Temperature is an important factor affecting the dyeing effect of dyeing machine

There must be many reasons that affect the quality of a product, but there must be a primary and secondary one. The quality of dyeing machine dyeing directly affects the appearance of the fabric. Therefore, the dyeing process of the fabric must be strictly controlled.

There are many factors that affect the dyeing effect, mainly including the temperature, concentration, and time of the dyeing solution. Among them, temperature is one of the important factors that affect the dyeing effect. Generally speaking, the high temperature increases the kinetic energy of the fuel. At the same time, due to the expansion of the fiber, the internal pores increase, which facilitates the adsorption and diffusion of the fuel, which speeds up the dyeing, but the temperature is too high. When it is high, the kinetic energy of the dye particles is too large due to the excessively large limiting pores, which will cause the fuel part dyed with the fiber to be re-dissolved into the dyeing solution and affect the dyeing effect. Therefore, the temperature control process of the dyeing tank must strictly meet the corresponding work requirements .

At present, the temperature control of domestic dyeing machines is mostly manually operated. Workers make judgments based on the readings of the thermometer and use experience to heat or cool. This causes large subjective errors. The dyeing process cannot strictly follow the process curve for heating, heat preservation and heating. Cooling down results in more color patterns and color differences on the cloth; other dyeing factories have automatic temperature control, but simply control the heating valve and cooling valve on and off. When the temperature reaches the specified temperature value, the corresponding valve will be closed, and the dyeing The temperature control in the process cannot strictly follow the process curve, and the temperature of the dyeing is transmitted to the control room through the sensor, and the temperature control is realized in the control room. After the system is controlled, the online and timely control cannot be realized. At the same time, the signal transmission line There are also more, resulting in poor structure dispersion, large construction investment, long period, inconvenient maintenance, and susceptible to interference.
