Multi-ply cellulosic products using high-bulk cellulosic fibers

   
   

A multi-ply paperboard comprising at least one ply of conventional cellulose fibers and from about 0.1 to about 6 weight percent of a water-borne binding agent; and at least one ply of chemically intrafiber crosslinked cellulosic high-bulk fibers and from about 0.1 to about 6 weight percent of a water-borne binding agent. The water-borne binding agent may be a starch, a modified starch, a polyvinyl alcohol, a polyvinyl acetate, a polyethylene/acrylic acid copolymer, an acrylic acid polymer, a polyacrylate, a polyacrylamide, a polyamine, guar gum, an oxidized polyethylene, a polyvinyl chloride, a polyvinyl chloride/acrylic acid copolymer, an acrylonitrile/butadiene/styrene copolymer or polyacrylonitrile. A method for making the paperboard is disclosed.

Una cartulina multi-ply que abarca por lo menos una capa de fibras convencionales de la celulosa y de cerca de 0.1 a los por ciento de cerca de 6 pesos de un agente astringente flotante; y por lo menos una capa químicamente de intrafiber reticuló fibras celulósicas del alto-bulto y de cerca de 0.1 a los por ciento de cerca de 6 pesos de un agente astringente flotante. El agente astringente flotante puede ser un almidón, un almidón modificado, un alcohol de polivinilo, un acetato polivinilo, un copolímero ácido de polyethylene/acrylic, un polímero ácido de acrílico, un polyacrylate, un polyacrylamide, un polyamine, goma del guar, un polietileno oxidado, un cloruro de polivinilo, un copolímero ácido polivinilo de chloride/acrylic, un copolímero de acrylonitrile/butadiene/styrene o polyacrylonitrile. Un método para hacer la cartulina se divulga.
