  • Patent number: 10626557
    Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85° after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.

  • Patent number: 8444807
    Abstract: The invention relates to a method for preparing paper pulp from recycled paper containing contaminants characterized in that it comprises a first step of agitating the paper in the presence of water in order to obtain a mixture of fibers and contaminants in suspension, a second step of coarsely screening said mixture in order to separate the coarse contaminants from the rest of the suspension, a third step of fine screening in order to separate the fine contaminants from the coarsely-screened suspension and a fourth step of washing said coarse and fine contaminants in order to separate the reusable fibrous materials from the rest of the non-reusable contaminants. In particular, the invention aims to provide a method for preparing paper pulp that is capable of producing a good quality paper pulp from highly-contaminated recycled paper, especially having a contaminant level in the dry state that is greater than or equal to 15% by weight.
