METSO NTT, A NEW TEXTURED TISSUE PAPER CONCEPT

Based on the results of an extensive R&D project, Metso Paper is launching an innovative process, named Advantage NTT, for making a new category of tissue, the textured tissue. The new NTT concept combines high energy efficiency and significantly improved bulk compared to conventional dry crepe, with unique product qualities.

The patented new Advantage NTT process will give tissue makers new tools and powers to develop unique grades to meet the increasing market demands for higher quality bath and facial tissue, handkerchiefs and kitchen towels. The process opens up a new category, textured tissue, which produces a product with high silky softness and bulk. Fibre savings, based on less fibre per roll, are possible due to the 50- 80 % increase in bulk produced in NTT textured tissue as compared to the conventional process. At the same time, the energy input per roll produced can be decreased by 20 %, depending on the product made, helping to reduce the carbon footprint of NTT tissue products.

NTT gives extreme flexibility with respect to product characteristics and energy savings, allowing tissue makers to choose the best solution for their specific market situation. Adding to the flexibility, the configuration can swing to conventional tissue production, at even higher energy savings.

NTT is based on proven machine technology that has been reconfigured and literally turned on its head to come up with the new qualities and process advantages.

The NTT textured product, and the patented NTT technology behind it, will officially be launched and demonstrated on the Metso Paper pilot machine at the Tissue Making 2008 conference held on18-19 September in Karlstad, Sweden.
