DyStar, a colouration specialist for the textile and leather industries, and its owner, the Zhejiang Longsheng Group of China, principally engaged in the manufacture and distribution of specialty chemical products, are celebrating 115 years of technical Indigo synthesis at Ludwigshafen, Germany, where the first commercially feasible manufacturing process was launched.
The journey of synthetic indigo, which began way back in 1897 with the introduction of “pure indigo” from BASF, gave rise to such a huge demand that by the year 1913, natural indigo had been almost entirely replaced. To date, more than 2,60,000 tonnes of the dye has been produced at the Ludwigshafen production plant, sufficient to dye about 26 billion pairs of jeans.
“With our patented DyStar Indigo® Vat 40 per cent solution and contribution to synthetic Indigo, we are planning to expand the capacity at our Nanjing Indigo plant in China,” informed Harry Dobrowolski, CEO, DyStar Group, reaffirming their commitment to the denim industry.
