超声波洗毛工艺

Ultrasonic wool scouring process

将超声波技术应用于水介质洗毛工艺中,通过选用不同细度的原毛,采用不同的洗毛温度、洗毛时间和洗涤剂用量,探讨这些参数对原毛洗净效果的影响,并与传统洗毛方法的效果进行了对比研究。结果表明:采用超声波洗毛,洗净毛质量可以达到与常规洗毛工艺相同的水平;但采用超声波洗毛可以明显缩短洗毛时间,提高洗毛效率。同时,通过SEM观察洗净毛,发现超声波洗毛对羊毛的鳞片有刻蚀作用,鳞片受到一定程度的损伤。

This paper studied the ultrasonic technology applied in wool scouring with water. The effects of scouring temperature, time and dosage of detergent on the quality of the scoured wools of different diameter were investigated. The results were compared with that of the traditional wool scouring and it was found that the ultrasonic wool scouring can achieve the same quality level as the traditional, but it needs less time and has higher efficiency. However, it is observed by scanning electron microscope （SEM） that the ultrasonic process results in etching effect on wool scales, thus damaging them to certain extent.
