The Cellulosic man-made fibers are produced by dissolving purified cellulose in chemical solvents and regenerating it into fibers. Viscose, one of the most common types, is made by treating cellulose with sodium hydroxide and carbon disulfide, producing a viscous solution that is extruded through spinnerets and solidified in an acid bath.

Lyocell, a more eco-friendly alternative, uses N-methylmorpholine-N-oxide (NMMO) as a solvent in a closed-loop system, minimizing chemical waste and environmental impact. Modal fibers are similar but have enhanced softness and strength.

Advanced production technologies focus on increasing fiber uniformity, improving mechanical properties, regenerated cellulose fiber, viscose rayon, lyocell fabric, semi-synthetic textile, sustainable man-made fiber and reducing the environmental footprint. Innovations in solvent recovery, energy efficiency, and alternative cellulose sources are shaping the future of the industry.
