On-line detection device and on-line detection method of dye concentration in printing and dyeing process of connecting vat

Abstract

The invention discloses an on-line detection device of a dye concentration in a printing and dyeing process of a connecting vat. The on-line detection device comprises a dye vat, an outlet valve, a cooler, a spectral analysis system and a return valve which are sequentially connected by pipelines and form a loop, wherein a cleaning pipeline is connected with the pipeline between an outlet of the outlet valve and an inlet of the cooler; an inlet of the cleaning pipeline is connected with a water tank; an angle valve is arranged at an outlet of the water tank; a three-way valve is arranged on the pipeline between an outlet of a constant flow pump and the return valve; and a connector at the bottom of the three-way valve is connected with a waste liquor discharge pipe. The detection device has the benefits that the detection device is applicable to printing and dyeing of the connecting vat, can effectively solve the problems that ingredients of dye liquor in each dye vat are unstable, aberration of the connecting vat is great and the color is unstable, can recycle detection dye, and can reduce the waste of the dye. The invention further discloses an on-line detection method of the dye concentration in the printing and dyeing process of the connecting vat. The method comprises the steps of 1, cleaning, 2, rinsing, and 3, data detection. The method is simple in step and easy to operate.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to an on-line detection device and method for dye concentration in the continuous-cylinder printing and dyeing process. Background technique [0002] At present, due to environmental protection and production cost considerations, continuous printing and dyeing is usually carried out to reuse the dye liquor, that is, to continue printing and dyeing after adding dyes and auxiliaries according to the concentration of the remaining dye liquor. The traditional detection of dye solution concentration and the calculation of the amount of dye or auxiliaries are all done manually, that is, after the concentration of the dye solution is manually detected, the amount of dye and auxiliaries to be added is calculated, but the manual detection of the concentration of the dye solution is cumbersome. , and real-time detection cannot be carried out, and there are large errors in manually dete...

Problems solved by technology

[0004] The present invention aims to solve the problem that the existing dye solution concentration online detection device has complex structure, cumbersome operation, and poor flexibility. Large color difference, unstable color, waste of dyes, and limited detection time resolution. An online detection device for dye concentration in the continuous printing and dyeing process is provided. The device is simple in structure, easy to use, and has high detection accuracy and efficiency. High, good flexibility, can effectively avoid the unstable components of the dyeing solution in each vat, large color difference between vats, and unstable color. At the same time, the detection dye can be recycled to reduce the waste of dye
