Abstract
A method of metering the rate of flow of a dye solution from a spray nozzle for dyeing an elongate fabric material comprises spraying a test liquid equivalent to the dye solution over a plate member impervious to liquid, accumulating the test liquid and measuring the rate of its flow per unit length of time, thereby evaluating the performance of the spray nozzle. The rate of flow of such test liquid is simulated for actual dyeing operation to pre-adjust the jet pressure of the spray nozzle and/or the spaced of feed of the fabric material so as to attain uniform intensity of color on the dyed material.
Claims5
A method of metering the rate of flow of a dye solution from a spray nozzle for dyeing an elongate fabric material, which method comprises positioning said spray nozzle rotatably between a vertically supported plate member and a vertical run of said fabric material, spraying a test liquid equivalent to said dye solution over said plate member substantially equal in width to said fabric material to be dyed, allowing said test liquid to flow by gravity down said plate member, and measuring the rate of flow of said liquid per unit length of time as it is accumulated in a reservoir.
