During the production of facial tissue, operators can adjust the tissue's transparency using the following methods:
Reduce the moisture content of the paper web entering the sizing press to enhance absorption.
Increase the moisture content of the paper rolls to facilitate calendering.
Increase the temperature, pressure, and number of nips within the calender section.
Adjust the raw material composition-specifically, by favoring sulfite pulp over sulfate pulp-as the former is more amenable to refining.
Increase the total amount of pulp refining performed on the tissue machine, with particular emphasis on fine refining to enhance fiber fibrillation and bonding strength.
Improve sheet uniformity; excellent uniformity is crucial for achieving high transparency.
