Dry Indigo Dye brings new light to sustainability

A Spanish company is known for its research institute, AITEX has certified Tejidos Royo’s Dry Black process as an Eco and Sustainable technology. The textile makers working alongside a machinery company, Gaston and a consultancy Indigo Mill designer who has been coined by Text Tech University have developed a method to dye yarns in black color without using water.

In February 2019 the Spanish company launched Dry Indigo which is an innovative blue denim fabric that utilizes foam to dispense dye on the yarns. This has taken over 10 years of intensive research and development to bring to market.

This process reduces water consumption, chemicals and energy as well as the water waste. This new technology has been included in various brands collection such as Wrangler and Lee.

Jose Royo the director of sales stated that they are now able to control the fixation and concentration of the black yarns.

Dry Black claims to reduce water usage by 99.1%. The company cannot claim it to be 100% as water is required to rinse the dye through the machine at the end. It also claims to reduce chemicals and energy by 75% and 65% respectively.

Tejidos Royo is located in Valencia and produces sportswear and denim fabrics. AITEX is a private research agency that conducts trials and provides certification for textiles and articles over a range of sectors which include workwear, sports, leisure and aerospace.
