Chemicals and dyes innovator Huntsman Textile Effects has developed a new reactive black dye free from restricted arylamines like p-chloroaniline (PCA), which the company claims will help textile mills improve productivity and profitability.
PCA is a hazardous substance commonly found in reactive black dyes.
Huntsman’s new Avitera Black SE dye, an extension of the company’s Avitera SE dye range, meets restrictions on hazardous substances in products and textiles including Oeko-Tex, Bluesign, Zero Discharge of Hazardous Chemicals and the Restricted Substance List.
Avitera Black SE dye helps mills achieve water and energy savings of up to 50 percent and reduce carbon dioxide emissions by 50 percent or more.
Huntsman said the new black dye meets all severe wet-fastness requirements and is well-suited for fabrics that require the highest chlorine-fastness and good light-fastness.
The dye also has low-temperature, high-speed wash off properties, which allow it to dramatically reduce processing time, boosting production by 25 percent or more. It is designed for dyeing at very short liquor ratios with a maximum of four 60-degree Celsius rinses.
“Huntsman Textile Effects continues to invest in the development of innovative new chemistries that meet the needs of the industry and the end-user,” said Jay Naidu, global vice president of strategic marketing and planning for Huntsman. “Our latest breakthrough, Avitera Black SE dye, is redefining economic and environmental sustainability for textile mills. It minimizes processing costs for enhanced profitability, while increasing productivity without additional capital investment. At the same time, it enables mills to differentiate their products in a global marketplace that increasingly demands a clean and transparent supply chain.”
Avitera Black SE dye can be used to produce all deep-black shades, as well as medium-to-deep grey shades.
