#1
DISSOLVING WOOD PULP

The manufacture of viscose begins by dissolving wood pulp in an alkaline solution, generally caustic soda. This forms a viscous solution called "cellulose xanthate".

#2
FIBRES

The cellulose xanthate solution is filtered to remove impurities. It is extruded through spinnerets to create threads. They are then immersed in a sulphuric acid bath to form viscose yarns, which are then plunged into a bath containing coagulating solutions. .

#3
WASHING AND BLEACHING

The fibres are carefully washed to remove chemical residues and achieve a neutral colour. They can then be bleached if necessary.

#4
SPINNING AND WEAVING

Once viscose fibres have been obtained, they can be spun and woven like any other textile fibre. They can be mixed with other fibres to create a variety of fabrics.
