Abstract: Processes for pulping raw pulp material, such as wood chips, to provide pulp fibers having increased bulk, as well as bleaching the resulting pulp fibers to provide bleached pulp fibers having increased bulk. These pulp fibers and bleached pulp fibers may be incorporated into or used various products, such as multi-ply coated paperboards, fluff pulp, etc.

Abstract: A process comprising treating a lignocellulosic material preferably pulp in the presence of a transition metal catalyst with a oxidizing agent selected from a group consisting of hydrogen peroxide, hypochlorite, hypochlorous acid and any combination thereof to form a treated lignocellulosic material having a viscosity equal to or less than about 17 cp and having reducing functional groups selected from the group consisting of aldehyde and aldehyde type functional groups at the C6 and C1 positions but predominating at the C1 position.
