AVITERA® SE: A Sustainable Step Change in the Dyeing of Cotton

AVITERA® SE is the first range of reactive dyes to be free from restricted arylamines. Crucially, this covers para-chloroaniline (PCA), a hazardous dyeing by-product that poses risks to people.

Fabrics dyed with AVITERA® SE dyes thus comply with the environmental requirements of leading brands and retailers. This helps mills maintain a positive image and boost the value of their brand while increasing yield, improving productivity and reducing processing costs.

AVITERA® SE: A revolutionary breakthrough

AVITERA® SE innovative dyes is the answer and game changer that meets the environmental standards of the world’s best clothing brands while increasing yield, improving productivity and reducing processing costs.

AVITERA® SE dyes are poly-reactive dyes that ensure rapid and very high exhaustion for cotton and other cellulosic fibers and their blends. More of the dye is absorbed by the fabric, using less salt with less than 7% of the absorbed dye remaining unfixed, compared to between 15% and 30% of conventional reactive dyes. The unfixed dye is also easier to remove at lower washing-off temperatures, as it is not bound to the fabric fibers in a high-salt solution. As a result, processing mills can dramatically increase productivity, since the dyeing and washing-off cycles are substantially shorter, while also making significant savings. Less water and salt are required and energy consumption and CO2 emissions are greatly reduced because water used in the dyeing and washing-off process never exceeds 60°C.
