Abstract
A hybrid fluid jet apparatus is disclosed which is particularly useful in uniformly applying liquid dye to a fabric substrate. The applicator is controlled in an electrostatic control mode while operating below the practical limit of speed for electrostatic operation to achieve uniform fabric coverage. When fluid is being supplied to the substrate at its maximum flow rate in the electrostatic control mode, the applicator senses that the 'full flow' condition has been reached. The applicator is then controlled to operate in a non-electrostatic control mode to control the fluid flow rate by modulating the fluid pressure received at the orifice array in accordance with the required fluid flow rate needed to achieve a uniform application of fluid to the substrate.
