Abstract: A device for application of a minimum quantity of fluid to a web of goods of a given width, wherein application takes place by means of an application beam in which the fluid is distributed uniformly over the working width through a plurality of fluid lines that branch in the manner of a tree trunk. The outlet openings of the lines terminate in a slot that is open facing the web, the length of the slot being delimited by two lengthwise edges. These edges press against a pressure roller located on the opposite side, i.e the back of the web. By means of these lengthwise edges, as the web passes though, its nap is compressed twice, once at the beginning of application with a first lengthwise edge, after which the nap stands up again in the slot and is saturated with the fluid, and again at the end of the application, after which the web is finally squeezed against the second lengthwise edge.

Abstract: Striped patterning of dyed fabric, particularly dyed denim, is obtained by impacting the fabric with a row of columnar jet streams of fluid generated from a manifold under pressure while conveying it on a support member in a machine direction through a patterning station. The orifice gauge and diameter, manifold pressure, and line speed are selected to obtain optimal striping without blurring, loss of fabric strength or durability, or excessive warp shrinkage. Preferably, the jet strip is removably interchangeable in a common hydrojet manifold for forming different kinds of striped patterns. The back side of denim fabric may be subjected to pre-treatment to cause the surface of the dyed warp side to fill in and darken with color. A strie striping effect can also be obtained using a combination of jet strips. The striped patterning station can be incorporated at any suitable point in a conventional denim finishing range.

Abstract: A method of continuous changing dye-color in spray dyeing for a long tape, which is fed by guides continuously. According to a preferred embodiment, one dye-solution is sprayed for the tape from at least one dyeing-nozzle connected to one feeding line, which is either of a pair of feeding lines and which feeds selectively the one dye-solution or one cleaning-solution.
