Xanthation Aids

The need for xanthation aids (dissolving or viscose grade pulp)

Uniform spray application of xanthation aids on dissolving pulp sheet improves efficiency of the xanthation process in the viscose manufacturing plant.

The use of xanthation aids provides the following benefits:

  • Improved filterability of viscose. 
  • Improved spinnability of the fibre.
  • Reduced jet clogging. 
  • Reduced breaks during the viscose reaction thus leading to prolonged life of the spinnerets. 
  • Reduced consumption of expensive and toxic carbon disulphide in the viscose plant.

Application areas

Xanthation aids should be diluted with warm water and sprayed over the pulp sheet in pulp mills before packing. For finer control, this can also be mixed with the pulp sheet in the pulper in the viscose manufacturing plant.

Dosage levels range from 0.8 to 1.5kg/Adt depending on the specific needs of the viscose plant (production rate, blending ratio of different pulp and other operating conditions).


Amazon Papyrus has a range of xanthation aids for different raw material furnishes and for specific objectives of the viscose manufacturing plant.

Xanthation aids are complex polyoxyethylene derivative of an aromatic compound.

These products are readily soluble in viscose and spin baths and being surface inactive, does not cause foaming problems in the de-aeration process or loosen old deposits in the pipe lines and tanks. They are stable in viscose and spin baths and are compatible with anionic, cationic or non- ionic viscose.
