  • Patent number: 6929714
    Abstract: A method for forming a tissue product that is soft and produces relatively low levels of slough is provided. The method includes providing a liquid furnish of cellulosic fibers and forming a multi-layered wet web therefrom. The web is dried (e.g., through-dried) to a solids consistency of 90% or greater. A latex having a glass transition temperature less than about 30° C. is applied to the dried web (e.g., foamed, printed, sprayed, etc.) such that the latex comprises less than about 3% by weight of the dry weight of the web. The latex remains substantially uncured after being applied to the dried web.

  • Patent number: 6572736
    Abstract: The non-woven web of the present invention is comprised of recycled cellulose fiber and untreated Clarifier Sludge, and optionally, recycled glass fiber. Unlike uses of reclaimed Clarifier Sludge whereby the material has been treated in some fashion to improve its quality, the non-woven web of the present invention utilizes untreated Clarifier Sludge. The Clarifier Sludge of the present invention is dry enough to handle, and in one example varies between about 30% and about 45% solids. The Clarifier Sludge can be added to web-forming equipment (e.g., papermaking equipment) either in a waste paper disintegrator or into a recycling apparatus (e.g., broke pulper) whose output is metered into a refiner tank of the web-forming equipment. In an embodiment utilizing a broke pulper for introduction of the Clarifier Sludge, the broke pulper is filled with clarifier sludge and water to a consistency of about 3.5% solids.

  • Patent number: 6547928
    Abstract: Disclosed is a composition for softening an absorbent tissue and tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; a bilayer disrupter and a high polymer. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. The high polymer adds “stringiness” to the composition opening the air pressure operating window for spray application of the softening composition.

  • Patent number: 6277241
    Abstract: The present invention is generally directed to base webs that are creped after a bonding material has been applied to at least one side of the web according to a predetermined pattern. The base web disclosed in the present application is made from at least three fibrous layers. The outer layers of the web contain synthetic staple fibers for increasing the tensile strength and abrasion resistant properties of the web. In one embodiment, the middle layer can further contain hardwood fibers, such as eucalyptus fibers, which improves the wipe dry properties of the web.

  • Patent number: 6207012
    Abstract: The invention relates to hydrophilic, humectant, soft, pliant, single-ply or multi-ply absorbent papers in the form of a towel. These humectant paper products are formed by supplying a furnish to headbox comprising: Cellulosic papermaking fiber consisting essentially of recycle fiber, hardwood fiber, softwood fiber, and mixtures thereof; and optionally up to 50% synthetic fibers and a softener which has a melting range of about 0°-40° C. wherein the softener comprises an imidazoline moiety formulated in organic compounds selected from the group consisting of alkoxylated aliphatic polyols, alkoxylated aliphatic diols, aliphatic polyols, aliphatic diols and a mixture of these compounds, wherein the process of adding the softener is controlled to retain a ratio of the average particle size of dispersed softener to the average fiber diameter in the range of about 0.01 to 15 percent: wet pressing said nascent web, creping said web from said Yankee, and recovering the paper products.
