Effect of ultrasonic treatment on stain removal of cotton fabric

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.
