  • Patent number: 11268242
    Abstract: The invention relates to a method of transferring a tissue web with residual moisture to a Yankee cylinder and final removal of the dried tissue web from the Yankee cylinder using a doctor blade and collecting the dried web on a reel-up machine forming a tissue reel. The invention also relates to the Yankee adhesive composition per se. The method involves preparation of a water solution of a Yankee adhesive composition with less than 10% final solids content to be applied on the surface of the Yankee cylinder ahead of transferring the tissue web with residual moisture to the Yankee cylinder. The inventive method applies an aqueous PVOH solution with a very high molecular weight polyvinyl alcohol as a part of the solid content of the Yankee adhesive in an amount ranging from 20-65% of the final solids content of the Yankee adhesive. The aqueous PVOH solution with the very high molecular weight polyvinyl alcohol establish a viscosity ranging from 90 cP to 300 cP.
