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 uncreped throughdried tissue plies and having a MD Max Slope of about 10 or less.
A soft tissue product comprising one or more uncreped throughdried tissue plies and having a MD Stiffness Factor of about 150 or less.
A soft single-ply bath tissue comprising a layered, uncreped throughdried tissue sheet having an air side layer comprising about 80 weight percent or greater curled eucalyptus fibers and a fabric side layer comprising about 80 weight percent or greater curled eucalyptus fibers, said tissue having a Bulk of from about 9 to about 20 cubic centimeters per gram, a MD Stiffness Factor of from about 50 to about 100, and a machine direction stretch of from about 10 to about 25 percent.
A soft tissue product comprising one or more tissue plies and having a Bulk of 9.8 cubic centimeters per gram or greater and a MD Max Slope of about 10 or less.
A soft tissue product comprising one or more tissue plies having a Bulk of 9.8 cubic centimeters per gram or greater and a MD Stiffness Factor of about 150 or less.
A soft tissue product comprising one or more uncreped throughdried tissue plies and having a Bulk of 9.8 cubic centimeters per gram or greater and a MD Max Slope of about 10 or less.
A soft tissue product comprising one or more uncreped throughdried tissue plies and having a Bulk of 9.8 cubic centimeters per gram or greater and a MD Stiffness Factor of about 150 or less.
