Huntsman Textile Effects said it has developed a groundbreaking new reactive black dye Avitera Black SE to address potential impurity of hazardous substance p-chloroaniline (PCA) within reactive black dyes.

According to Huntsman, independent analytical test institutes have confirmed that this innovative dyestuff is free from restricted arylamines, including PCA.

“This will help meet increasingly stringent environmental standards to help textile mills improve their productivity and profitability for better economic sustainability,” it informed in a press release.

An extension to the award-winning Avitera SE dye range, the new Avitera Black SE dye meets tighter and stringent restrictions on hazardous substances in supplied products and treated textile articles.

These include Oeko-Tex, bluesign, Zero Discharge of Hazardous Chemicals and the Restricted Substance List (RSL) standards of the world’s premier brands.

“Since its launch, the Avitera SE dye range has been continuously extended to deliver improved environmental and economic benefits,” Huntsman observed.

“With the release of the Avitera Black SE dye, the Avitera SE range of dyes free from restricted arylamines, including PCA, is now complete across the entire shade gamut and color spectrum,” it explained.

Avitera Black SE dye enables mills to achieve significant water and energy savings of up to 50 per cent and reduce CO2 emissions by 50 per cent or more.

“Avitera Black SE dye sets a new benchmark for fastness performance and is excellent for fabrics that require the highest chlorine-fastness and good light-fastness,” the dyes producer noted.

With its low-temperature, high-speed wash off properties, Avitera Black SE dye also reduces processing time to boost production by 25 per cent or more compared to commodity black.

It is designed for dyeing at very short liquor ratios, typically 6:1 or less with a maximum of four 60 centigrade rinses to ensure the lowest processing costs.

Avitera Black SE dye can be used to produce all deep-black shades and is suitable for medium-to-deep grey shades as well.

“Huntsman Textile Effects continues to invest in the development of innovative new chemistries that meet the needs of the industry and the end-user,” Jay Naidu, global vice president said.

“Our latest breakthrough, Avitera Black SE dye, is redefining economic and environmental sustainability for textile mills,” he too added.

“It enables mills to differentiate their products in a global marketplace that increasingly demands a clean and transparent supply chain,” Naidu also observed.

Huntsman also added that the Avitera SE dye range has been globally recognised for its contribution to supporting environmental and economic sustainability for the textile industry.

The dye range was the overall winner in the 2014 ICIS Innovation Awards as well as the first recipient of the ICIS Innovation with Best Benefit to Environment or Sustainability Award. (AR)
