  • Patent number: 5885415
    Abstract: The present invention relates to biaxially undulatory single-ply and multi-ply tissues, single-ply and multi-ply towels, single-ply and multi-ply napkins and other personal care and cleaning products as well as novel creping blades and novel processes for the manufacture of such paper products. The present invention is directed to tissue and towel product having highly desirable bulk, appearance and softness characteristics produced by utilizing a novel undulatory creping blade having a multiplicity of serrulations formed in its rake surface which presents differentiated creping angles and/or rake angles to the web as it is being creped. The invention is also directed to a novel blade having an undulatory rake surface having trough-shaped serrulations in the rake surface of the blade. The undulatory creping blade has a multiplicity of alternating serrulated sections of either uniform depth or a multiplicity of arrays of serrulations having non-uniform depth.

  • Patent number: 5882479
    Abstract: A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particularly, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the funish sources being combined, and further, optionally adding the softener to the nascent web.

  • Patent number: 5409572
    Abstract: A single or multi-ply tissue product includes at least one foam-formed ply incorporating at least about 100 ppm of forming-loop-incorporated surfactant, the ply includes from at least about 50% by weight to about 80% by weight of relatively short, high softness cellulosic fiber formed by chemical pulping of hardwood. The fibers have a weight average fiber length of between about 0.5 to about 2.2 mm, a coarseness of about 7 to about 14 mg of fiber per 100 m of fiber length (mg/100 m). The ply includes from at least about 20% by weight to about 50% by weight of relatively long strength-enhancing cellulosic fiber chosen from chemically pulped softwood fiber and chemi-thermo-mechanically pulped softwood fiber and mixtures thereof. The strength-enhancing cellulosic fiber have a weight average fiber length of about 2 to about 4 mm, a coarseness of about 14 to about 28 mg/100 m. Optionally, up to about 30% by weight of bulk-enhancing fibers having a three-dimensional anfractuous character may be provided.

  • Patent number: 5164045
    Abstract: A foam-formed nonlaminated stratified paper tissue includes a first layer of bulky anfractuous fiber blend and a second layer of fiber blend having enhanced softness and caliper as compared to a conventional tissue of equivalent basis weight and strength. In a preferred embodiment, the first layer is a fiber blend of a bulky anfractuous fiber and a chemithermomechanical pulp. A method of forming a foam-formed nonlaminated stratified web of paper tissue material includes supplying a first furnish of a bulky anfractuous fiber blend directly to a foraminous support member. A second furnish of fiber blend is supplied onto the first furnish disposed on the foraminous support member. The furnishes may also be supplied in reverse order depending upon the forming configuration of the machine used. The first and second furnishes form a web of paper tissue material which is dried in a drying device to a predetermined dryness.

  • Patent number: 5087324
    Abstract: A delaminated stratified paper towel includes a dense first layer of chemical fiber blend and a second layer of a bulky anfractuous fiber blend unitary with the first layer. The first and second layers enhance a rate of absorption and water holding capacity of the paper towel. In a preferred embodiment, the second layer is a fiber blend having a high bulk softwood fiber and a chemi-thermomechanical pulp. A method of forming a delaminated stratified web of paper towel material includes supplying a first furnish directly to a wire and supplying a second furnish of a bulky anfractuous fiber blend directly onto the first furnish disposed on the wire. Drying the first and second furnishes forms a web of paper towel material having a predetermined dryness. The web of paper towel material is thereafter creped off of the drying device and embossed to a predetermined emboss depth. The web of paper towel material has an enhanced rate of absorption and water holding capacity.
