Step 1 | CLEANING AND WASHING | CHEMICAL SYNTHESIS by sodium hydroxide (caustic soda) and carbon disulphide. |
PULPING | |
Step 2 | EXTRUSION the colloidal solution generated by chemical synthesis is extruded into filaments that, cut into pieces, create the viscose bamboo fiber. |
BLEACHING | ||
Step 3 | WASHING It is necessary to clean it from chemical residues. |
