METHOD FOR DETERMINATION OF AN IRREVERSIBLE STRETCH AND OF ADYNAMIC MODULUS OF ELASTICITY |
摘要 |
The invention concerns a method for determination of an irreversible stretch and of a dynamic modulus of elasticity from a paper web (W). In the method, the irreversible stretch and the dynamic modulus of elasticity are determined from the paper web (W) by means of on-line measurement. The invention also concerns a method in which the quantities that have been determined are employed in the control of the papermaking process.
