  1. “Eco-textiles” A new concept is causing the textile industries to rethink their strategies:- Sourcing Manufacturing/producing Marketing

  2. “Eco-textiles” Eco means:- A reduction of every negative impact that textiles have on the environment In the form of Pollution Damage to the planet

  3. “Eco-textiles” Eco means:- A focus on environmental and social compatibility along the entire textile production chain.

  4. Textile process flow Air pollutants Inputs Products Raw materials Production process Dyes & Chemicals Waste water Water Stream Solid wastes Energy Change or modify in all areas.

  5. “Eco-textiles” Eco-friendly textiles and methods Can be used in every stage of production raw material Dyeing and printing use of chemicals energy efficiency waste water management

  6. Eco-friendly textiles and methods Time come to consider Entire life cycle of textile product What happens after a textile has been sold worn washed several times and then thrown away

  7. Discharge from process house color residues electrolytes surfactants toxic air emissions metals RM temperature pH

  8. Discharge from process houseparameter changes BOD COD TSS Metals Aquatic toxicity

  9. Typical fixation % of fibers

  10. Pollution controlColor in waste water affinity of dyes- choice preparation of materials liquor ratio process parameters- time/temp profile. machine energy

  11. Pollution controlColor in waste water maximizing exhaustion/fixation- minimum waste- choice of process. dyes handling- spillage- color dissolution what about residual dyes inside drum.

  12. Pollution controlColor in waste water to dye without or least chemicals- ultimately which retard or reduce the exhaustion. too much chemicals- no of side effects.

  13. Pollution salt 20 – 80 g/l general rule for cellulosic reactive. salt concentration 2000 – 3000 ppm. pollution norms- 250 ppm very difficult to down this.

  14. Pollution controlsalt requirement Hot brand reactive dyeing Cold brand reactive dyeing Direct dyeing Vat dyeing Sulphur dyeing

  15. Pollution controlColor in waste water Direct and reactive dyeing- fixation at end: to fix some dyes.

  16. Pollution controlsalt requirement use lowest possible LR optimize individual shade first time right preparation of RM selection of dyes that needs less salt. Optimize dyeing temperature.

  17. Pollution controlLR ratio and salt
