In order to provide the theoretical basis for synthetic fiber dyeing with natural dyes, the dyeing properties of chrysophanol on Poly(trimethylene terephthalate)(PTT) fiber were investigated. The appropriate dyeing condition was 0.5g•dm-3 Paregal O in the dyebath, pH=5 and the final temperature at 100°C~110°C. The dye uptake of chrysophanol on PTT fiber was relatively small, and the building-up property of chrysophanol on PTT fiber was poor. The adsorption of chrysophanol on PTT fiber accorded with Nerst Partition Relation. The partition coefficient decreased with the temperature rising while the dyeing affinity (-△μ0) increased with the temperature rising.
