The airflow dyeing machine mainly adopts the principle of aerodynamics, which circulates the air instead of water, and draws the fabric in a cyclic motion. Therefore, if it is compared with the traditional overflow dyeing machine, the dyeing liquor ratio However, in the airflow dyeing machine, the exchange of fabric and dye liquor can be mainly divided into two types, the atomization of airflow and the penetration of air pressure.
First of all, the atomization of the airflow is mainly to pass the dye liquor through a relatively special nozzle, and after atomization, it is dispersed in the entire airflow. The fabric is drawn and circulated. During the whole exchange process, the atomized dye solution not only has a large contact area for the fabric, but also has a very strong penetration force to the fibers in the fabric, which effectively accelerates the dye solution in the fiber. The rate of internal diffusion throughout.
Secondly, the infiltration of air pressure is completely different from that of air flow. Two nozzles are also used, one of which is pure air flow, and the other is liquid flow. Before dyeing the fabric, both need to pass through the liquid flow. The nozzle can then be exchanged with the dye liquor, and then it will enter the nozzle of the airflow from the cloth lifting roller, because the airflow will penetrate the fabric with pressure on the dye liquor. At the same time, the diffusion speed of the entire dye solution will be appropriately accelerated. Judging from the current usage situation on the market, the atomized dyeing form of airflow is widely used, and the effect of the whole use is very good.
