the bottom line.”
The constant improvement of the manufacturing
process over the years has paved the way for DyStar’s
current success. The numbers speak for themselves
with double-digit growth rates in the major denim
manufacturing areas, e.g., 40 per cent growth in South
Asia.
“In anticipation of greater demand
for DyStar Indigo Vat 40% Solu-
tion and an increased market
share, the DyStar Group is
planning to expand capacity
at its Nanjing indigo plant in
China,” said Harry Dobrow-
olski, CEO of the DyStar
Group. The expansion reaf-
firms DyStar’s commitment
to the denim industry.
As global awareness of
environmental issues created by
the textile supply chain increases,
brands, retailers and their industry
partners are looking for more sustainable solu-
tions for their businesses. With the recently announced
project to develop electrochemical dyeing of indigo in
collaboration with RedElec, DyStar is maintaining its
position as the leading sustainable solution provider.

DyStar and its owner, the Zhejiang Longsheng
Group, celebrate 115 years of technical indigo syn-
thesis at Ludwigshafen, Germany, where the first
commercially feasible manufacturing process was
launched.
The history of synthetic indigo goes all the way
back to 1897, with the introduction of, “pure
indigo” from BASF. Demand for syn-
thetic indigo dyes was so huge that
by 1913, natural indigo had been
almost entirely replaced. To
date, more than 260,000 tons
of the dye has been produced
at the Ludwigshafen plant.
This is sufficient to dye about
26 billion pairs of jeans which,
if lined up end-to-end, would
cover the distance from the
earth to the moon 87 times.
With its patented DyStar Indigo
Vat 40% Solution, DyStar has con-
tributed to the continuing success story of
synthetic indigo. “Pre-Reduced indigo is a very
consistent and clean type dye”, notes Dean Barley,
Denim Dye Department Manager from Mount Vernon
Mills. “Having a consistently clean indigo helps us
produce more first quality denim day in and day out.
More first quality goods also generate more money to
