Abstract

160 GSM Single Jersey cotton knitted fabric was dyed with conventional Remazol reactive dye and the latest Avitera reactive dye (Huntsman). A detailed comparison of the process parameters and fastness properties of these dyed fabrics was studied. The investigation exposed that Avitera delivered better dyeing performance including fastness to washing, perspiration, and rubbing than conventionally dyed fabrics. Concerning process parameters, Avitera dye required less soda, and salt and no addition of other auxiliaries. Also, this new Avitera reactive dye is more eco-friendly, cost-effective and energy-saving than conventional Remazol reactive dye. CMC DE and Da* colour deviation were significantly higher between the dyed samples. Again K/S value of the Avitera dyed sample was superior to that of Remazol dyed samples because of enhanced dye uptake. Sequentially reflectance and relative indicators of the latest reactive dyed samples also experimented
