ENVIRONMENTAL IMPACT OF DYEING AND FINISHING FOR CONVENTIONAL AND ORGANIC EGYPTIAN COTTON

Abstract

The textile environmental issues associated with impact represent both cotton agriculture and dyeing processes. Conventional Cotton farms are cause in the presence of hazard chemical compounds as Piperonyl butoxide, Cypermethrin, Lambds- cyhalothrin, Chlorpyrifos, Profenofos, Malathion, Lufenuron and Carbendazim. These compounds were detected by multiresidue method analysis for conventional cotton in addition to wet processes and dyeing operations ; high BOD,COD,TS, alkaline wastewater and wasted residual unfixed dyes. So this investigation focuses on avoid toxicology parameters by monitoring of environmental contaminants and finding eco-production environmental friendly clothes as model which is healthier for humans and accordance to ecosystem and biochemistry rules . On using organic cotton instead of conventional cotton, where organic agriculture farms there are no synthetic chemical pesticides, no synthetic fertilizers .The ring spun yarns of 30/1 Ne combed organic and conventional cotton were produced with similar preparations same courses and wales of weft knit fabric same stitches formation . Rib knitted fabrics were carried out with similar loop length and weight using organic and conventional cotton yarn. The fabrics were treated in eco textile processing by using Levafix Red CA Gran (vinyl sulphone and difluoropyrimidine) reactive dyes by soft flow machine in single dye bath. The fabrics were tested for colour fastness to washing, water, rubbing, perspiration, light and ecological emission measurements.
