Description

Dyeing machine control system with dyeing residual liquid as the control element

The invention relates to a dyeing machine control system, in particular to a dyeing machine control system that takes dyeing residual liquid as a control element.

The current general dyeing process has the following common problems:

1. Please refer to Figure 7. In the traditional dyeing process, after adding various fiber materials, yarns and cloths, adding water, adding chemicals, and closing the door, it is impossible to know how fast the dye is colored during the dyeing process.

2. In the past, it was traditional to do stage dyeing and residual liquid absorption application experiments in the laboratory. The experiment process is as follows:

(1). Staged dyeing is used to study the coloring rate change of the prescription during the heating process, for a single dye, the coloring temperature of the dye can be analyzed, and for the prescription, the pros and cons of the combination can be analyzed.

(2). The period of stage dyeing out of the vat is generally: heat preservation at room temperature 30°C for 2', and heat preservation at 40°C, 50°C, 60°C, 70°C, 80°C, 90°C, 98°C and 98°C for 30'. (The heating rate is 1℃/min), and then the temperature is lowered from 98℃ to 80℃.

(3). The residual liquid from each section of the cylinder cannot be dumped, and each bottle should continue to be absorbed for residual liquid for analysis of residual liquid

Traditional dyeing technicians will set up a dyeing process similar to dyeing nylon fiber cloth based on the color results and experience, hoping to achieve the goal of not dyeing flowers, but also dyeing and matching colors.

Therefore, the above-mentioned stage dyeing and residual liquid absorption application experiment caused cumbersome dyeing work, and the dyeing temperature has been preset, and it cannot be changed with the actual dyeing rate during dyeing.

3. The traditional dyeing polyester fiber can also be set to different times in a similar way. The color change of sampling under the temperature is used as a record reference, which is used as a reference for designing the speed of dyeing and raising the temperature.

Traditional dyeing technicians will set up a dyeing process similar to dyeing polyester fiber cloth based on the above sampled color change results and experience, hoping to achieve the goal of not dyeing flowers, but also dyeing and matching colors.

4. Existing dyeing machine controllers will design different rise and fall temperature control curves, different ph change curves, in order to expect to obtain a similar coloring rate value change known from the laboratory.

5. Traditional laboratory testing of fastness to washing.

The above-mentioned existing dyeing process cannot directly sense the change process of dyeing residual liquid to convert the coloring rate to control and change the variable index factors that affect the coloring rate, such as temperature, ph value, dosing speed, water flow rate, and cloth movement. Speed, etc., therefore, the dyeing work is cumbersome, and the dyeing effect cannot reach the perfect ideal. It is indeed necessary to improve it.

The inventor is based on an innovative concept, based on years of professional practical experience in equipment development in this technical field, as well as active research and development thinking, and through countless actual design experiments, the invention was born.

The object of the present invention is to provide a dyeing machine control system that takes dyeing residual liquid as a control element.

The dyeing machine control system with dyeing residual liquid as the control element of the present invention directly senses the color depth or change speed of the dyeing residual liquid and converts the change process of the coloring rate to control the variable index factors that affect the coloring rate. For example, temperature, ph value, dosing speed, water flow speed or cloth moving speed, etc., in order to obtain better dyeing efficiency. Furthermore, the washing process can be controlled, and the color will return to the water level.

To achieve the above objective, the present invention includes a dyeing machine, a dyeing rate measuring unit, and a dyeing machine controller, wherein the dyeing rate measuring unit is connected to the dyeing machine, and the dyeing residue of the dyeing machine is drawn out and passed through After the coloring rate measuring unit measures the coloring rate, the residual liquid is returned to the dyeing machine; the dyeing machine controller is electrically connected to the dyeing machine and the coloring rate measuring unit, and the dyeing machine controller obtains the coloring The coloring rate transmitted by the rate measuring unit, and referring to the setting value of the coloring rate established by the controller of the dyeing machine, instructs and controls to change the variable index of the coloring rate of the dyeing machine.

The dyeing rate measurement unit directly reads the speed and amount of the dyeing residual liquid (coloring rate) of the dyeing element, and circulates the dyeing residual liquid of the dyeing machine to the coloring rate measuring unit to measure the coloring rate at a high frequency, which can be obtained at any time The dyeing rate data is used to precisely control and change the dyeing rate variable index of the dyeing machine, and the dyeing machine controller is used to control and change other variable index factors when the dyeing machine performs dyeing work to obtain better dyeing efficiency.

The following describes the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the drawings in the embodiments of the present invention. In the following description, many specific details are explained in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do so without departing from the connotation of the present invention. Similar promotion, therefore, the present invention is not limited by the specific embodiments disclosed below.

Please refer to FIG. 1 and FIG. 2, the dyeing machine control system of the present invention using dyeing residual liquid as the control element includes a dyeing machine 10, a dyeing rate measuring unit 20, and a dyeing machine controller 30. It will be explained in detail below:

The coloring rate measuring unit 20 is connected to the dyeing machine 10, and the dyeing residue of the dyeing machine 10 is drawn out, and the coloring rate is measured by the coloring rate measuring unit 20 and then sent back to the dyeing machine 10.

