  • Patent number: 7462257
    Abstract: A process for producing tissue webs is disclosed. The process may include the step of partially dewatering a tissue web, subjecting the web to at least one deflection against a fabric, such as a coarse fabric, and then creping the web. During the process, after being dewatered, the tissue web is transferred from a transfer conveyor to the fabric using a pneumatic force, such as a suction force. In order to prevent liquids from rewetting the tissue web as the tissue web is being transferred to the fabric, the transfer conveyor is made from a material that inhibits or prevents liquids from flowing into the tissue web. For instance, in one embodiment, the transfer conveyor may comprise a felt comprised of small capillary materials. The felt may have an intake rate, for instance, of less than about 150 ?L/s when wet, may have a mean free pore size of less than about 20 microns, and may have a minimum pore size of less than about 5 microns.

  • Patent number: 6709550
    Abstract: A multi-layered paper web that has increased strength for minimizing slough and lint is provided. In one embodiment, the paper web contains an outer layer formed from unrefined hardwood fibers and an inner layer formed from refined hardwood, softwood, and machine broke fibers. During formation within a headbox, the outer and inner fibrous layers are allowed to partially blend. By partially blending the layers, the fibers within each layer can form bonds in the −z direction to provide sufficient strength to minimize lint and slough.
