Embodiment 1

[0014] Embodiment 1: with reference to attached Figure 1-3 . A zero-discharge anhydrous continuous dyeing system, in which multiple sets of spray curtains 1 are arranged vertically at intervals in the anhydrous room 12, and the liquid inlets of the multiple sets of spray curtains are connected to the liquid inlet pipe 5 through a solenoid valve 106, and the signal control terminal of the solenoid valve 106 is Connected to the signal terminal of the PLC controller 11, the inlet of the liquid inlet pipe 5 is connected with the outlet of the pressure pump 7, and the inlet of the pressure pump 7 is connected with the dye tank 8 through a pipeline. The cloth roller 3 and the center shaft 7 at the end of the lower cloth guide roller 3 are driven by the motor 10 to rotate synchronously through the transmission mechanism 9, and whether the pressurizing pump 7 and the motor 10 are working or not is controlled by the PLC controller 11. Each group of spray curtains 1 in the multiple gr...

Embodiment 2

[0015]Embodiment 2: On the basis of Embodiment 1, a printing and dyeing method of a zero-discharge anhydrous continuous dyeing system, when dyeing cloth, the operator inputs the thickness and texture data of the dyed cloth into the PLC controller, and the PLC controller The built-in software automatically controls the opening quantity of the spray pipe 102 in the spray curtain 1, the pressurization pressure of the pressurizing pump 7, the rotation speed of the motor 10, the temperature of the material liquid in the dye tank 8, and commands the position of the dyestuff according to the cloth thickness and texture data input by the operator. The air guide holes on the multiple air guide pipes 14 at the bottom of the tank are pressurized and jetted under the action of the axial flow fan 13, and the material liquid is in a uniform state through the jet, and the dyed cloth is released by the cloth guide roller and enters through the cloth inlet of the anhydrous room 12. A deep and c...

Abstract

The invention relates to a zero-emission waterless continuous dyeing system and method. By adopting the system and method provided by the invention, the dip dyeing step of the cloth is not required, no feed liquor is discharged and continuous dyeing can be realized. In the dyeing system, a plurality of groups of spraying curtains are arranged vertically in a waterless room at intervals, the liquid inlet of the spraying curtains is communicated with a liquid inlet pipe through an electromagnetic valve, the signal control end of the electromagnetic valve is connected with the signal end of a programmable logic controller (PLC), the inlet of the liquid inlet pipe is communicated with the outlet of a booster pump, the inlet of the booster pump is communicated with a dye groove through a pipeline, the upper part and lower part of each spraying curtain are separately provided with an upper cloth roller and a lower cloth roller, a center shaft on the end part of the lower cloth roller is driven by an electric motor through a transmission mechanism to perform synchronous rotation, and the operations of the booster pump and the electric motor are controlled by the PLC. The system and method provided by the invention have the following advantages: 1) feed liquor mist is used for dyeing the cloth for the first time, the dyeing effect is good and no feed liquor is discharged; 2) the recycling and eliminating problems of condensed water in feed liquor mist dyeing can be fundamentally solved, the damage of the condensed water on the piece dyeing effect can be avoided; and 3) continuous dyeing can be realized, the energy consumption is low, the efficiency is high and the environment can not be polluted.

Description

technical field [0001] The invention relates to a zero-discharge and water-free continuous dyeing system and a dyeing method that do not need to be dip-dyeed on cloth, do not discharge material liquid, and have continuous dyeing, and belong to the field of dyeing system manufacturing. Background technique [0002] CN 1958941A, title "a kind of fluid anhydrous dyeing technology", the supercritical CO2 fluid dyeing process uses fluid CO2 in a supercritical state as a dye carrier to dye fabrics, first inject liquid CO2 into the dyeing system, and the amount of carbon dioxide is based on CO2 storage The volume is calculated at 1.5 kg per liter, and then the temperature in the dyeing system is increased to 80-140°C, and the pressure is increased to 20-30MPA, so that the liquid CO2 reaches a supercritical fluid state, and then the circulating pump is started to dissolve the dye and dye the fabric in a cycle , the dyeing time is 20 to 40 minutes. After dyeing, the fabric is rinsed ...
