Ã¼ËprÅ. n 1: A a regenerated cellulose fiber derived from cotton (linter the, ultrafine silky fibers that stick to the seeds of the cotton plant afterâit s been) ginned that has been dissolved in a solution of ammonia and copper. oxideo me, cupro/rayon/viscose processing cancels out the benefits of using cotton waste. says: April 7, 2012 at 7:06 am.

Rayon is a versatile fiber and is widely claimed to have the same comfort properties as natural fibers, although the drape and slipperiness of rayon textiles are often more like nylon. It can imitate the feel and texture of silk, wool, cotton and linen.The fibers are easily dyed in a wide range of colors.uprammonium rayon has properties similar to viscose but during production, the cellulose is combined with copper and ammonia (Schweizer's reagent). Due to the environmental effects of this production method, cuprammonium rayon is no longer produced in the United States.
