Viscose is produced using a wet spinning process. The product is based on pulp, which is obtained from wood. The action of caustic soda lye and carbon disulphide produces a viscous, spinnable mass. The spinning mass is then pressed through nozzles. To remove the solvents, the spinning cable is led through a bath. After several de-aeration and separation processes, this strand is then dried, stretched and crimped. This improves strength and facilitates subsequent processing of the individual fibres. Finally, the strand is cut into short fibres.
The properties of viscose:
Polyethylene terephthalate (PET) belongs to the polyester family. Terephthalic acid and ethylene glycol react to PET by polycondensation.
PET is produced by a melt spinning process: The molten polymer is pressed through spinnerets and an antistatic agent is introduced to prevent the individual strands from becoming electrostatically charged. In order to facilitate subsequent fibre processing, the final step after stretching is crimping and cutting.
