摘要： The present invention relates to paper that is produced by mixing bleached wood powder with natural wood pulp, thereby improving the dewaterability while reducing the amount of pulp used such that inexpensive and high-quality paper is provided. The wood material is subjected to a process in which it is milled and dried and is then sorted to smaller than a predetermined size and cleaned, the cleaned wood powder is bleached by being stirred for a predetermined time after having been introduced together with a bleaching agent, and the wood powder resulting from the bleaching is subjected to grinding processing and to a sorting and cleaning process, thereby producing bleached wood powder, and paper is produced by mixing from 5 to 20% by weight of the bleached wood powder with from 80 to 95% by weight of natural wood pulp and then subjecting the mixture to a paper-making process.

摘要： Tissue sheets are disclosed containing an additive composition. The additive composition is applied to the tissue sheet during a creping process in a controlled manner such that the additive composition forms deposits on the sheet separated by untreated areas. In one embodiment, the additive composition is applied to a creping surface. A wet tissue sheet is then transferred to the creping surface by a topographical surface containing elevations. The elevations press the tissue sheet against the creping surface. When creped from the surface, the additive compositions transfers to the tissue sheet according to where the elevations were located on the topographical surface.

摘要： A process for manufacturing fiberboard by preparing a fiber slurry mixture including containing cellulose fibers and water then atomizing a liquid bituminous material, such as asphalt. The liquid bituminous material is atomized by mixing it with a pressurized gas, such as compressed air, forming a mist comprising droplets of bituminous material having a diameter between 20 microns and 50 microns. A water spray solidifies the bituminous material droplets thereby forming bituminous particles which fall into the fiber slurry within the spray chamber. From there the slurry is sheared, dewatered, and dried, forming a finished fiberboard.
