摘要： The formation of wet-pressed tissue webs useful for facial tissue, bath tissue, paper towels or the like is substantially improved by forming the wet tissue web in layers in which the second-formed layer has a consistency which is significantly less than the consistency of the first-formed layer. The fiber support index of the forming fabric is about 170 or greater. The resulting improvement in web formation enables uniform debonding during creping, which in turn provides a significant improvement in softness and a reduction in linting. Wet-pressed tissues made with this process are uniformly internally debonded, as measured by a high Void Volume Index, which is comparable to that of throughdried tissues.

摘要： The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.

摘要： A method of making absorbent cellulosic sheet with increased wet/dry CD tensile ratio includes treating the fiber at high consistency with debonder in a pulper, for example. The process enables the use of large amounts of debonder in a wet-press process in order to achieve wet/dry CD tensile ratios of greater than 30%.

摘要： Fibrous cellulosic products incorporating both conventional cellulosic fibers and laterally expanded cellulose fibers exhibit exceptional porosity, bulk, absorbency and resiliency properties. Typical products include absorbent tissue products, absorbent fluff products and flat papers. The laterally expanded cellulose fibers exhibit: (i) a broadened X-Ray diffraction peak for the most prominent reflection having a width at half-height, (W1/2h)A, of at least about 3.0° 2Θ, (ii) broad overlapping maxima in their Raman spectrum between 285 and 500 cm−1, the height of the two tallest of said maxima in said spectrum between 285 and 500 cm−1 being between 35 and 50% of the height of the peak near 1098 cm−1 and (iii) a blue stain when treated with Graff C-stain, the stain exhibiting less red than the stains exhibited with bleached hardwood kraft fibers and bleached softwood kraft fibers.

摘要： A process for making absorbent sheet includes: (a) depositing an aqueous furnish of cellulosic fiber on a forming fabric; (b) dewatering the wet web to a consistency of from about 15 to about 40 percent; (c) transferring the dewatered web from the forming fabric to another fabric traveling at a speed of from about 10 to about 80 percent slower than the forming fabric; (d) wet-shaping the web on an impression fabric whereby the web is macroscopically rearranged to conform to the surface of the impression fabric; and (e) impingement air drying the web. The process is particularly suitable for making high bulk products form difficult to process furnishes such as recycle furnishes and for making high basis weight products without compressive dewatering with a papermaking felt.
