The reactive dye produce a lot of effluent problems in terms of % AOX, BOD, COD, TDS etc. in spite of its
capability of produce wide range of colours and varieties of gamut in hue. In addition the use of salt as electrolytes provides higher chances of eco-hazardous impact problems and end-users comfort related properties. The % dye fixation is being always a problem to reactive dyeing on cotton due to the higher degree of dye hydrolyzation inside the dye bath. In this current work we had tried to develop an unconventional reactive process in both like salt free acidic medium reactive dyeing and salt free alkaline dyeing on pure cotton fabric. Results of the current study shows that alkaline medium salt free reactive dyeing on cotton shows higher colour strength (K/S value), good mechanical properties-bending length modulus, flexural modulus, less generation of the % AOX etc. It also can be concluded that acidic medium salt free reactive dyeing is also better in terms of quality than the conventional reactive dyeing
method in the industries.
