    Abstract: An improved processes for making fluff pulp sheets mechanically eliminates many of the unwanted fiber-to-fiber bonding (fiber bundles) which may be contained in the sheet to produce consistent and uniform quality fluff pulp. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break a majority of fiber bundles contained in the web. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. A shoe press can be used to dewater the web after it is subjected to the pulsating shear forces. The web can be dried utilizing conventional drying equipment, such as cylindrical driers.

  • Patent number: 8864945
    Abstract: A method of making a multi-ply wiper/towel product with cellulosic microfibers. The method includes compactively dewatering a nascent web that includes at least about 10% fibrillated cellulosic microfibers and has an apparently random distribution of fibers. The dewatered web having the apparently random distribution of fibers is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the belt. The belt-creping step occurs under pressure in a belt creping nip defined between the transfer surface and the creping belt. The web is dried to form a dried web that includes a plurality of fiber-enriched hollow domed regions protruding from an upper side of the dried web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof.

  • Patent number: 8852398
    Abstract: The present invention provides tissue products having increased CD stretch, which may be manufactured using a process in which the nascent web is subjected to two distinct rush transfers. The first rush transfer occurs when the web is transferred from the forming fabric to the transfer fabric, i.e., the “first position,” and the second occurs when the web is transferred from the transfer fabric to the through-air drying fabric (TAD) fabric, i.e., the “second position.” The overall speed differential between the forming fabric and the TAD fabric may be, for example, from about 10 to about 50 percent, with the amount of rush transfer being divided between the first and second position in a manner sufficient to achieve the desired CD stretch and other sheet properties.

  • Patent number: 8834677
    Abstract: The present invention provides tissue products having an MD/CD Tensile Ratio less than about 0.95, yet relatively high geometric tensile strength, such as geometric mean tensile strengths greater than about 1500 g/3? and more preferably greater than about 2000 g/3?. The combination of a tough, yet relatively supple sheet is preferably achieved by subjecting the embryonic web to a speed differential as it is passed from one fabric in the papermaking process to another, commonly referred to as rush transfer.

  • Patent number: 8834678
    Abstract: The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. The tissue products also have a sizing agent that increases the Wet Out time, without negatively impacting softness or machine runability. Preferably the creping composition comprises a cationic component and a film forming component, both of which are preferably water soluble. The cationic component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained on the sheet. The overall retention of the creping composition on the sheet reduces the concentration of the composition in the machine process water, improving machine operability and runability.

  • Publication number: 20140238629
    Abstract: Systems and methods for forming fiber webs, including those suitable for use as filter media and battery separators, are provided. In some embodiments, the systems and methods involve designs which allow improved control of the fiber web forming process. For example, in certain embodiments involving the flowing of more than one fiber mixtures, the amount of mixing of the fiber mixtures may be controlled to produce fiber webs having different structural and/or performance characteristics. In some embodiments, the systems and methods can be used to form fiber webs having a gradient in a property across a portion of, or the entire, thickness of the fiber web.

  • Patent number: 8790494
    Abstract: The invention provides a three layered reprographic paper having improved strength, stiffness and curl resistance properties, and a method for making same. The paper has a central core layer made largely of cellulose and bulked with a bulking agent such as a diamide salt. A starch-based metered size press coating is pressed on both sides of the core layer, wherein the starch has a high solid content. The coating forms a three layered paper having an I-beam arrangement with high strength outer layers surrounding a low density core.
