  • Method for compressing structured tissues
    Patent number: 11981465
    Abstract: A method and apparatus are disclosed for processing structured tissue material to form a compressed bundle of folded tissues. A web of at least one ply of structured tissue is subjected to a destructuring operation before folding with itself or with another similar web to form a stack. The stack can then be compressed to form the compressed bundle at a pressure that is less than would have been the case, had the structured tissue not first been destructured.
    Type: Grant
    Filed: May 15, 2018
    Date of Patent: May 14, 2024
    Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLA

  • Tissue paper comprising pulp fibers originating from miscanthus and method for manufacturing the same
    Patent number: 10577748
    Abstract: A tissue paper web composed of one or more layers. At least one layer includes pulp fibers originating from at least one plant belonging to the genus Miscanthus wherein the pulp fibers are selected from chemical pulp fibers, mechanical pulp fibers subjected to a chemical pretreatment and mixtures thereof. The use of Miscanthus pulp fibers can lead to a major absolute increase in tensile strength along with good softness values.
