  • TISSUE HAVING HIGH STRENGTH AND LOW MODULUS
    Publication number: 20140209262
    Abstract: The present invention provides tissue products having a high degree of stretch and low modulus at relatively high tensile strengths, such as geometric mean tensile strengths greater than about 1500 g/3? and more preferably greater than about 2000 g/3?. The combination of a tough, yet relatively supple sheet is preferably achieved by subjecting the embryonic web to a speed differential as it is passed from one fabric in the papermaking process to another, commonly referred to as rush transfer.
    Type: Application
