The airflow dyeing machine adopts the principle of aerodynamics and uses circulating air instead of water to draw the dyed fabric for cyclic movement. Therefore, compared with the traditional overflow dyeing machine, the dyeing bath ratio is greatly reduced. There are two ways of communication between fabric and dye liquor in the air dyeing machine: one is air atomization, and the other is air pressure infiltration.
Air atomization is to first atomize the dye liquor through a special nozzle and disperse it in the air flow, and then the air flow with the atomized dye liquor communicates with the dyed fabric and pulls the fabric to circulate. In the process of communication, the atomized dye solution not only has a large contact area on the fabric, but also has a strong penetrating force to the fabric fibers, which accelerates the dispersion speed of the dye solution into the fiber. The nozzle of Germany's THEN (THEN) airflow dyeing machine is selected in this way. The air pressure infiltration method is to use two nozzles, that is, a pure airflow nozzle and a liquid flow nozzle. The liquid flow nozzle is in front, and the dyed fabric first passes through the nozzle to communicate with the dye liquor, and then enters the airflow nozzle through the cloth lifting roller. The dispersion rate of liquid to fabric fibers. The nozzle of the Thies airflow dyeing machine in Germany is selected in this way. Judging from the current application situation, most of the air-flow dyeing machines are in the form of air-flow atomization, and they have a good application effect. This article also reviews the airflow dyeing machine with this nozzle method.
