Innovation, customer demands and expectations for better quality and cost efficiency have become the major challenge for tissue and towel manufacturers. Tissue and towel manufacturers have long turned to new technology and better processes to be able to produce products that are softer, stronger, and more absorbent. In these days, tissue and towel markets worldwide represent potential for continued growth, both for consumer and commercial products. Developing the right products to take advantage of this growth potential has become crucial for both equipment manufacturers and chemical companies.
For more than 20 years, tissue makers were adding dry strength additives to the pulp in order to improve MD and CD tensile without increasing the refining energy. The advantage of such chemical additive was to meet tensile targets without adding refining energy to the pulp. Meeting the tensile without increasing refining energy is critical for premium grades because increasing refining energy is affecting Bulk/Basis weight and softness in a very negative way.
This paper will discuss the technology and a case study from a very recent success at a Cascades Tissue site. This new enzyme technology has shown very promising results on Eucalyptus and Recycle fibers. The enzyme has been able to outperform their previous dry strength/Coagulant package at very low dosage.
