Matte is relative to flat light, that is, non-glossy surface. It can avoid light pollution and is convenient to maintain. The matt surface is a bit hairy, like the surface of a frosted glass.

Ultrasonic cleaning is the direct and indirect effect of the cavitation, acceleration and direct flow of the ultrasonic waves on the liquid and the dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose. In the ultrasonic cleaning machines currently used, cavitation and direct flow are applied more. The existing ultrasonic cleaning is applied to the surface coating processing industry, machinery industry, electronics industry, medical industry, semiconductor industry, watch and jewelry industry, optics. Industry, textile printing and dyeing industry. However, the application in the textile printing and dyeing industry is limited to the cleaning of finished textiles, and the advantages of ultrasonic cleaning compared to conventional washing cannot be fully utilized.

The existing cotton fabric textile processing process adopts high temperature desizing scouring, oxygen bleaching, alkali mercerizing treatment and dyeing after caustic soda. During the mercerizing process, the cotton fiber swells violently, the cross section of the fiber tends to be irregular, and the fabric's hair effect, whiteness, gloss and dyeing properties are greatly improved. After the process, the cotton fabric has good gloss and dyeing performance, but the fabric feels poor, and it needs to be improved by soft finishing.
