Bio2Future course "Man-made cellulose fibers"
After a short introduction about the history and the market situation of MMCFs, the focus is placed on the chemistry and technology of the dissolving pulp (raw material) and staple fiber production based on the two major commercial process, the Viscose and the Lyocell processes. In addition, students will get an overview on alternative MMCF processes.
The course provides the fundamentals of cellulose dissolution, characterization of rheological and viscoelastic behavior, the dynamics of polymer chains in solution, structure formation during the regeneration of cellulose fibers. Students can expect to gain a better understanding of cellulose structure and morphology, with a special emphasis on the structure-property-relationship.
The conversion of staple fibers to products that go into making apparel and other textile goods is subject of the final part of the course. Students will learn yarn production, knitting and knitwear, weaving, dyeing and printing technologies, fabric quality and sustainability and gain an outlook on new fabric developments including smart textiles. The dyeing and finishing fundamentals encompass the basic concepts of textile wet processing with emphasis on the tuning of the surface properties with respect to hydrophilicity and hydrophobicity.
