Why Is Salt Used In Dyeing?
The textile substrate and dye molecule not necessarily should have of homogeneous characteristics to combine with each other. In such case, we require some catalyst to facilitate dyeing action on fabric. Salt plays this crucial role of catalyst. Salt has an extremely high affinity for water.
Broadly speaking, Salt is necessary for three ways, firstly, to drive dye into textile during the dyeing process in textile. Secondly, use of salt leads to maximum exhaustion of dye molecules during dyeing process in textiles. Thirdly it is used as an electrolyte for migration, adsorption, and fixation of the dyestuff to the cellulose material.
Dannenberg industries is developing filters to recovery the salt from textile process water.
we are also able to to filter the colorered process water and re-use the process water , stored processwater will be kept in good conditions and can be used again in the dye process during fixation. the salt conditions can be maintain by measurements.
