dc.description.abstractReactive dyesexceptionally dominant for cellulosic materials as they are ecologically protected and having greatfastnessproperties.but the application of these dyeing involves the high concentration of salt which negatively affects natural environment as it creates saltiness in drain water stream.The present work focus on theelimination of salt used for the dyeing of cotton goods with reactive dyes. This study introduces salt free reactive dyeing on cotton which would not contribute to ecological contamination. The basic purpose of this study is to explore promising approach to reduce cost of dye process. In this project, the fibre modification technique based on chitosan and 1,2 dichloroethane has been discussed. When the fabric is treated with polyacrylamide which make the cellulose to act like as wool fibre and thereforecotton can be dyed with reactive dyes at neutral PH in the absence of electrolyte and alkali. Similarly when fabric is treated with an emulsion of 1,2 dichloroethane and after that treatment the fabric is subjected to amination wit sodium hydroxide.The treatment was found to develop the color fixation also. The modification was studied through fundamental examination.en_US
