Dry Indigo dyes denim with foam®

There are many facets to sustainability in the textile industry. The denim industry has now come up with an idea that saves water.

Levi Strauss is said to have revolutionised workwear. The father of the Levis brand endorsed the idea of tailor Jacob Davis: splicing the edges of work pants’ pockets and reinforcing the attached fly with the rivets of a horse’s harness. On 20 May 1873 Strauss filed a patent for this idea and blue jeans were born. These reinforced pants sold like hot cakes and rose to worldwide fame. Today, denim pants are as popular as ever as workwear.

The production of the blue fabric for these pants, however, consumes plenty of water. For one pair of jeans weighing 800 grams this adds up to some 8,000 litres. The lion’s share is accounted for the irrigation of the cotton fields, only some 15% for by production proper.

Wrangler is the first denim brand to employ a water-saving foam-based dyeing process to optimise the eco-balance and become more sustainable.

Together with the Walmart Foundation the brand supported the Texas Tech University in the development of a new water-saving manufacturing solution. The denim brand then campaigned for this process with its fabric producers. Tejidos Royo, a Spanish textile producer and denim specialist with sustainable roots, was the first production site to introduce foam-based dyeing under the name “Dry Indigo®” in 2018.

The new certified dyeing technique requires no water. This means there is no waste water either. Furthermore, the energy consumption and waste produced by this dyeing process are reduced by 60% versus conventional dyeing methods, by Wrangler accounts.

At Wrangler the first collection is now available under the brand name Indigood™️ which is marketed as the “most sustainable denim ever”.
