The use of supercritical CO2 allows for a solvent-like behavior under specific temperature and pressure conditions, enabling it to penetrate fabrics effectively, thereby facilitating the dyeing process.

The process begins with the preparation of the fabric, which is usually pre-treated to enhance the dye’s affinity for the fibers. Once treated, the fabric is placed in a dyeing chamber. Here, supercritical CO2 is introduced, reaching pressures typically around 1,000 psi and temperatures of about 35°C to 70°C. Under these conditions, CO2 takes on properties of both gas and liquid, allowing it to dissolve dyes efficiently while maintaining a low environmental footprint.

During the dyeing phase, the supercritical CO2 behaves as a medium that carries the dye molecules to the fabric. This interaction occurs without the extensive use of water or harmful chemicals, significantly reducing the environmental impact typically associated with conventional dyeing methods. Furthermore, the precise control over temperature and pressure enables textile manufacturers to optimize color application while minimizing waste.

After the dyeing process is complete, the pressure is released, causing the CO2 to return to a gaseous state, leaving the dye adhered to the fabric. This phase also allows for the easy recovery of the CO2, paving the way for its reuse in subsequent dyeing cycles. Overall, waterless dyeing technology not only conserves water but also offers a sustainable alternative for producing vibrantly colored textiles, ultimately transforming the textile industry.
