In general, the present invention is directed to a process for producing multi-ply tissue products from a single ply tissue web and the resulting multi-ply products, which have good softness and strength characteristics. The process of the present invention generally involves producing a first single ply tissue web and then splitting the web into two separate single ply tissue webs that can be converted into a multi-ply web. In certain preferred embodiments the single ply web may be manufactured such that when it is split into two separate webs the two webs are substantially identical.

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.

A wrapper according to an aspect includes a pulp layer and metal particles uniformly distributed inside the pulp layer, wherein the metal particles contain a metal flake paste.

The present disclosure describes a treated cellulosic material comprising a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising a polymer, the polymer comprising a polyurethane polymer. The present disclosure further describes a method for preparing a treated cellulosic material comprising providing a cellulosic material; and a first treatment protocol comprising impregnating the cellulosic material with an aqueous dispersion comprising a polymer, the polymer comprising a polyurethane polymer; and a second treatment protocol comprising impregnating the cellulosic material with a modifying agent, the modifying agent comprising a hydrophobic amine.

A method for manufacturing a fibrous web, such as web of paper, board, tissue or the like is disclosed. The method includes obtaining at least one fibre suspension of lignocellulosic and/or cellulosic fibres and feeding the fibre suspension into an intermediate residence entity. The fibre suspension including bacterial endospores, is discharged out of the intermediate residence entity via an outlet after a residence time of at least 2 hours in the intermediate residence entity and after a time delay the fibre suspension is formed into a fibrous web. Bacterial endospores are sensitized by adding a germinant surfactant including a primary or secondary ammonium head group and a linear unsubstituted C12-alkyl tail, to the fibre suspension at an addition point located at a lower part of the intermediate residence entity or after the outlet of the intermediate residence entity, but before the formation of the fibrous web.

A composition is disclosed that may include an adhesive agent and a release aid. A Yankee dryer coating is also disclosed that may include a release aid. The release aid may include a cationic polymer salt that is a reaction product of a polyamine or a polyalkyleneimine and a substituted alkyl trialkyl quaternary ammonium salt. Also provided are methods of treating and creping paper.
