Abstract

An embossed multi-ply fibrous structure product having enhanced quilted appearance comprising: two or more plies of fibrous structure wherein at least one of the piles has a plurality of embossments thereon having a total embossment area of from about 6% to about 16%; the embossments forming a latticework defining a plurality of unembossed cells; wherein each cell has a surface area of from about 0.5 square inches to about 6 square inches, the cells being unadhered to the adjacent ply and the embossments having a height from about 350 μm to about 1,500 μm. Further embodiment comprise a product having a Percent Compressibility from about 1.5% to about 4.5%.

Claims
