摘　　要：为提高纤维检测行业进行混纺纤维定量化学分析的检测效率,缩短检测时间,将超声波技术应用于棉/涤混纺纤维定量化学分析的溶解过程中,探讨了超声波频率、溶解时间、溶解温度等对超声辅助溶解过程的影响,为超声波辅助溶解在混纺纤维定量分析中的应用提供支持。实验结果表明:在棉/涤混纺纤维定量化学分析中采用超声波辅助溶解可有效加快溶解速率,大幅缩短溶解时间,从而提高检测效率,很好地替代传统溶解方法;在20、28、40kHz超声频率辅助溶解下的实验结果均可满足实验精度要求;在超声频率为20kHz,溶解温度为50℃时,溶解30min后可达到最佳溶解效果。In order to improve the detection efficiency and shorten the detection time of blended fibers quantitative chemical analysis in the fiber inspection industry,ultrasonic technology was applied in dissolution of cotton polyester blended fiber quantitative chemical analysis. The factors affected the ultrasonic assisted dissolution process were discussed,which are ultrasonic frequency,time and solution temperature. The purpose is to provide support for ultrasonic assisted dissolution in the application of quantitative analysis field. The experimental results show that ultrasonic assisted dissolution employed in cotton polyester blended fiber quantitative chemical analysis can effectively shorten the dissolution time and improve the detection efficiency; it can be a good alternative to conventional dissolution methods;and it can meet the testing accuracy with ultrasonic assisted dissolution under the ultrasonic frequencies of20,28 kHz and 40 kHz. The best dissolution effect can be achieved in 30 min under the conditions of the ultrasonic frequency of 20 kHz and the dissolution temperature of solution temperature is 50 ℃.
