Abstract:
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 dessolution 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 of 20, 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°C.
Key words: ultrasonic, blended fiber, quantitative analysis, dissolution
