Supercritical carbon dioxide (SC-CO2) dyeing is an ecological waterless dyeing method without any dyeing auxiliaries and waste water discharge. In this paper, we introduce continuous dyeing processes of zipper tape in SC-CO2 while recycling the gas simultaneously. Compared to water dyeing, this new processes could reduce CO2 gas consumption and increase production efficiency, and lead to 20% cost decrease. The dyed products also present excellent color fastness to fading, staining, drying, and wetting, which are all rated at a grade of 4-5. The dyed zipper tapes show excellent shade consistency by different dyeing autoclaves, proving that this continuous processes is suitable for the rapid and diverse color change of smaller lots.
