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] Such as 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 ...

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 combination Dosage (specific gravity of dyestuff 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...

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 combination Dosage (specific gravity of dyestuff 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 dynamic dyeing control method of textiles. The dynamic dyeing control method of the textiles breaks through a concept in a traditional dyeing concept that the effect is better when a pump speed is more rapid; the pump speed of a circulating main pump is pertinently controlled at each process phase or different time periods of each process phase in a dyeing process; the response speed of a dyeing system is adjusted, and the influence degree as great as the influence degree of a chemical preparation is not generated, so that the aim of accurately adjusting is realized. Parameter setting in different phases in a control process of the dyeing process is detailed, and a principle of stable quality, energy saving and consumption reduction is abided; aiming at different order conditions, parameters are formulated pertinently, so that the quality stabilization is facilitated; meanwhile, energy sources are easy to save and the aims of saving energy and reducing consumption are realized.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a method for controlling dynamic dyeing of textiles. Background technique [0002] In the traditional dyeing process, the circulating main pump is kept at a fixed pump speed or runs at the same frequency curve to make the dye liquor reciprocate and penetrate through the yarn and other textiles. The circulating main pump basically works at high speed all the time. Complete the dyeing process in an environment with relatively constant flow. In the process of formulating the actual dyeing process, the characteristics of dyes, chemical agents, and fibers will be considered to formulate different processes. One of the most important points is the need to reasonably control the liquid exchange speed between dyes, chemical agents, and fibers. Different stages , Different process steps and different machine actions often require different liquid exchange rates. In f...
