AII funded this project because textile dyeing is one of the most resource-intensive and polluting steps in the supply chain, consuming vast amounts of water and energy. While waterless dyeing (dope dyeing) already exists, adoption has been limited due to high minimum order quantities and limited flexibility. This project aims to solve these barriers to adoption.
This project develops and scales a waterless textile coloration technology that combines dope-dyed yarns with optical color-mixing and machine learning. Instead of dyeing fabrics in water baths, color is added during yarn extrusion and then combined during weaving to create thousands of colors. The system uses 6–10 primary-colored yarns to generate over 8,000 colors, supported by a machine learning model that predicts color recipes and ensures accuracy. The pilot is taking place in three facilities.

The innovation lies in overcoming the key barrier to waterless dyeing adoption, minimum order quantities, by enabling color flexibility through optical mixing and machine learning. Importantly, it does not require entirely new infrastructure, as it can operate on existing spinning and weaving equipment, which significantly lowers adoption barriers.
If successfully commercialized, the solution could be applied across a wide range of synthetic and potentially natural fibers, enabling industry-wide transformation. However, scaling will depend on brand adoption, validation of product quality, and successful integration into existing manufacturing processes.
