Strengthening of Paper Materials Under the Action of Unipolar Corona Discharge by Increasing the Level of Interaction Between Cellulose Fibers

摘要

The mechanical properties of bag paper before and after processing in a field of a unipolar (negative) corona discharge are investigated. It is shown that the modification of bag paper leads to its strengthening: absolute punching resistance, breaking stress, breaking length, tensile stiffness, tearing resistance in the longitudinal (machine) and transverse directions increase. The strengthening of the material is explained by the increased interfiber interaction due to an increase in the potential of the double electric layer on the surface of the fibers under the action of charge carriers injected into the paper volume during processing in a unipolar corona discharge.
