The central engineering challenge was not making an existing dyeing process faster but eliminating the fundamental reasons why both conventional and prior-art CO₂ dyeing processes are slow. In conventional water-based dyeing, time is consumed by diffusion-limited exhaustion, repeated baths, fixation, washing, and multiple auxiliary chemical steps.
Surat and Ahmedabad are the two biggest textile hubs. Surat in particular has expanded rapidly—it even started dealing in cotton about two years ago, roughly 5% of its trade now. Surat’s growth has been phenomenal. Ladies’ materials, saris—products from this port city are sold across the world, even to international brands like Zara. Garments are exported too. But Surat faces the same fundamental issue: defaults and fraud. Traders take goods on credit, don’t pay, and simply move on to another city—Bangalore, Mumbai, Ahmedabad. Entire gangs have been operating like this for years.
