I am astounded at the considerable use of seemingly environmentally unfriendly chemicals in the production of denim.
Organic cotton and herbal indigo dyeing is prohibited by cost,but I think premium denim jean manufactures should make a more conserted effort to promote their use.

Your articles in dyeing and washings are very much useful.I would
like know more about zero percent discharge from dyeing process.
In Tirupur,India,struggle to over come the problem with any
right solution. Your valuable advice and guidance can make
market size in Tirupur say around 18000 crore rupees will be
gradually diluted into other areas in India and later vanishing
from the textile map.
Please forward your expertise advice to our Tirupur Exporters
Association.
Warm regards,
Sathyanarayanan iyer pv,Tirupur
