Textiles maker Tejidos Royo has developed a way to dye yarns black, using almost no water.

The Spanish company in February 2019 launched Dry Indigo, an innovative blue denim fabric that uses foam to disperse dye on the yarns, and which took 10 years to develop.

As well as reducing water, chemicals and energy, the process results in no wastewater, and has been included in ranges from brands including Wrangler and Lee.

Since then it has worked on a way to create black yarns. “We are now able to control the fixation and concentration,” said Jose Royo, sales director.

The new product is called Dry Black. It reduces water usage by 99.1%: it cannot claim 100% due to the water that is used to rinse the dye through the machine at the end. It also reduces chemicals by 75% and energy by 65%.

Tejidos Royo is based in Valencia and produces sportswear and denim fabrics.
