These features enable unique comfort, cooler feel, brighter colours and brilliant shades of the final processed fabric. Modal is a 2nd generation Cellulose fiber with a high wet modulus, unique soft feel and good dimensional stability. Excel is the 3rd generation viscose fiber having high dry and wet strength, good dimensional stability and clean manufacturing technology. Viscose, Modal and Excel are regenerated cellulose fibers resembling unique properties like softness, brightness, luster, smoothness, drape, etc. compared to Cotton fabrics.
