  • Method of applying chemical softening agents for making soft tissue
    Patent number: 6547925
    Abstract: An especially soft creped tissue can be produced by the indirect addition of chemical softening agents to the tissue web by applying the chemical softening agents to the surface of the Yankee dryer, such as by spraying. More specifically, the softening agents can be included as part of the creping adhesive formulation, which is sprayed onto the surface of the Yankee dryer between the creping blade and the pressure roll. The softening agents are subsequently transferred to the tissue sheet surface as the sheet is pressed against the Yankee dryer.
