Background

Gas flow dyeing is comparable to conventional liquid flow dyeing machines in that the fabric is circulated by means of a gas channel containing moisture or water vapour, and almost all fibre materials and mixtures thereof can be bleached and dyed without the need for a dye liquor or an aqueous medium to transport the fabric. The most important characteristic is that the consumption of dye, chemical auxiliary agent and energy is greatly reduced.

Unlike traditional overflow jet dyeing, air dyeing relies primarily on pulling the fabric in a circular motion. The dye liquor is sprayed out through a special nozzle, and then enters a pipeline through which the dyed objects pass along with the flowing of the air flow, so that the dye liquor is contacted with the dyed objects repeatedly, and the dyeing process is finished. However, in order to uniformly dye the dyeing liquid on the object to be dyed, the dyeing liquid needs to be sprayed out by a special nozzle to form a fine mist, but the nozzle is expensive and is not easy to clean.
