Throughdried tissue products such as facial tissue, bath tissue, and paper towels are made using a throughdrying fabric having from about 5 to about 300 machine direction impression knuckles per square inch (per 6.45 square centimeters) which are raised above the plane of the fabric. These impression knuckles create corresponding protrusions in the throughdried sheet which impart a significant amount of cross-machine direction stretch to the sheet. In addition, other properties such as bulk, absorbent capacity, absorbent rate and flexibility are also improved.
An uncreped throughdried tissue sheet having substantially uniform density, a basis weight of from about 10 to about 70 grams per square meter, a Wet Compressed Bulk (WCB) of about 4.5 or greater, an Absorbent Capacity of about 9 grams per gram or greater, a cross-machine direction stretch of about
An uncreped throughdried tissue sheet having substantially uniform density, a basis weight of from about 10 to about 70 grams per square meter, a Wet Compressed Bulk (WCB) of about 4.5 or greater, an Absorbent Capacity of about 9 grams per gram or greater, a cross-machine direction stretch of about 9 percent or greater and from about 5 to about 300 protrusions per square inch having a height relative to the surface plane of the sheet, as measured in an uncalendered state of about 0.005 inch or greater and which correspond to elongated machine-direction knuckles on the throughdrying fabric.
