Problems solved by technology

In fact, in many process control stages, it is necessary to slow down the liquid exchange rate. Excessive liquid exchange rate often easily leads to unstable product quality, resulting in quality problems such as dyeing, color difference, low strength, and excessive hairiness, and the circulation of the main pump is always maintained. High-speed operation also consumes a lot of energy, which is not conducive to energy saving and environmental protection; on the contrary, there are only a few non-critical washing steps that require rapid liquid exchange, so it is necessary to increase the pump speed to speed up the liquid exchange speed and compress the production cycle to complete faster. Production Order
The traditional dyeing method controls the liquid exchange rate by adjusting and controlling the type and amount of chemical additives and the running time of the main circulating pump, which makes it difficult to ensure stable dyeing quality

Embodiment 1

[0031] like figure 2 As shown, in the dyeing process stage, in the initial stage (0-5min), the fibers need to be fully wetted to ensure sufficient exchange between the dye solution and the fibers, so the highest pump speed is set to 100%, and the lowest pump speed is set to 70% cycled. In the second stage (5-10 minutes), after the fiber is fully wetted, the dyeing preparation is added, because the addition of the dyeing preparation has a greater impact on the dyeing system environment (such as pH changes, etc.), in order to delay the severe environmental degradation of the dyeing system Changes may cause quality risks, so the highest pump speed is set at 60%, and the lowest pump speed is set at 0% for circulation. In the third stage (10-15 minutes), after the dyeing preparation is added, the environment of the dyeing system is basically stable, and the dyeing preparation and dyes in the dyeing liquor begin to exchange, react, and combine with the fibers. At this stage, a cer...

Embodiment 2

[0033] Select the same yarn count and the same batch of pure cotton yarn, and arrange the dyeing of the following formula in Table 1.

[0034] Table 1

[0035] Dye combinations Dosage (specific gravity of dye to textile) reactive yellow dye 0.006％ reactive red dye 0.1％ reactive blue dye 0.25％

[0036] Proceed as follows:

[0037] (1) input pretreatment, dyeing, posttreatment program by the dyeing process of embodiment 1 in the machine platform;

[0038] (2) Hang the cotton yarn into the cylinder, lock the cylinder head and complete the pretreatment, dyeing and posttreatment processes according to the program requirements;

[0039] (3) Open 5 layers of cotton yarn for visual inspection and computer testing (take the first layer, that is, the outermost layer of cotton yarn as the standard, and test the dyeing quality of the second to fifth layers of cotton yarn).

[0040] (4) During the entire dyeing process, the dynamic dyeing process of Exa...

Embodiment 3

[0042] The dyeing process parameters and steps are the same as in Example 2, and the dyeing formula is changed in the following table 2.

[0043] Table 2

[0044] Dye combinations Dosage (specific gravity of dye to textile) Reactive Turquoise Dye 0.05％ reactive yellow dye 0.004％ reactive blue dye 0.15％

[0045] See Table 3 for the comparison of the dyeing quality of pure cotton yarns obtained by dyeing in Examples 2 and 3. The dynamic experiment 1 among the embodiment 2 is identical with the method and train of thought of the dynamic experiment 2, and the pump speed parameter (such as pump speed or time) in the single specific implementation process is slightly different and changes, and the dynamic experiment 3 and the dynamic experiment in the embodiment 3 4 for the same reason.

Abstract

The invention relates to a textile dynamic dyeing control system. The textile dynamic dyeing control system comprises an input module, a digital-analog conversion module, a pump speed control module and a communication module. The textile dynamic dyeing control system breaks through a traditional concept that a higher pump speed is better in a traditional dyeing concept; and by virtue of targeted control of the pump speed of a main circulating pump of every process stage or in different time periods of each process stage during dyeing, the response speed of a dyeing system is adjusted, a considerable influence degree, for example a chemical agent, will not be generated, and an aim of precise adjustment is achieved. By detailing parameter settings of different stages during dyeing process control, abiding by a principle of stabilizing quality, saving energy and reducing consumption, and performing targeted parameter making by aiming at different order form conditions, the textile dynamic dyeing control system is beneficial for stabilizing quality, and is also beneficial for saving energy at the same time, thereby achieving the aims of saving energy and reducing consumption.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dynamic dyeing control system for textiles. Background technique [0002] In the traditional dyeing process, the circulating main pump is constantly running at a fixed pump speed or with the same frequency curve to make the dye liquor reciprocate and circulate through textiles such as yarn. The circulating main pump basically works at high speed all the time. The dyeing process is completed in an environment with a relatively constant flow rate. In the process of formulating the actual dyeing process, the characteristics of dyes, chemicals and fibers will be considered to formulate different processes. One of the most important points is that the liquid exchange speed between dyes, chemicals and fibers needs to be reasonably controlled. Different stages , different process steps and different machine actions often require different liquid exchange rates. I...
