Polyester fabric was dyed with indigo dyes at low temperature. The effects of dosage of sodi?um dithionite, sodium hydroxide, benzyl alcohol and indigo dyes, the dyeing temperature and time on K/S val?ue were analyzed. The color fastness of the dyed fabric was also tested. The results showed that the dyeing effect was good when indigo dyes was 2%(omf), the mass concentration of sodium dithionite and sodium hy?droxide were 25 g/L and 4 g/L. The polyesters dyed at 100 ℃ with benzyl alcohol 10 mL/L, 90 ℃ with benzyl alcohol 20 mL/L and 80 ℃ with benzyl alcohol 30 mL/L could obtained the same color depth with the fabric dyed at 120℃. The rubbing fastness and washing fastness were above grade 3 and 4, respectively.
