region.
