Cellulosic chemical fiber
The starting material for cellulose fibers is cellulose, which is mainly obtained from the cellulose-rich woods of spruce and beech trees or from waste from cotton spinning mills.
With the help of caustic soda and carbon disulphide, the cellulose is liquefied into a spinning mass, then pressed through nozzles and spun into filaments. Due to the natural raw material, cellulose man-made fibers are very similar to cotton in terms of their properties. Modal fibers are modified viscose fibers. They have a higher strength and improved usage properties than viscose fibers.
