(4) After the nozzle sprays water, the grey fabric is introduced into the dyeing vat.
(5) The door of the machine should be closed tightly, and there should be no air leakage or liquid leakage.
(6) The operating speed of the dyeing machine and the nozzle pressure should be adjusted to ensure that the grey fabric can operate normally.
(7) The dye solution should be added in the prescribed order, and the material should be added slowly and evenly, so as not to affect the dyeing effect.
(8) The dyeing process should be automatically controlled by a computer to ensure accurate dyeing curves.
(9) After the dyeing is finished, wait until the temperature drops below 80°C and the pressure drops to zero before opening the cover, otherwise it cannot be opened to avoid problems.
(10) Dyeing vat is strictly prohibited without water, and the main pump is strictly prohibited from running without water.
(11) When the temperature is above 80℃, it is strictly forbidden to open the reflux valve.
(12) The filter screen must be cleaned every shift to avoid clogging or deposits.
