Abstract
The present invention provides multi-ply creped tissue products, and in particular embodiments creped wet-pressed tissue products, having substantially higher per-ply basis weights, such as from about 14.0 grams per square meter or greater. Despite having relatively high per-ply basis weights, the products are generally soft and flexible, such as having a softness value (measured as TS7) less than about 10.0 and a Stiffness Index less than about 20.0. While being soft and flexible, the tissue products are durable enough to withstand use, such as having a geometric mean tensile (GMT) greater than about 1,000 g/3″.
Claims15
A method of producing a creped tissue product comprising the steps of:
- a. dispersing a plurality of first cellulosic fibers to form a first fiber slurry;
- b. disposing the first fiber slurry on a forming fabric to form a wet tissue web;
- c. partially dewatering the wet tissue web;
- d. providing a creping composition comprising a water-soluble adhesive and a water-soluble release agent, wherein the ratio of adhesive agent to release agent (on a mass basis) is from about 1.5:1 to about 0.75:1;
- e. providing a dryer having a dryer surface and a dryer surface area;
- f. applying the creping composition to the dryer surface wherein the creping composition add-on ranges from about 8.0 to about 12.0 mg per square meter of dryer surface area;
- g. pressing the partially dewatered tissue web to the dryer surface;
- h. drying the tissue web;
- i. creping the dried tissue web from the dryer surface to yield a creped, wet-pressed tissue ply;
- j. topically apply a softening composition to at least one creped, wet-pressed tissue ply;
- and
- k. plying three creped, wet-pressed tissue plies together to a form a three-ply tissue product.
