摘要： A pulp in accordance with a particular embodiment includes crosslinked cellulose fibers. The pulp can have high brightness, reactivity, and intrinsic viscosity. The pulp, therefore, can be well suited for use as a precursor in the production of low-color, high-viscosity cellulose derivatives. A method in accordance with a particular embodiment of the present technology includes forming a pulp from a cellulosic feedstock, bleaching the pulp, crosslinking cellulose fibers within the pulp while the pulp has a high consistency, and drying the pulp. The bleaching process can reduce a lignin content of the pulp to less than or equal to 0.09% by oven-dried weight of the crosslinked cellulose fibers. Crosslinking the cellulose fibers can include exposing the cellulose fibers to a glycidyl ether crosslinker having two or more glycidyl groups and a molecular weight per epoxide within a range from 140 to 175.

摘要： A water-dispersible sheet and a cigarette using the sheet are disclosed. The sheet comprises a water-resolvable base paper made from fibrous raw materials and a water-dispersible coating layer containing water-soluble polymer and an alkaline compound. The sheet is also produced through an impregnation treatment for a water-resolvable base paper with a coating mixture containing water-soluble polymer and an alkaline compound, wherein said water-resolvable base paper is made from a mixture of water-dispersible fibers and fibrous carboxymethyl cellulose acid or fibrous carboxyethyl cellulose acid. The gas-permeability of the water-dispersible sheet is controlled by the water-dispersible coating layer or the impregnation treatment.

摘要： A label assembly including one or more dissolvable thermal direct adhesive labels and methods of assembly and use. According to one embodiment, each label includes a base layer, a thermal direct layer, an adhesive layer, and a barrier layer. The base layer, which has an upper surface and a lower surface, is water-dissolvable and may be made of a water-dissolvable paper. The thermal direct layer is positioned directly over the upper surface of the base layer and functions in the conventional manner to produce markings therein in response to heat. The adhesive layer is water-dissolvable and is positioned below the lower surface of the base layer. The barrier layer, which is positioned directly below the lower surface of the base layer and directly over the adhesive layer, serves to prevent migration of the adhesive layer through the base layer and into contact with the thermal direct layer.

摘要： Pulps in accordance with certain embodiments include crosslinked cellulose fibers and have high brightness, reactivity, and intrinsic viscosity, and therefore can be well suited for use as a precursor in the production of low-color, high-viscosity cellulose derivatives. A method in accordance with the present technology includes forming a pulp from a cellulosic feedstock, bleaching the pulp, crosslinking cellulose fibers within the pulp while the pulp has a high consistency, and drying the pulp. Crosslinking the cellulose fibers can include exposing the fibers to a glycidyl ether crosslinker having two or more glycidyl groups and a molecular weight per epoxide within a range from 140 to 175. Another method in accordance with the present technology includes providing an aqueous suspension of pulp that includes chemical wood pulp fibers that were previously bleached and dried, crosslinking the fibers with such a glycidal ether crosslinker, and drying the pulp.

摘要： The present invention relates to a method for manufacturing an intermediate product that can be stored and transported and efficiently converted into microfibrillated cellulose with limited energy input at the time of conversion. More specifically, the invention involves the use of dewatered carboxymethylcellulose or carboxylated cellulose fiber having a low degree of substitution and a high amount of additives.
