  • Publication number: 20110108224
    Abstract: The object of the invention is to provide a papermaking felt which can be easily engaged in a papermaking machine, wherein the work time for engaging the felt is short, the initial warming-up period until reaching the highest papermaking speed is short, and the felt life is long. This object is achieved by integrating and attaching by dispersion in the batt layer of the felt a polymeric elastomer having high deformability when pressure is applied and good recoverability after pressure is applied. When said polymeric elastomer is in the form of a film and when measured at a room temperature of 20° C. and a relative humidity of 65%, the 100% modulus value of the film is 1 to 100 kg/cm2, the residual strain after 100% elongation is 30% or less, and the attached amount of polymeric elastomers is 0.5 to 20 wt. % of the papermaking press felt weight. Examples of materials include polyurethane elastomers, polyethylene elastomers, styrene-butadiene rubber, silicone rubber, or the like.

    Abstract: A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a throughdrying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the throughdrying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the throughdrying fabric when the dried sheet is applied to the surface of the creping cylinder.

    Abstract: A process for improving optical properties of high-yield pulp (HYP) for producing paper products with superior brightness. Optical brightening agents (OBAs) can effectively improve the optical properties of high-yield pulp (HYP). The present process involves incorporating the OBAs into the alkaline peroxide bleaching process. By combining peroxide bleaching with an optical brightening agent, one can decrease the bleaching cost to reach the same brightness target. Some key advantages of adding OBA to HYP at the pulp mill over the conventional wet-end addition of OBA include: i) the quenching effect on OBA by the wet-end cationic polymers such as PEI is decreased by fixing OBA on HYP fibers; ii) the negative impact of metal ions in the white water system on the OBA performance is minimized when OBA is pre-adsorbed and fixed on HYP fibers; iii) the photo-yellowing (color reversion) of HYP and HYP-containing paper sheets is decreased when more OBA is on HYP fibers to protect them from harmful UV radiation.

    Abstract: The present invention aims to provide cellulose-based fibrous materials for obtaining papers and sheets having low density, high surface quality, good size stability despite of high strength, and high opacity. Cellulose-based fibrous materials having external fibrils consisting of an assembly of scale-like microfibrils exhibit a higher fiber stiffness, a lower water retention value and a higher specific surface area as compared with fibrous materials having filamentous external fibrils at the same freeness. Papers and sheets having low density, high surface quality, good size stability and high opacity can be obtained by using such fibrous materials.

  • Publication number: 20090028373
    Abstract: The production equipment of paper-made components for loudspeakers includes a mixing device, a fining device, a paper-making device, and a shape processing device. The mixing device mixes material of a paper-made component for a loudspeaker into liquid to generate mixed liquid. The fining device includes a pressure unit, an orifice, and an inner wall. The pressure unit applies pressure on the mixed liquid to cause the mixed liquid to pass through the orifice, and the mixed liquid collides against the inner wall to cause the fining device to generate fined material. The paper-making device paper-makes the fined material to generate a paper-made component. The shape processing device processes the shape of the paper-made component. This structure provides production equipment of the paper-made components for loudspeakers, which prepares material for paper-making in a short time and reduces producing time.
