Abstract

Dyeing of cotton fabric is for apparel textiles and home textiles worldwide are more commercial because of its contented properties. Dyeing of cotton fabric with hot band reactive dye involves huge amount of sodium chloride as an exhausting agent to absorb the dye molecules in to the core of cellulose molecules of cotton fibre. The exhausting agent sodium chloride used in reactive dyeing is not fully absorbed by cotton fibres and remains in dye bath after completion dyeing and it is drained to effluent treatment plant. The amount of sodium chloride in dye effluent increases the load of effluent treatment and creates more pollution into water and land. Hence to reduce the load of effluent treatment and the problem to the environment use of huge amount of sodium chloride is replaced with poly vinyl amine chloride. The effect of use Poly vinyl amine chloride in reactive dyeing as exhausting agent was studied by testing wash fastness, rubbing fastness, light fastness, tensile strength, and environment testes BOD, COD, TDS value and TSS value. It was found that the dye uptake was excellent and the fastness properties were also an excellent. The impact of dye effluent to environment also found marginally less as compared to sodium hydroxide load to environment. It was determined that the use of Poly vinyl amine chloride in reactive dyeing was more effective.
