explain in detail, the preparation of rayon fibre.
Answers
Explanation:
Rayon fiber is produced from the ripened solutions by treatment with a mineral acid, such as sulfuric acid. In this step, the xanthate groups are hydrolyzed to regenerate cellulose and carbon disulfide. Aside from regenerated cellulose, acidification gives hydrogen sulfide (H2S), sulfur, and carbon disulfide.

A manufactured cellulosic fiber, rayon is neither a synthetic nor truly a natural fiber. It can mimic the characteristics of silk, linen, and cotton but rayon has poor elastic regain and was best dry cleaned