The dyeing machine controller 30 is electrically connected to the dyeing machine 10 and the dyeing rate measuring unit 20. The dyeing machine controller 30 obtains the dyeing rate transmitted from the dyeing rate measuring unit 20 and refers to the dyeing machine controller The coloring rate setting value established by 30 commands and controls the change of the variable index of the coloring rate of the dyeing machine 10.

The dyeing rate measuring unit 20 directly reads the color change speed or depth of the dyeing element dyeing residual liquid (coloring rate), and circulates the dyeing residual liquid of the dyeing machine 10 to the coloring rate measuring unit 20 at a high frequency. Color rate, the color rate data can be obtained at any time to accurately control and change the color rate variable index of the dyeing machine 10, and the dyeing machine controller 30 can control and change other variable index factors when the dyeing machine 10 performs dyeing work. Get better dyeing efficiency.

The foregoing is an introduction to the components of the present invention, and then the embodiments, features, and benefits of the present invention are introduced as follows:

Please refer to FIG. 3, in an embodiment, the color ratio measuring unit 20 is selected from one of a spectrophotometer, a colorimeter, or a spectrometer. The figure shows the composition and application principle of each part. The spectrophotometer , The colorimeter or the spectrometer is an existing product, and will not be described in detail.

In one embodiment, please refer to FIGS. 1 and 4 in conjunction. The dyeing machine controller 30 can instruct and control to change the coloring rate variable index of the dyeing machine 10 to temperature.

In Figure 4, L1 is the desired coloring rate curve, and L2 is the rising and falling temperature curve that varies with the coloring rate. First, the desired coloring rate curve L1 is set by the dyeing machine controller 30. Generally, the desired coloring rate For example, the curve L1 has a slope of 45 degrees as the ideal coloring rate. For safer coloring, the slope of the desired coloring rate curve L1 can be reduced by, for example, 30 degrees to extend the time. Or some fibers or colors can speed up the coloring speed, and the slope of the desired coloring rate curve L1 can be increased by, for example, 60 degrees, that is, heating can increase the temperature.

In this embodiment, when the coloring rate increases with time, controlling the speed of temperature increase is the main variable index factor of the coloring rate.

For example, when the dyeing residual liquid data input by the dyeing machine 10 is measured by the spectrometer or colorimeter of the dyeing rate measuring unit 20 to obtain a dyeing rate of about 50%, the temperature can be quickly increased to 90°C, but the dyeing rate is from 50% At ~98%, the temperature should be slowly increased from 90°C to 110°C. The last 1~2% coloring rate is left, and then it is quickly increased from 110°C to 130°C. Finally, the temperature is held for a period of time to fix the colored dye in the fiber.

Please refer to FIGS. 1 and 5. In one embodiment, the dyeing machine controller 30 can instruct and control to change the coloring rate variable index of the dyeing machine 10 to the ph value.

In Figure 5, L1 is the desired coloring rate curve, and L3 is the ph curve that varies with the coloring rate.

In this case, when the coloring rate increases with time, or when the speed of controlling the temperature increase cannot reach the main factor. It can be combined with a ph control factor to achieve the purpose of color rate control.

Please refer to Figures 1 and 5. In an embodiment, for example, the coloring rate of the dyeing residue data inputted by the dyeing machine 10 is measured by the spectrometer or colorimeter of the coloring rate measuring unit 20 to be about 25% At this time, the ph value can quickly drop from 10 to 7.0, but when the coloring rate is from 25% to 90%, the ph value should slowly drop from 7.0 to 5.0; the remaining 5 to 10% coloring rate, and then from 5.0 speed Decrease to 4.5; finally hold the temperature for a period of time at ph=4.5 to fix the dyes that have been colored in the fiber.

Please refer to Figure 1 and Figure 5. In an embodiment, and so on, if the time, temperature, or ph value cannot reach the slope of the color rate curve, you can add other control variables, such as dosing speed Speed, such as the speed of the dyeing auxiliary agent added to the dyeing machine 10 (for example, dye accelerator), and other control factors. The speed at which the dye accelerator is put into the dyeing machine 10 is used to control dyeing, so as to achieve a preset coloring rate curve Target slope.

Please refer to FIGS. 1 and 6, in one embodiment, the dyeing machine controller 30 can instruct and control to change the coloring rate variable index of the dyeing machine 10 to the degree of washing.

After the dyeing stage is completed, some "floating colors" that have not actually been dyed need to be removed to ensure the washing fastness. The process needs to drain the dyeing wastewater first, and then rinse with clean water. It is similar to that after washing clothes, it is necessary to drain the sewage that has been added with detergent for the first time, and then rinse it with clean water.

When the dyeing machine control system of the present invention takes dyeing residual liquid as the control element for dyeing work, the dyeing liquid is drawn out and circulated through the coloring rate measuring unit 20 to measure the color change of the residual liquid. Please refer to the horizontal line L4 shown in Figure 6. When the cloth is washed with clean water, the color is no longer darker, indicating that the washing time is sufficient and there is no need to waste time washing. Drain the sewage, and rinse again with clean water for a second time. If the degree of clean water becomes sewage is not obvious, it means that the cleaning effect has been reached, and the water can no longer enter, which saves unnecessary water waste. The advantages of the present invention compared with the existing traditional controller are as follows:

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
