The nozzle blows the fabric open while simultaneously spraying atomized dye solution onto the fabric. However, sometimes the fabric entering the vat is not fully fluffed and opened, resulting in uneven dyeing. Furthermore, dust on the fabric surface is not absorbed and directly enters the vat, affecting the dyeing effect. Utility Model Content
