Abstract

The optimum carrier concentrations were obtained by the maxmium exhaustion ratios of polyester fabrics at 80℃. The optimum concentrations of methylsalicylate, acetophenone, anisole, propiophenone, 2-ethyl hexyl alcohol, ethylene glycol and propylene glycol were 3g/ℓ, 12g/ℓ, 7g/ℓ, 5g/ℓ, 3g/ℓ, 35g/ℓ, and 40g/ℓ, respectively. Azo, anthraquinone, and quinoline disperse dyes were quite stable up to pH 10.3, but nitro disperse dye were severely hydrolyzed in alkaline dyeing. The tensile strength decreased with increasing dyebath pH because the polyester fabrics were easily decomposed by alkali. The reduction cleaning could be canceled in alkaline dyeing because the carriers were solved by alkali during dyeing.
