Recent trends of the pulp and paper industry toward higher pulp yields and less refining have resulted in the opportunity for new approaches to the drying process. Higher yields when combined with less refining mean less flexibility in papermaking fiber. Less flexibility usually results in fewer fiber bonds. Z-direction restraint offers a new approach to efficiently utilize the stiffer fibers and maintain fiber product performance at satisfactory levels. By employing Z-direction restraint it may be possible to make a superior quality linerboard from high-yield furnishes without refining. Linerboard made by this process can have properties far superior to those from conventional papermaking processes.
