Cellulose Melt blown from Lyocell Dope by the Nanoval Process

Dr Bernd Riedel of TITK introduced the collaboration between Lenzing, TITK and Nanoval to explore the production of spunlaid lyocell using Nanoval’s Laval nozzle version of melt-blowing. The following are some of the more interesting photos taken during this excellent talk at TITK's Alternative cellulose conference in Rudolstadt (Sept 2006).
