  • Patent number: 6573203
    Abstract: The present invention may provide a towel desirably including first and second layers having cellulosic fibers and a repellant agent. The first and second layers may substantially sandwich a third layer having cellulosic fibers with higher absorbency than the first and second layers. All three layers may form a single ply.

  • Publication number: 20020139494
    Abstract: A process of recovering a useful population of fibers and fines from the waste stream of fiber processing facility is disclosed. Steam explosion of the fiber-containing waste stream is used to increase the separation efficiency of the fibers from the ash. The steam explosion also enhances the quality of the recovered fibers and fines, providing a population of recovered fibers which can be incorporated into the fiber component of a tissue or absorbent paper product.

  • Publication number: 20020084046
    Abstract: The present invention includes a process for making paper. The process may include the steps of providing pulp fibers in a chest and adding an enzymatic material to the pulp fibers at a storing stage for decreasing cellulose crystals. Furthermore, the process may include adding a strength agent to the pulp fibers at the storing stage.

  • Patent number: 6387210
    Abstract: A method of making sanitary paper products from coarse fibers. The method includes the steps of: (a) pulping coarse fibers in water with agitation to produce a pulp slurry, the pulp from the coarse fibers having an average fines content of greater than about 40%; (b) using an effective amount of pulp washing to reduce the fines content and increase the Canadian Standard Freeness; (c) introducing the pulp at a papermaking consistency into the headbox of a paper making machine; and (d) utilizing the pulp in a paper making process to produce sanitary paper products.

  • Patent number: 6332952
    Abstract: A toilet tissue product may include a first cellulosic ply and a second cellulosic ply. Desirably, the first cellulosic ply further includes a single layer and the second cellulosic ply further includes a single layer. At least one ply may have a region that prevents fluid from striking through the tissue product.

  • Patent number: 6296736
    Abstract: A method of making sanitary paper products from recycled newspapers. The method includes the steps of: (a) pulping newspapers in water with agitation to produce a pulp slurry, the pulp from the newspapers having an average fines content of greater than about 40% and a Canadian Standard Freeness of less than about 250; (b) washing the pulp, whereby the fines content is reduced to less than about 35% and the Canadian Standard Freeness is increased to more than about 300; (c) introducing the treated pulp at a papermaking consistency into the headbox of a paper making machine; (d) adding from about 0.01% to about 1.5% of a surfactant system to the treated pulp; and (e) utilizing the treated pulp in a paper making process to produce sanitary paper products.

  • Patent number: 6074527
    Abstract: The present invention encompasses a sanitary paper product including a wet-laid, surfactant treated nonwoven fibrous structure including coarse pulp fibers at least a portion contain oil and having a lower cup crush load and energy than an identical fibrous structure lacking the surfactant treatment.

  • Patent number: 6001218
    Abstract: A method of making sanitary paper products from newspapers. The method includes the steps of: (a) pulping newspapers in water with agitation to produce a pulp slurry, the fiber in the newspapers having an oil content ranging from about 0.025% to about 2.0%, by weight, and the slurry having a consistency between about 3% and about 18% and a pH below about 8.0; (b) adding a surfactant to the pulp slurry and maintaining the pulp slurry at a temperature above about 100.degree. F. for at least 15 minutes such that a substantial quantity of the oil in the old newspaper is retained; (c) increasing the consistency of the slurry to between about 3.5% and about 18%; and (d) using the treated pulp as a source of fibers in a paper making process to produce sanitary paper products.
