超声波处理对棉织物污渍去除的影响

摘要

为研究超声波处理对棉织物的去污效果,分析超声波处理时频率、功率、温度、时间及洗涤剂质量浓度等因素对污渍去除效果的影响.结果表明:在较低频率的一定范围内,超声波对污渍去除有利;超声波功率增加到一定程度后对污渍去除的促进作用没有明显提高;处理温度和洗涤剂用量对预处理效果有明显影响,通常温度越高、洗涤剂质量浓度越大,对污渍去除越有利;延长处理时间明显有利于去除污渍;超声波处理对棉织物的拉伸强度影响不大.%For study of the effect of ultrasonic treatment on the stain removal of the cotton fabric, the treatment factors, such as frequency and power of ultrasound, treatment temperature and time, detergent concentration, were investigated for their effects on the stain removal. The results showed that the frequency of ultrasound is beneficial for the stain removal when it is in low limited range, and the power will show no further improvement when it is higher than certain extent. The high treatment temperature and addition of detergent will benefit the stain removal. Treatment time has significant effect on the stain removal. The treatment of ultrasound has no significant effect on the tensile strength of the fabric.
