Globally, the textile industry is witnessing a paradigm shift in the Concepts, Applications and Technology of wet processing. The influencing factors for this shift are considered to be cost pressures, high quality demands, environment regulations, fashion trends & supply chain logistics.

The above factors have forced the Dyers to formulate strategies to cope up with the following major challenges:

Increase productivity: Focus on RFT (Right-First-Time), RET (Right-Every-Time), shorter process cycles.

Cost optimisation: Use of high tinctorial dyes, multifunctional auxiliaries, reduction in utility cost.

Shortened processing: Robust recipes, quick lab-dips.

Flexibility in operation: ability to process short run.

Eco- concerns: AOX, COD, TDS, Fluorine content, etc

Stringent demands: higher fastness ratings, shade consistency.

The global scenario of class of dyes applied on cellulose (Figure 1), clearly shows the enormous importance of Reactive dyes. The segment wise application of Reactive dyes (Figure 2) reveals that the demand for warm dyeing is on the rise.

The globalisation of the textile supply chain has increased competition, thereby forcing the Indian dyers to look beyond the recipe costs and increase overall production efficiencies and also to reduce the hidden costs like power cost, water cost, steam cost and effluent treatment cost. This translates to the dyestuff manufacturers as the need to develop high strength dyes with better wash-off profile and higher wet fastness properties


Keeping the above factors in view, Atul has developed TULAREVS XL range, a state-of-the-art Reactive system, manufactured using innovative membrane technology, to meet stringent fastness requirements (like that of M&S fastness) and deliver high reproducibility from laboratory to bulk (RFT) and also from Bulk to Bulk (RET)
