Ultrasonic improves the color fastness of polyester cotton fabrics
During the dyeing process of dark polyester cotton fabric,there was a problem of dye satura-tion,which led to poor color fastness of the fabric.Under the action of ultrasonic wave,the optimization pro-cess of fabric soap washing was investigated:frequency 35 kHz,power 0.6 W/cm2,water temperature 60℃,and vehicle speed 28 m/min.The results showed that the color fastness of ultrasonic soap washing process was improved compared with traditional soap washing process,especially the color fastness to wet friction was increased by 0.5 level,and the water saving and energy saving were obtained.
