Abstract
A spray coating apparatus is provided, wherein a nozzle is arranged to traverse a fabric in one direction whilst simultaneously spraying and oscillating in another direction. The fabric is spray coated with a first pass having a spray zone having uneven distribution in the direction of oscillation, and particularly with a greater density of fluid coverage toward the centre of the spray zone than an edge. The nozzle forming a second and subsequent pass that is off-set from the first and each subsequent pass respectively. The second and each subsequent pass being arranged to overlap with a portion of the previous pass, thereby providing an improved distribution of the spray coating. Moreover, because the spray coating is incremental, the method is easily adaptable to integrate with an ink jet printing process.
