how is viscose made from bamboo?

Dissolving pulp from wood or cotton fibres is treated with sodium hydroxide, then mixed with carbon disulfide to form cellulose xanthate, which is dissolved in more sodium hydroxide. The resulting viscose is extruded into an acid bath, either through a slit to make cellophane, or through a spinneret to make rayon. The acid converts the viscose back into cellulose.
