Tissue sheets having good strength and bulk
View Patent ↗A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a through drying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the through drying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the through drying fabric when the dried sheet is applied to the surface of the creping cylinder.
1. A tissue sheet having a geometric mean slope of from about 1.0 to about 3.5 kilograms of force per 3 inches of sample width, a geometric mean tensile strength of from about 400 to about 900 grams of force per 3 inches of sample width, a bulk of from about 13 to about 22 cubic centimeters per gram, and a Plate Stiffness of about 1.50 Newton-millimeters or less.
2. The tissue sheet of claim 1 having a Fuzz-On-Edge value of about 1.50 or greater.
3. The tissue sheet of claim 1 having a having a Pinhole Coverage Index of about 0.25 or less.
4. The tissue sheet of claim 1 having a having a Pinhole Count Index of about 65 or less.
5. The tissue sheet of claim 1 having a having a Pinhole Size Index of about 600 or less.
