This is another development of the very popular jet dyeing machines. The main difference between the Air Flow Machine and Jet Dyeing machine is that the airflow machine utilizes an air jet instead of the water jet for keeping the fabric in circulation. Typically the fabric is allowed to pass into the storage area that has a very small amount of free liquor. This results in a reduction in consumption of water, energy and chemicals.
The figure below shows how in an Airflow Machine the bath level is
always under the level of the processed textile. Here the fabric does
not remain in touch with the liquor (the bath used is below the basket
that holds the fabric in circulation). This invariably means that the
bath conditions can be altered without having any impact on the process
phase of the substrate.
