A process for producing space-dyed acrylic yarns is disclosed, wherein an acrylic yarn containing at least 50% by weight of basic-dyeable acrylic fibers has up to 80% the length thereof contacted with a resisting amount of an aqueous solution of a preferably divalent metal cation at a pH of about 2.5 to about 8.0. The yarn is then bulked by steaming to fix the ion on the fibers, and thereafter the yarn is dyed, with at least one basic dye, and the treated areas of the yarn resist the basic dye to produce a space-dyed appearance. The products of the present process may be used in knit and woven goods and the like whenever a space-dyed appearance is desired.

Process for the production of space-dyed effects on acrylic yarns

A process is provided for batch treatment of textile material such as yarn packages, raw stock, knit goods, muffs or the like by placing the material in an enclosed zone, evacuating the enclosed zone to provide a vacuum therein, and then flooding the evacuated zone with a treating agent by placing the evacuated zone into communication with a second zone having the treating agent therein under a positive pressure. A substantial pressure differential exists between the two zones, and the treating agent flows extremely rapidly through the textile material whereby, at the very outset of the treating process, the treating agent is uniformly distributed over the surfaces of the textile material and substantially in its original concentration and condition. The treating agent includes a dyestuff and other agents, such as scouring agents, whereby several treating operations can be performed simultaneously.
