  • Patent number: 4152113
    Abstract: A system for continuously reusing and recycling water and chemicals in consecutive dyeing cycles wherein hosiery goods are placed in a vat and subjected to dyeing, rinsing and finishing operations. The unabsorbed dye bath, rinse waste water and finish waste water are continuously recirculated to eliminate waste discharge to municipal sewage facilities. The waste waters are clarified in a treatment zone, and the unspent dye bath is continuously recirculated or periodically clarified as necessary or desirable. Treatment of the waste waters and the unabsorbed dye bath removes dyes while permitting certain chemical constituents to remain in the clarified water for reuse in subsequent dyeing cycles.
