Estimating the term…
Soft throughdried tissues, which are sufficiently soft to serve as premium bathroom tissues, can be made without the use of a Yankee dryer. The typical Yankee functions of building machine direction and cross-machine direction stretch are replaced by a wet end rush transfer and the throughdrying fabric design, respectively. It is particularly advantageous to form the tissue with chemimechanically treated fibers in at least one layer. The resulting tissues have high bulk (about 6 cubic centimeters per gram or greater) and low stiffness.
A soft tissue product comprising one or more throughdried tissue plies having a MD Max Slope of about 10 or less and a relatively uniform density.
A soft tissue product comprising one or more uncreped throughdried tissue plies having a MD Max Slope of about 10 or less and a relatively uniform density, wherein said uncreped throughdried tissue plies are uncreped throughdried tissue sheets which were dried on a throughdrying fabric and have a three-dimensional surface topology corresponding to the surface of the throughdrying fabric.
A soft tissue product comprising one or more throughdried tissue plies having a MD Stiffness Factor of about 150 or less and a relatively uniform density.
A soft tissue product comprising one or more uncreped throughdried tissue plies having a MD Stiffness Factor of about 150 or less and a relatively uniform density, wherein said uncreped throughdried tissue plies are uncreped throughdried tissue sheets which are dried on a throughdrying fabric and have a three-dimensional surface topology corresponding to the surface of the throughdrying fabric.
