Abstract
Supercritical CO2 dyeing technology is a high-tech green dyeing method that differs from traditional dyeing techniques.It uses supercritical CO2 fluid instead of water as the dyeing medium,effectively addressing the water pollution issues associated with conventional dyeing and printing industries.Moreover,plant-based dyes are derived from nature,are sustainably renewable,have good environmental and ecological compatibility,and are harmless to human health.The supercritical CO2 dyeing technology of madder dye was investigated,with the effects of temperature,pressure,and time on the dyeing results being analyzed.Cotton fabric was modified using cationic reagents and hydrophobic agents to examine the influence of such modifications on the dyeing effectiveness of natural dyes in supercritical CO2 fluid.Through analysis of the K/S value,Lab value,and DE of the dyed cotton fabric,the impacts of pre-treatment and co-solvents on the dyeing effect were evaluated.The results indicate that hydrophobic treatment of cotton fabric and the addition of co-solvents can enhance the supercritical CO2 dyeing of natural madder to some extent,although the addition of co-solvents reduces the levelness of the dyeing.关键词
