ABSTRACT:
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.
