    摘要： A foam-formed nonlaminated stratified paper tissue 300 and method of making the same includes a first zone 301 of foam-formed paper tissue formed from a furnish which is relatively rich in hardwood fiber. A second zone 401 of foam-formed paper tissue is formed from a furnish which is relatively rich in softwood fiber. The second zone is formed unitary and entangled with the first zone to form a nonlaminated stratified paper tissue. A high softness integument is defined adjacent to an outer surface of the first zone and a substratum is defined adjacent to a surface of the second zone spaced away from the integument. The integument 320 on the outer surface of the first zone includes an enriched region 330 wherein the hardwood fiber content is greater than that obtainable in the corresponding region of a tissue obtained from furnishes having the same compositions under the same conditions but employing water-forming instead of foam-forming. The substratum 420 on the surface of the second zone includes a region enriched in softwood fiber. The enriched region 430 of substantially pure hardwood fiber provides an extremely soft and smooth surface as detected by human somatic sensibility.

    摘要： Apparatus and method for the manufacture of a non-woven fibrous web such as paper from a dispersion of fibers in a foamed liquid in which fiber fumish in a foamed liquid comprising a solution of surfactant in water is discharged from a headbox into the nip of a twin forming wire prior to its passage over a forming roll. The watersurfactant solution is drained from the web and recycled as a foamed liquid containing about 65 % air in the form of bubbles of from about 20 to about 200 microns in diameter. The foamed liquid is directed into a mix tank wherein a slurry containing fibers at 20 % to 55 % solids is added and mixed. The slurry is pumped to the headbox and into the nip of the forming wires.

    摘要： A method of foam forming of paper includes the steps of metering to a dewatering device a controlled feed of fiber dispersed in an aqueous liquid wherein the consistency of the fiber dispersed in the liquid is between about 0.5 and about 7% by weight recovering from the dewatering device a uniform continuous strand of between about 8 and 30% by weight; introducing a stream of a foamed aqueous admixture and the continuous strand of semi-moist pulp into a dispersing mixer having shearing action extending substantially throughout a zone substantially athwart the flow path of the uniform continuous strand and the foamed aqueous stream, to form a stream of dispersed fiber bearing aqueous foam; conducting the dispersed fiber bearing aqueous foam stream to the inlet of a positive displacement pump and thence through a headbox, and depositing the fibers on a moving foraminous support to form the paper.

    摘要： A foam-formed tissue ply is provided which is compacted, e.g. by embossing or calendering, to a percentage reduction in caliper of at least about 10% over at least about 10% of its area and in the thus compacted form exhibits a strength and/or softness which is superior to that of a correspondingly compacted like ply of a comparable water formed tissue having the same structure, overall fiber composition, basis weight and strength when in the uncompacted state.
