ABSTRACT:
The throughdryability of dewatered, but wet, sheets made from papermaking fibers can be significantly increased by subjecting an aqueous suspension of the fibers at high consistency to elevated temperatures with sufficient working of the fibers. Such a treatment is particularly effective for improving the efficiency of throughdrying processes used in the manufacture of certain products, such as tissues and paper towels, made from furnishes having a significant amount of secondary or recycled fibers.
