Beschreibung
Zusammenfassung:	A method for space dyeing yarn wherein a rapidly advancing yarn is intermittently deflected into and out of a nip of a pair of rotating dye applicator rollers, such that those portions of the yarn which pass through the nip are subjected to a rapidly applied and substantial compressive force in the nature of a hammer-like impact in the nip, to cause the dye carried by the rollers to deeply penetrate into the yarn. In the illustrated embodiment, the yarn is advanced past a plurality of such pairs of dye applicator rollers, and an external pattern control acts to deflect the yarn into and out of the various nips in accordance with a predetermined program.
