Abstract

Official abstract text for this publication.

Fibrous structures having pillows and knuckles, wherein the fibrous structures contain two or more pillows that exhibit differential pillow height and methods for making same are provided.

First claim

Opening claim text (preview).

What is claimed is: 1. A fibrous structure comprising a first pillow exhibiting a first height and a second pillow exhibiting a second height wherein the first height is at least 50% greater than the second height, wherein the first pillow exhibits a bulk building capability of at least 20% of the bulk building capability of the second pillow. 2. The fibrous structure according to claim 1 wherein the first height is at least 60% greater than the second height. 3. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Dry Recoverability of greater than 1.00 as measured according to the Dry Compressive Modulus Test Method. 4. The fibrous structure according to claim 1 wherein the first pillow exhibits a bulk building capability of greater than 16 cc/g. 5. The fibrous structure according to claim 4 wherein the first pillow exhibits a bulk building capability of greater than 17 cc/g. 6. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a wet caliper normalized for basis weight of greater than 0.65 mils/(lb./3000 ft 2 ) as measured according to the Caliper Test Method. 7. The fibrous structure according to claim 1 wherein the fibrous structure is in roll form such that the roll of fibrous structure exhibits a Roll Compressibility of from about 0.5% to about 15% as measured according to the Roll Compressibility Test Method. 8. The fibrous structure according to claim 1 wherein the fibrous structure is in roll form such that the roll of fibrous structure exhibits a Roll Firmness of from about 2.5 mm to about 15 mm as measured according to the Roll Firmness Test Method. 9. The fibrous structure according to claim 1 wherein the fibrous structure is in roll form such that the roll of fibrous structure exhibits a Roll Compressibility of from about 0.5% to about 15% as measured according to the Roll Compressibility Test Method, a roll bulk of about 4 cm 3 /g to about 30 cm 3 /g, and a Roll Firmness of from about 2.5 mm to about 15 mm as measured according to the Roll Firmness Test Method.
