摘　　要：针对间位芳纶纤维筒子纱还原染料浅色染色后存在浮色严重和难清洗的问题,将超声波技术应用于染色间位芳纶纤维的清洗后处理。优化的超声波氧化清洗工艺为:30%过氧化氢溶液3 g/L,超声温度50℃,超声时间20 min。通过考察清洗工艺处理前后纤维的表面形貌、力学性能、热学性能和色牢度,结果发现与常规清洗工艺相比,超声清洗工艺能够有效去除染色纤维的表面浮色,洗后纤维耐皂洗色牢度达4级以上、耐日晒色牢度达到3级;且对染色纤维的力学和热学性能无显著影响。Inview of the serious loose color and difficult rinsing off after vat dyeing of meta-aramid cheese in light color,ultrasonic technology is applied to the post-treatment of dyed meta-aramid cheese.The optimized ultrasonic oxidation clearing process is 30%hydrogen peroxide solution 3 g/L,ultrasonic temperature 50℃,ultrasonic time 20 min.The surface morphology,mechanical properties,thermal properties and color fastness of the fibers before and after different clearing processes are investigated.The results show that compared with the conventional clearing process,the ultrasonic clearing process can effectively remove the loose color of dyed fibers,the color fastness to soaping is above Grade 4,and the color fastness to sunlight reaches Grade 3.It has no significant effect on the mechanical and thermal properties of the dyed fibers.
