Abstract

Multi-ply fibrous structure products, more specifically embossed multi-ply fibrous structure products and methods for making same are provided.

Claims

exact text as granted — not AI-modified
1. An embossed multi-ply fibrous structure product comprising an x-plane and a y-direction, two or more plies of fibrous structure bonded together along adjacent surfaces of the two or more plies by an adhesive to form a bond area, wherein the bond area is less than about 30% of the bonded adjacent surfaces, wherein the product comprises two faces, wherein one face comprises non-adhesively bonded embossed sites and the other face comprises adhesively bonded non-embossed sites, wherein the embossment sites are non-densified and wherein the non-embossed sites are densified wherein the density of the densified non-embossed sites is greater than the density of the non-densified embossed sites, and the embossed sites extend in the y-direction for the x-plane of the embossed multi-ply fibrous structure product, wherein the fibrous structure product exhibits an embossment height of at least about 1000 μm, and wherein the embossed multi-ply fibrous structure product, when in roll form, exhibits an average effective caliper that is greater than the average sheet caliper of an identical multi-ply fibrous structure in its non-embossed form. 
     
     
       2. The fibrous structure product according to claim  1  10 wherein the two or more plies of fibrous structure are bonded together at a plybond strength of at least about 4 g/in. 
     
     
       3. The fibrous structure product according to claim  1  10 wherein the fibrous structure product exhibits a wet burst of at least about 305 g. 
     
     
       4. The fibrous structure product according to claim  1  10 wherein the fibrous structure product exhibits a sheet caliper of at least about 40 mils. 
     
     
       5. The fibrous structure product according to claim  1  10 wherein the fibrous structure product exhibits a sheet caliper to effective caliper ratio of greater than 1.1. 
     
     
       6. The fibrous structure product according to claim  1  10 wherein the fibrous structure product exhibits a cross machine direction stretch at peak load of greater than 8%. 
     
     
       7. The fibrous structure product according to claim  1  10 wherein the fibrous structure product is in roll form. 
     
     
       8. The fibrous structure product according to claim  1  10 wherein the adhesive is present on the adjacent surfaces in the form of separate, discrete dots and/or separate, discrete stripes. 
     
     
       9. The fibrous structure product according to claim  1  10 wherein at least one of the two or more plies of fibrous structure comprises a fibrous structure selected from the group consisting of: through-air-dried fibrous structure plies, differential density fibrous structure plies, wet laid fibrous structure plies, air laid fibrous structure plies, conventional fibrous structure plies and mixtures thereof. 
     
     
       10. An embossed multi-ply fibrous structure product comprising two or more plies of fibrous structure bonded together along adjacent surfaces of the two or more plies by an adhesive to form a bond area, wherein the bond area is less than about 30% of the bonded adjacent surfaces, wherein the product comprises two faces, wherein one face comprises non-adhesively bonded non-densified embossed sites, wherein the embossment sites result from the protuberances of one embossing roll engaging with the depressions of another embossing roll and extend in the y-direction from the x-plane of the structure, and the other face comprises adhesively bonded densified non-embossed sites, and wherein the fibrous structure product exhibits an embossment height of at least about 1000 μm, and wherein the densified non-embossed sites have a density that is greater than the density of the non-densified embossed sites.
