Archroma is making its Avitera SE technology accessible to more brands and mills with the launch of Avitera SE Generation Next for the more cost-effective sustainable dyeing of cellulosic fibres and blends.

With an improved cost-to-performance ratio for new dark and extra-dark shades, the extended Avitera SE Generation Next range helps mills produce differentiated articles that comply with the environmental requirements of leading brands and retailers while increasing yield, improving productivity and reducing processing costs.

“Avitera SE has coloured the world’s best clothing brands for more than a decade,” said Dhirendra Gautam, vice president of product marketing and strategy at Archroma Textile Effects. “This next-level solution delivers the same environmental benefits while helping fashion and textile companies sustain their financial viability.”

Dyeing darker shades has traditionally been more challenging and costly, calling for higher dye concentration, increased water and energy use and additional steps or re-dyeing to achieve a uniform color. Darker shades also tend to fade more quickly than light-coloured fabrics, especially when exposed to sunlight and repeated home laundering.

“We have a taken a huge leap forward to make it possible to produce consistent and long-lasting dark and extra-dark shades in a more sustainable way at a total cost that is more comparable to traditional cellulosic dyeing technology,” Dhirendra said.

With high-speed low-temperature wash-off, high process reliability and excellent reproducibility, Avitera SE Generation Next allows mills to achieve water and energy savings of up to 50% and to also slash CO2 emissions and effluent discharge by up to 50%. The dyes are free from arylamines, including PCA and are said to offer excellent fastness properties, retaining their vibrant colours through repeated home laundering and exposure to light, perspiration and chlorine.

Three new and improved dark colours have been added to the Avitera SE range:

- Black Pearl SE, a greenish-cast black dye with high colour consistency that can be used to correct metamerism.

- Blue Horizon SE, a deep blue element with good light fastness in medium to deep shades, as well as high oxidative fastness and high resistance to nitrogen oxides (NOx) in the atmosphere.

- Night Storm SE, a new navy shade with a greenish cast and strong build up, recommended for dyeing the deepest navy and combination shades.
