Avient & Coloro Partner On Sustainable Fibre Dope-Dyeing

Avient Corporation and Coloro have partnered to supply the global textile industry with top-quality specialised colourants for the dope-dyeing of synthetic fibres and help brands achieve sustainability goals.

“Avient products have also recently received the Global Recycle Standard (GRS) and Bluesign System Partner certifications,” the company said in a press release.

Avient is a supplier of specialised and sustainable material solutions and services, while Coloro has a universal colour system that decodes colour as the human eye sees it.

Coloro recently launched its unique colour feasibility intelligence for the textile industry to illustrate achievable colours, it included Avient’s range of standard colourants to match its colours into the dope-dyeing process.

“Dope-dyeing, or spin-dyeing, is considered a more sustainable colouring process for fibres because it uses no water and requires less energy than the widely used bath-dyeing process,” Avient stated

The colourant is in the form of concentrate pellets added to the polymer pellets during the extrusion and melting process.

The plastic mass is then shaped into filaments, spun, and texturised into an already-dyed yarn and no water is involved, thereby reducing the number of steps and, as a result, the amount of energy needed to add colour.

“Major textile brands are under pressure to show how they will implement sustainability strategies to reduce CO2 emissions, water use, and wastewater,” said Bob Lee, GM, Color & Additives at Avient China.

“This is where dope-dyeing and Avient’s colourant technology, along with Coloro’s colours, can help,” Lee added.

“There was previously limited information on the achievability of selected colours in the final garment, especially when making colour decisions based on sustainability and circularity,” Detlev Pross, Chief Strategy Officer of Coloro, Shanghai said.

“As we now have over 300 well-known brands and retailers using our colours, we see it as our responsibility to help them address and minimise emissions and pollution,” Pross too added.

“It was a natural and obvious choice to collaborate with Avient, a global leader in sustainable colour solutions. We are excited that they supported this project to help provide Coloro colors for dope-dyeing,” he stated

Avient and Coloro are currently offering 226 Coloro colours as standard colourants for dope-dyeing, with plans to expand in the future.
