  1. Water Use in Textiles Phil Patterson Managing Director, Colour Connections Consultancy ltd

  2. The Rime of the Modern Clothier Water, water, everywhere, And all the brains did shrink, Water, water, everywhere, Nor any drop to drink

  3. Industrial Use • ~100 – 150 l/kg • Scouring • Dyeing • Washing • Heating! • Cooling! • (don’t forget fibre)

  4. Domestic Laundry • ~10 – 15 l/kg/wash • Washing • Rinsing

  5. .......not just water • Energy to heat it • Chemicals in it • Pollution

  6. Industry • Use high temperatures • Inefficient • Indirect heating • Boiler makes steam • Steam shipped to machines • Heat exchanger • What’s insulation? • Water used for cooling • Often no effluent treatment

  7. Domestic • Uses lower temperatures • Low chemical usage • Direct heating • Water heated in machine • Or from insulated hot water source • Always to an ETP

  8. Durability means Sustainability • 150 l/kg per kg to produce • (20,150 l/kg for cotton) • 15 l/kg per kg to wash • Items washed 10 times or less have bigger production impact!

  9. Durability means Sustainability • Factor in cotton growing

  10. Is water used or ‘borrowed’? • Some always used • (evaporation) • It’s never put back in form it was taken • Water-recycling massively under-utilised

  11. Fashion Crime

  12. Number 1 Fashion Crime • Pollution • Most pollution is where water is plentiful • India • Bangladesh • China

  13. Actions • Shift focus to textile production • Priority • Traceability • Compliance with environmental laws • Reduction in needless textile consumption • Reduction in water consumption

  14. Traceability – The foundation of everything • How to achieve it • Legislation? • Shame, Pressure? • Brand co-operation? • Fashion media • Everyone fears traceability • “commercial sensitivities” • Fear of what will be found

  15. Compliance • Who? • Retailers? • Makes them higher cost • Governments? • Short term damage to economy

  16. Textile Consumption • Lower volumes • Higher value • Prices to reflect true cost • Taxes based on volumes bought/sold?

  17. Reducing Water Consumption • Evolution or revolution? • Right first time • Best available technology • Re-cycling • Liquid carbon dioxide • Marginalisation of cotton (Kyoto style targets) • Product labelling based on facts not hype

  18. Summary • Water ‘use’ is not always an issue • Pollution is the major issue • Energy use associated with water use is a major issue • Focus on industry not domestic • Best practice could halve water consumption in dyeing
