Rayon production

Viscose rayon is an artificial textile fibre obtained using chemical and mechanical processes that transform cellulose into filaments.
The raw material for rayon production is normally wood cellulose. The production process consists of transforming cellulose into viscose, which occurs by treating it with chemical compounds. The viscose is then filtered and extruded to produce filaments. The filaments are joined together in threads and washed repeatedly, bleached, dried and packed.

Our conveyor belts are used in the washing process. The quality of the conveyor belt is important for allowing correct washing of the threads and therefore for guaranteeing that a superior quality of rayon is produced.

The conveyor belt surface must be uniform so as to prevent the rayon fibres from remaining attached to the belt. In addition, the belt free passage surface must be consistent and suitable for the treatment. It is important that the chemical compounds used in viscose production are adequately rinsed.

Finally, it is essential that the raw material used in the production of belts is suitable and of a high-quality in order to ensure that the belt does not wear too quickly on contact with the chemical agents to which it is exposed. Normally the materials used to make these conveyor belts are stainless steel 316L (W. Nr.. 1.4404), stainless steel 317L (W. Nr. 1.4438) and stainless steel 317LMN (W. Nr. 1.4439).
