Dissolving pulp as a raw material The most important type of fibre used for production of the viscose fibres is wet spinning technology, which allows the production of staple fibres or filaments. Their starting material is dissolving cellulose, which is prepared from spruce, birch, beech and eucalyptus. Sulphite cook is used for production, and nowadays,
