dispersion for Textile dyestuff

Ultrasonic cavitation refers to the dynamic process of growth and collapse of micro-gas core cavitation bubbles in the liquid that vibrate under the action of sound waves, and when the sound pressure reaches a certain value.

When ultrasonic waves act on liquids, a large number of small bubbles can be generated. One reason is that partial tensile stress occurs in the liquid to form a negative pressure. The decrease in pressure makes the gas originally dissolved in the liquid supersaturate and escape from the liquid and become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.

Introduction：
Ultrasonic dyeing has been widely used in printing and dyeing industry.There are studies on ultrasonics for polyester knitted fabrics
Dyeing, and contrast with the conventional dyeing without ultrasonic treatment. Use infrared and microscope to study the effect of ultrasonic atomization treatment on the dispersion dye liquor. The data shows that after ultrasonic treatment of the disperse dye, the particles of the dye are significantly smaller and the molecular structure distribution is more uniform, and the
chemical structure is not significantly changed.

Advantage：
Fast coloring; improve color strength and color fastness; low-temperature printing and dyeing does not damage the fabric; compatible with a
variety of fabrics.
