Embodiment 1

[0033] A kind of dyeing process monitoring method of the present embodiment comprises the following steps:

[0034] (1) The dyeing formula used is Dye1:2.0%Salt:50g / LSoda:15g / L, liquor ratio 1:10, and the process curve is as follows figure 1 shown;

[0035] (2) if figure 2 As shown, the dye vat with temperature sensor, the dye solution cooling pool, the spectrophotometer (dual-wavelength UV-visible spectrophotometer) with quartz glass flow cell, pH meter, conductivity tester (liquid medium conductivity test) are connected through the pipeline. Apparatus) and liquid suction pump are connected in turn to form a loop. A water circulation pipeline is arranged outside the dye liquor cooling pool, and flowing cold water is passed through the pipeline to rapidly cool the dye liquor. At the same time, a data acquisition device is set, and the data The acquisition device includes a computer (PC)-dyeing vat and a PC-data monitoring device, the temperature sensor is wirelessly connect...

Embodiment 2

[0043] A kind of dyeing process monitoring method of this embodiment, the dyeing formula that adopts is Dye2:1.0%Dye3:1.0%Salt:50g / LSoda:15g / L, liquor ratio 1:10, process curve is as follows image 3 As shown, its steps are the same as in Example 1, and the difference is: in the uninterrupted circulation flow described in step (3), the flow velocity of the control dye liquor is 0.7m / s, and the temperature of the dye liquor after being cooled by the dye liquor cooling pool is is 28°C.

[0044] After repeated monitoring three times, the average value of each data was taken, and the results are shown in Table 2. The average deviation of the three results was 0.01, and the test was highly repeatable and the results were accurate.

[0047]

Embodiment 3

[0049] This embodiment is a kind of dyeing process monitoring method. The dyeing formula and steps adopted are the same as those in Embodiment 1, the difference is that in the uninterrupted circulation flow described in step (3), the flow velocity of the dyeing solution is controlled to be 0.8m / s, and the The temperature of the dye liquor after cooling in the dye liquor cooling pool is 30°C.

[0050] After repeated monitoring three times, the average value of each data was taken, and the results are shown in Table 3. The average deviation of the three results was 0.01, and the test was highly repeatable and the results were accurate.

Abstract

The invention relates to a dyeing process monitoring method. The method includes the following steps of firstly, sequentially connecting a dyeing vat, a dyeing liquid cooling pool, a data monitoring device and a liquid suction pump through pipelines to form a loop, and making a computer terminal in communication with the dyeing vat and the data monitoring device, wherein the data monitoring device comprises one or more of a spectrophotometer with a flowing pool, a pH meter and a conductivity tester; secondly, starting the liquid suction pump when dyeing starts, making dyeing liquid continuously circulate and flow between the dyeing vat, the dyeing liquid cooling pool and the data monitoring device; thirdly, collecting data of the dyeing vat and data obtained through monitoring of the data monitoring device in the dyeing process at the set time moment, and recording the collecting time. By means of the method, the whole dyeing process can be reflected through real-time, accurate and objective parameters, the basis is provided for accurately judging the dye combination of dyeing and reasonability of the process, the dyeing process is improved more scientifically, and the dyeing quality is improved.

Description

technical field [0001] The invention relates to the field of automatic control in the printing and dyeing industry, in particular to a dyeing process monitoring method. Background technique [0002] Since dyeing fiber is a chemical reaction process, and it needs to be carried out in a pressure and high temperature container, the whole process cannot be monitored in the actual dyeing production, and it is often reversed by the dyeing result after the dyeing process. Accuracy and controllability are not guaranteed. How to reflect the relationship between the dyeing process and its corresponding influencing parameters in real time and replace traditional empirical judgment with scientific data is an urgent problem to be solved. [0003] At present, some of the existing online testing methods are mostly in the stage of laboratory exploration, unable to monitor the dyeing process accurately and completely in actual production, and only aim at a single parameter in the dyeing pro...
