Abstract
This senior engineering design project studies the effect of increased steel roll temperature and increased sheet moisture on the supercalendering of uncoated release backing paper. Sheets were supercalendered using a Beloit Wheeler laboratory supercalender fitted with a temperature controller. The moisture of the sheets was adjusted using 20 and 80% R.H. humidity chambers.
An increase in gloss, densometer and reduction in caliper were evident with the increase of both the steel roll temperature and sheet moisture. Increased sheet moisture seemed to have little effect on the Sheffield Smoothness values. However, the increase in steel roll temperature did product improved smoothness.
