摘要： A process for producing a creped sheet as well as a creping blade and creped paper product formed by such blade is set forth with the process including the steps of adhering a cellulosic web to a moving surface, providing a stepped creping blade disposed to crepe the cellulosic web from the moving surface and creping the cellulosic web from the moving surface forms a creped paper product having greater bulk and absorbency than previously prepared creped paper products. The stepped creping blade used in carrying out the process of the present invention includes an elongated body adapted to be engagable against, and span the width of, the moving surface, the elongated body having a cross section including a relief surface generally facing toward the moving surface, a back surface substantially parallel to the relief surface and generally facing away from the moving surface, a top surface adjacent both the relief surface and a recessed surface with the recessed surface being adjacent both the top surface and the back surface and forming a contact edge with the top surface such that the contact edge engages against the moving surface for creping the cellulosic web from the moving surface. The top surface and the recessed surface form a back step edge while the recessed surface and the back surface form a trailing edge. When utilizing such a blade configuration, the process further includes the steps of first contacting the cellulosic web conveyed by the moving surface with the contact edge, then optionally contacting the cellulosic web creped by the contact edge with the back step edge and subsequently contacting the cellulosic web creped by the contact edge with the trailing edge.

摘要： 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.

摘要： 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. The ply is embossed to an emboss depth of at least about 0.020 inch, the percent loss in total dry breaking tensile strength upon embossing of the tissue being no more than about 80% of the percent loss in total dry breaking tensile strength upon embossing plies of a comparable conventional water formed tissue. The ply includes a basis weight of from about 4 to about 20 pound per 3,000 sq. ft. ream.

摘要： A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas. A method of forming a multi-ply tissue involves conveying a base sheet through a nip between an impression roll and a pattern roll to produce an embossed base sheet having a back side possessing projections, applying adhesive to the back side of the embossed base sheet at spaced apart locations, and applying a flat backing sheet to the back side of the embossed base sheet so that the backing sheet adheres to the back side of the embossed base sheet at said spaced apart locations. A method of producing an embossed tissue involves successively conveying a base sheet through a nip between a first impression roll and a pattern roll, and conveying the base sheet through another nip between the pattern roll and a second impression roll, wherein the second impression roll is made of rubber having a lower hardness than the rubber from which the first impression roll is made.

摘要： Dispensable sheet material includes opposite side edges spaced apart from one another to define the overall width of the sheet material. Zones of weakness are spaced along the sheet material. Adjacent zones of weakness are spaced apart by a distance of from about 50% to about 200% of the overall width of the sheet material to divide the sheet material into a plurality of sheet material segments. Each of the zones of weakness comprises a plurality of perforations and frangible sheet material portions. Each of the frangible sheet material portions has a width of from about 0.3 mm to about 1.8 mm. The total width of the frangible sheet portions in each zone of weakness is from about 10% to about 30% of the overall width of the sheet material. The sheet material has an elasticity in the dispensing direction of from about 4% to about 20%. The sheet material has a dry tensile strength in the dispensing direction of from about 4,000 grams per 3 inches of width to about 12,000 grams per 3 inches of width. The sheet material has a wet tensile strength in the weakest direction, typically, a direction orthogonal to the dispensing direction, of at least about 900 grams per 3 inches of width. In addition, the sheet material has a tensile ratio of less than about 2.0. A dispensing system includes a dispenser defining an interior for containing the sheet material and an outlet for allowing sheet material to be dispensed from the interior of the housing.
