Abstract
The present invention provides a durable tissue product produced from a tissue web that has been manufactured by applying a binder, such as by printing, to one side of the web and then contacting the binder applied side to a rotating dryer and creping the web therefrom. The side of the web opposite of the binder applied side is generally not treated with a binder, or the like, and is not subjected to creping. Further, the opposite side is generally formed from a layer of short, low coarseness cellulosic fibers, such as hardwood kraft fibers, and may be substantially free from long cellulosic fibers, such as softwood fibers. Despite forming the untreated surface from short fibers, the tissue product has good durability, such as a slough from about 6.0 to about 9.0 mg.
Claims11
A method of forming a durable multi-ply tissue product comprising the steps of:
- a. dispersing short, low coarseness pulp fibers in water to form a first fiber slurry;
- b. dispersing long pulp fibers in water to form a second fiber slurry;
- c. dispersing long pulp fibers in water form a third fiber slurry;
- d. depositing the first, second and third fiber slurries in a layered arrangement on a moving belt to form a multi-layered tissue web, wherein the first fiber slurry contacts the moving belt and forms a first outer surface of the web and the third fiber slurry contacts air and forms a second outer surface of the web and the second fiber slurry is disposed between the first and third fiber slurries;
- e. applying a binder to the second outer surface of the web according to a first preselected pattern;
- f. creping the second outer surface of the web after application of the binder;
- and
- g. converting the creped web into a tissue product wherein the first outer surface has a slough less than about 9.0 mg.
