Title: Dyeing of polyester with HA type alkali-resistant disperse dyes
Abstract: Three alkali-resistant disperse dyes of Orange HA, Red HA-3B and Blue HA are applied to polyester dyeing. The influences of the dosages of sodium hydrate and dispersant, dyeing temperature and time on dyeing behaviors are analyzed, and the building-up property and color fastness of the dyeings are discussed. The results show that three alkali-resistant disperse dyes feature good alkali resistance,and are suitable for alkali dyeing of polyester fabric. The optimum dyeing process is dyes 2%(omf), sodium hydrate 2 g/L,dispersant NNO 2 g/L, and dyeing at 130 ℃ for 60 min. The polyester dyeings have a higher K/S value and good color fastness to washing and rubbing, and three dyes have good building-up property within the dye dosage of 2%(omf).
