Compared to the conventional viscose rayon process, Lyocell process using NMMO as a solvent provides a naturally-friendly, less toxic, relatively simple method for producing regenerated cellulose fiber with excellent properties. Existing wood pulp based Lyocell, however, shows some disadvantages such as a forest destruction and easy fibrillation caused by its high orientation in the wet state. So in this study we prepared a novel Lyocell fiber using a different cellulosic source, cotton linter pulp, with a lab-scale spinning equipment, investigated the effect of spinning conditions such as the dope concentration, spin draw ratio, and air gap distance, etc. on physical properties and fibrillation of the fibers, and compared the fibers with wood pulp-based Lyocell in terms of physico-chemical aspects.
