| Abstract: | The migration behavior of reactive disperse dyes containing β-hydroxy-ethyl sulfonyl sulfuric ester group at different stages of dyeing and the ther-mofixation on the polyester-cotton blend were thoroughly investigated. The sublimation properties of the dyes were examined and the diffusive process of dyes in the vapor phase during thermofixation was identified. It was concluded that thermofixation conditions would effect the dye distribution in the cotton and polyester portions in the blend. The relationship between the dye molecule structures with respect to their distribution in the cotton and polyester portions was established. A dyeing mechanism of reactive disperse dyes for polyester-cotton blend was outlined and discussed. |
