ABSTRACT:
Apparatus for wet processing fabric with fluid, which includes a primary container for containing and processing fabric, mechanism for partially flooding the primary container, and a counterflow recycling mechanism. The primary container includes a kier for wet processing fabric, a chamber disposed within the kier, for receiving fabric and fluid therein, the chamber having a plurality of perforation, wherein the mechanism for partially flooding the primary container includes a receptacle, disposed within the kier beneath the chamber, being positioned to collect fluid which passes through the perforations of the chamber. The receptacle is sized to surround the chamber so that the amount of fluid in the chamber is sufficient to permit the flow of fabric through the chamber and the amount of fluid in the kier outside the receptacle is sufficient to meet net pressure suction heat requirements of the pumping system employed by the apparatus. The counterflow recycling mechanism includes a plurality of ancillary containers for containing fluid and a mechanism for transferring fluid back and forth between the primary container and the ancillary containers. A method for wet processing fabric with fluid is also disclosed.
