Abstract
The purpose of this study was to determine the effects of stress during drying upon the strength of the paper.
This study consisted of two machine runs on a pilot paper machine. The machine was operated with minimum tension in all draws to provide a standard condition. For experimental conditions, tension was applied at various draws and increased until the sheet broke. Samples were taken from the standard condition sets and from-all experimental sets for evaluation purposes. The samples were evaluated for machine and cross-machine direction elongation, machine and cross-machine direction tensile, mullen, and machine and cross-machine direction tensile energy absorption.
It was observed that machine direction elongation decreased, the machine direction tensile strength increased, and the mullen decreased when increased tension was applied. The machine direction tensile energy absorption (T.E.A) decreased and the cross-machine direction T.E.A. increased when tension was applied to the drying paper.
