The Indian Textile Industry, forefounder of nations industrialization, employment generator & revenue earner is experiencing a major upheaval in todays stiff global competition.
The textile processor is caught up in a web of fierce competition from other Asian countries, stringent environmental/ pollution regulations, scarcity of trained man power, escalating energy costs & dwindling export earnings. This has brought in awareness in terms of need for technology upgradation, machinery modernisation, innovative application techniques, cost optimized processing & increasing production capacities for achieving economies of scale. One of the ways to minimize the impact of water, energy, effluent treatment costs, enhancing per person productivity is by resorting to continuous dyeing methods in place of short batch wise processing.
Vat dyes are best suited for such continuous dyeing application by Pad Dry Chemical Pad Steam process, where the thrust is on uniform, level dyeing in long yardages, meeting stringent fastness requirement, lab to bulk reproducibility, minimal tailing (shade grouping) and low effluent discharge. However, there are various factors which determine trouble free application of Vat dyes on continuous dyeing range
Atul is the only Indian dyestuff manufacturer who has successfully stood up for more than 50 years & survived all these upheavals based on its strong R & D, capacity to adopt to market trends & innovative product developments. Atul has developed a new range of micro-disperse Vat dyes- Novatic MD, a full range covering entire shade gamut exclusively suited for dyeing of Cotton & blends in woven fabric form on continuous dyeing range.
A Schematic diagram of continuous dyeing range is given below.
The salient features of Novatic MD dyes are
