【摘要】 研究超声波辅助过醋酸漂白纯棉针织物的方法。试验结果表明 ,在超声波条件下 ,过醋酸用量6g/L ,焦磷酸钠 3g/L ,pH值 7,温度 5 0℃ ,漂白 60min ,织物白度与常规过醋酸漂白工艺相比提高了 3～ 4,且超声波对过醋酸稳定性的影响很小更多还原

【Abstract】 In this paper, bleaching of cotton knitting fabric with peracetic acid under ultrasonic was discussed. The results indicated that under ultrasonic, the concentration of peracetic acid 7g/L, pH value 7, temperature 50℃ and time 60 minutes, the whiteness of the fabric can improve 3～4 compared with normal peracetic acid bleaching method. In addition, it is founded that there is little effect to the stability of peracetic acid under ultrasonic.更多还原
