Abstract
The invention discloses an alkali deweighting discharging process for high-temperature discharging for gray fabric. The process includes the following steps that firstly, an appropriate amount of water is added to a dye vat, is heated to 50 DEG C, and keeps the temperature for a period of time, and the gray fabric is added; secondly, auxiliaries are then added to the dye vat; thirdly, the temperature of the water solution is increased to 130 DEG C-135 DEG C and kept for 20 min-30 min; fourthly, after temperature keeping is finished, high-temperature waste water in the dye vat is conveyed into a heat exchanger, clear water is injected into the heat exchanger at the same time, the high-temperature waste water is cooled after being subjected to heat exchange, the cooled high-temperature waste water is directly discharged, the clear water is heated after being subjected to heat exchange, the heated clear water is conveyed into the dye vat, and water scrubbing is conducted on the gray fabric through the dye vat; fifthly, the gray fabric is dried after water scrubbing. The high-temperature waste water in the dye vat can be directly discharged through the heat exchanger, the time of a printing and dyeing production process is shortened, cost is lowered, the water scrubbing effect of the gray fabric in the dye vat is also improved, and electric energy and water energy are saved.
