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.
One of the biggest challenges is competing with the speed and pricing of mass production. Handwoven fabrics require time, patience, and craftsmanship—qualities that often clash with the fast-paced rhythm of today’s fashion market. Another major challenge is the shortage of modern equipment that could enhance the quality and consistency of the weavers’ work. Many artisans rely on outdated tools, which limits their potential to meet larger-scale or high-end production demands.
