Polyfunctional reactive dyes by Huntsman

A revolutionary new tri-reactive dye range named Avitera SE was showcased at the ITMA 2011. It is Huntsman’s one of the new innovations towards greening the textile processes. It is said to save upto 50% in power and energy.

It is more of a system than a product to ensure the cellulose fiber dyeing more economical with least amount of resource usage. , as well as reduces carbon dioxide(CO2) emissions during the dyeing and washing-off process. It is most productive for dyeing pure cotton as it is a reactive dye-class.

Industrial practice has shown that with AVITERA SE, nearly 90 percent of the dye applied to cotton during dyeing is fixed, as opposed to 60 to 80 percent with conventional reactive dyes. This ensures higher yield.
Fabrics can be dyed and washed off at different temperatures and different quantities of water. Hot dyeing systems require a temperature of 176°F (80°C) to make the bond between dyestuff and fabric permanent. These systems also require boiling water and several rinsing baths to completely remove unfixed dyestuffs.
Conventional warm dyeing systems already offer the benefit of creating the necessary bonds at a lower temperature—140°F (60°C)—but still require a lot of water and high temperature for an appropriate wash-off.
AVITERA SE dyes help significantly reduce water and energy consumption and CO2 emissions since dyeing and the washing-off process never exceeds 60°C.With only five percent or less unfixed dye needing to be removed, instead of the usual 15 to 30 percent, the number of rinsing baths to obtain the required fastness properties is greatly reduced.

 Huntsman Textile Effects works closely with textile mills to adapt their production processes and guarantee excellence in operation, strict cost control and a sustainable system. Helping brands and retailers to coordinate with mills and communicate with consumers improves cooperation throughout the textile value chain, resulting in greater environmental awareness and more sustainable textile processing. 

Avitera SE effects:
 By 2030, the world demand for fresh water will increase by 40 percent. Textile dyeing and finishing processes consume vast amounts of water – in the very parts of the world where it is most scarce. As environmental awareness grows, so does demand for textiles produced in more sustainable ways – yet at low cost.

Up to 26 gallons (100 liters) of water is needed to dye just two pounds (one kilogram) of cotton fabric. With AVITERA™ SE, water usage is reduced to just three to five gallons (15 to 20 liters) per two pounds of material. With the new dyeing technology, one quart (1.3 liters) of fresh water per person per day could potentially be saved in the major Asian textile processing countries such as China, India and Bangladesh. All ready the premier buyers of the world like Lacoste or Marks & Spencer are preferring fabrics from those mills which have adopted the Avitera SE in order to ensure sustainability to their customers. Alps industries, which is the largest home textile exporter from India also has adopted these advanced huntsman dyes and great cost reduction and now they also contributing more towards sustainability as the Managing Director of the company, Ssndeep Agarwal says : “The Avitera SE and Eriopon LT system are revolutionary innovations designed to meet new standards of environmental sustainability and Alps Industries will use this clean technology to take a step in environmental savings.” Bextex from Bangladesh has also signed a deal to use huntsman dyes and chems last year.

Huntsman textile effect made an audit with Masco textiles in Bangladesh which shows the positive effect of their products last year. It proves that their product is certainly helping to reduce resource usage significantly.
