Changes

The viscose manufacturing process is chemically intensive and requires copious amounts of water. Wastewater effluents from processing must be properly treated to avoid contamination of surrounding water bodies. Air emissions caused by the viscose process include sulfur, nitrous oxides, carbon disulfide and hydrogen disulfide. Chronic exposure to carbon disulfide can cause damage to the nervous system in humans.[6]

===Dyeing and finishing===

The dyeing processes for viscose made from bamboo is a multi-step process that involves ample amounts of water at high temperatures (50°-95°C), salt, acetic acid and caustic soda. Mild peroxide bleach may also be necessary to remove residues of sulphur.
