Multi-ply tissue product produced from a single ply tissue web
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.

STAINABLE DECORATIVE SHEET AND METHOD OF STAINING DECORATIVE SHEET
A stainable decorative sheet having good adhesion between a paper base material and a nonwoven fabric with a surface excellent in tactile sensation and stainability, excellent transparency, and a method for coloring the stainable decorative sheet. The stainable decorative sheet includes a paper base material, an adhesive layer, a nonwoven fabric layer, and a transparency improving layer in a predetermined structure, wherein the nonwoven fabric layer partially has a filling part A and a filling part B in a part of voids among fibers of the nonwoven fabric layer.
TISSUE PRODUCTS COMPRISING CROSSLINKED FIBERS
The present disclosure relates to tissue products comprising crosslinked fibers. The tissue products generally have good formation, such as a Formation Index greater than about 20, strength, such as geometric mean tensile strengths greater than about 700 g/3″ and high bulk, such as sheet bulks greater than about 10 cc/g. Unlike many prior art crosslinked fibers, the crosslinked softwood pulps of the present invention, which are preferably prepared using a glyoxal based crosslinking reagent, are readily dispersible in water and have relatively low degrees of kink and curl. As such, the fibers are well suited for forming wet-laid tissue products and more particularly wet-laid tissue products having improved physical properties, such as improved bulk.

MULTILAYER FILM COMPRISING HIGHLY REFINED CELLULOSE FIBERS
The present invention relates to a method for manufacturing a multilayer film comprising highly refined cellulose fibers, the method comprising the steps of: a) forming a first wet web by applying a first pulp suspension comprising highly refined cellulose fibers on a first wire; b) partially dewatering the first wet web to obtain a first partially dewatered web; c) forming a second wet web by applying a second pulp suspension comprising highly refined cellulose fibers on a second wire; d) partially dewatering the second wet web to obtain a second partially dewatered web; e) joining the first and second partially dewatered web to obtain a multilayer web; and f) further dewatering, and optionally drying, the multilayer web to obtain a multilayer film comprising highly refined cellulose fibers; wherein at least one of said first and second pulp suspension comprises lignin at a concentration in the range of 0.1-50 wt %, based on the total dry weight of the pulp suspension.
