1. November 2011

2. Impact of lots of people
7 Billion people in 2011 / 9 billion people by 2050
Our dependency on many current production methods comes at a huge and unsustainable
economic, environmental, and social cost.
Feeding, clothing, and providing shelter for everyone does not come free. Everything has a cost.

house/retailer
Claim lower water use Single bath system Decrease water consumption
Potential for lower carbon footprint Low processing temperature Decrease energy consumption &
CO2 emissions
1.Create flexible fading effects on Color modification of indigo & Differentiated and varied casts
one substrate sulphur dyestuff compared to the chemical
2. Reduce the number of substrates treatment
required to get varied wash effects
Controlled shade adjustment Lower material rejection compared
Improve quality and consistency with chemical bleach
Controllable and reproducible Reduce the variation batch on
process batch
Increase care for people Neutral pH and biodegradable Gentle & safe processing
conditions
No damage to LYCRA® elastane No strength loss Reduce the risk of fabric damage
fiber containing denim when
compared to chemical bleaching
