Abstract

The textile environmental issues associated with impact represent both cotton agriculture and dyeing processes . Cotton farms emit hazard chemical compounds as Piperonyl butoxide , Cypermethrin, Lambds- cyhalothrin, Chlorpyrifos, Profenofos, Malathion, Lufenuron and Carbendazim. These compounds were detected by multiresidue method analysis for convention 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 monitoring of environmental contaminants and eco-production environmental friendly clothes as model which are more healthy for humans and safe on the ecosystem. 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 parameters like beating point and settings. Rib knitted fabrics were produced with similar loop length and weight using organic and conventional cotton yarn. The fabrics were processed 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.
