Popis: | The trademarked Papermorphosis technology, consisting of two novel units for separately increasing cross direction (CD) and machine direction (MD) elongation over purely mechanical processes, has been successfully tested on recycling fiber, reaching high elongation values in each direction of over 15% in CD or 20% in MD. Increase of elongation has also had a positive influence on the relative tensile energy absorption (TEA) values in CD and MD. It is well known that mechanical properties in paper basically depend on fiber choice, headbox properties, and refining. With the novel system, elongations in cross direction (CD) and machine direction (MD) can be individually customized, even in paper grades with lower strength deriving from recycled fiber. Customizing elongations also has the effect of improving or better balancing TEA values in both directions. The aim is to improve existing recycling papers and to broaden the use of recycling fiber with respect to the past. |
