This presentation explores the potential of alternative feedstocks and fibers in the production of hygiene tissue paper and selected man-made cellulosic fibers, focusing on real-world applications and the associated challenges.
In the context of hygiene tissue production, it is important to challenge the common perception that nonwood fibers are primarily suited to replace short fibers (hardwood). In fact, nonwood fibers are more effective in complementing or replacing long fibers (softwood) due to their ability to enhance tensile strength. This property enables reductions in basis weight and presents opportunities for cost savings in fiber procurement.
The choice of pulping process—whether chemical, semi-chemical, or mechanical—has a significant influence on the final properties of the furnish. However, when considering both tissue paper performance and capital investment, mechanical pulping proves to be the most advantageous. Although managing fines generation remains a critical challenge, ongoing research offers promising strategies to mitigate these issues.
The presentation will also compare the advantages of various feedstocks, highlighting their potential to improve cost-efficiency and sustainability in the production of tissue paper and man-made cellulosic fibers. Specific applications and innovative solutions will be discussed in detail, offering a comprehensive view of this evolving and transformative field.
