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).
