Modal and lyocell fibers represent, respectively, the second and third generation of cellulosic manmade fiber technology. The dyeing of lyocell fibers requires significantly fewer steps than do dyeing processes for previous generations of cellulosic fibers. Its 99 percent recovery rate greatly increases the environmental friendliness of cellulosic fiber processing. Properties that play the most important role in the processing of cellulosic fibers include wet tenacity, wet elongation modulus, dyeability, water retention capacity, fiber swelling, and fibrillation. Dyers should select a reactive dye that achieves good dye distribution in the substrate during the first phase of exhaustion. Finishing machines used with modal fibers should minimize tension at the fiber surface. Lyocell fibers feature tenacity and dimensional stability that allow the use of all processing methods.
