Abstract

A new water-free dyeing process – Supercritical CO2 art of dyeing was proposed according to the high consumption of water and energy and serious environmental pollution problems. The results indicated that the effects of temperature, pressure and reaction time on dyeing deepness (K/S value) were investigated and the key factor is temperature. The PET fabrics dyed with disperse dyes in Supercritical CO2 were determined and the results showed that the dyeing protects with high dyeing rate and good characteristics, which can meet the requirements of the people on the dyed fabrics pattern and other visual art.
