摘要

Three thiadiazolyl azo dyes were used as disperse dyes for polyester fibres. The dyeing medium was supercritical CO_2. The experiment conditions were 80 to 120°C and 2500 to 4000 psi pressures. The dyeing results were compared with traditional dyeing in water. The results shown that the disperse dyes have high substantivity towards polyester fibres and very good fastness.
