摘要
Abstract
The benzene ester additive synthesized by phthalic anhydride and self-made cationic modification agent WLS was used for polyester fabrics dyeing with disperse dyes in atmospheric pressure. The synthesis process for benzene ester was optimized through single-factor tests. The optimal reaction is under the condition of WLS to phthalic anhydride = 1∶1 (mass ratio), p-toluene sulfonic acid to phthalic anhydride = 0.1∶1.0(molar ratio). water solvent 4 mL/g ( namely, per gram of phthalic anhydride was dissolved in 4 ml water) at 98 ℃ for 2 h. Additionally, the accelerating agent compounded with benzene ester and N-butyl phthalimide (mass ratio 1∶1) was applied in polyester dyeing and the new dyeing process in atmospheric pressure was given. The results showed that the exhaustion rate of dyeing fabrics by the new process basically achieved the effect of traditional dyeing process under high temperature and pressure. However, the apparent color intensity and color fastness of dyed fabrics by the new process were slightly lower than conventional dyeing process. The performances of dyeing fabrics by the new process were much better than dyeing fabrics without auxiliary under atmospheric pressure, indicating that the accelerating effect of the dyeing promoter was very effective. Furthermore, the apparent color intensity and color fastness of dyed fabrics after thermosetting treatment was improved.关键词
