Pretreatment

The real problem in pretreatment is the removal of impurities that are not soluble in water. They cannot be removed until they have been solubilized, or at least rendered dispersible, by chemical treatment.

VTexchem programme of auxiliaries for pretreatment is the result of many decades of experience with all the processes involved.
VTexchem has adapted its auxiliaries for pretreatment and bleaching to ensure optimum preparation of the material for dyeing or printing. We assist our customers in achieving the best possible results with our products.
