Abstract
Abstract Striped colorations are produced on dyeable substrates incontinuo us or sheet form by applying a plurality of dyestuff streams to the substrate at selected points across its width while the substrate is moved longitudinally relatively to the points of application, and then passing the substrate between nip rollers, the rate of application of the dyestuff streams being so controlled that on passage through the nip the dyestuffs are squeezed into the substrate to form non-overlapping longitudinal stripes of the desired widths.
