In the traditional textile printing and dyeing process, the cloth needs to be pad-dyeed. For example, when continuously pad-dyeing reactive dyes, it is necessary to pad-dye reactive dyes and alkali agents in the same bath; However, it is well known that reactive dyes will decompose when they encounter alkali. If they are in the same bath, it will easily cause the hydrolysis of reactive dyes in the trough, and the color difference between the head and tail of the product will appear. Disperse dyes and alkaline or cationic additives are in the same bath , It will also cause problems such as flocculation, agglomeration, and decomposition.

For a long time, the way to solve this problem in the industry is to seek alkali-resistant reactive dyes at high cost, or various auxiliaries that can be compatible with disperse dyes in the same bath. Some people also use two or more metering pumps to measure and transport the solutions that are not easy to be in the same bath, so that they can be quantitatively input into the same trough, so as to reduce the residence time of the two solutions in the same trough, but this cannot cure the two Interaction of solutions in the same trough.

Some people also use two sets of rolling systems to press two different solutions respectively. However, when rolling the second solution, part of the first solution carried on the surface of the cloth will fall off or dissolve into the second solution. , will also affect each other, and ultimately affect product quality.

Therefore, in order to solve the above-mentioned technical problems, finding a kind of continuous dyeing equipment has become an important subject studied by those skilled in the art.

Further, the continuous steaming device 4 is a heating large wheel type continuous steaming device 4, and the heating large wheel type continuous steaming device 4 includes a large-diameter heating wheel 19, and a conveyor belt device coated on the outer surface of the large-diameter heating wheel 19 , the conveyor belt device includes a high temperature resistant conveyor belt 20, a conveyor belt support device, and a conveyor belt correction device; a part of the high temperature resistant conveyor belt 20 is coated and pressed on the outer circular surface of the large diameter heating wheel 19, and the high temperature resistant conveyor belt 20 and the large A continuous and closed cloth conveying passage is formed between the diameter heating wheels 19, the front of the cloth conveying passage is the entrance of the cloth conveying passage, the rear of the cloth conveying passage is the cloth conveying passage outlet, and the cloth enters the cloth conveying passage from the entrance of the cloth conveying passage, Leave the cloth conveying channel from the outlet of the cloth conveying channel.

It should be noted that, after the cloth containing dye liquor and auxiliary agent enters the continuous steaming device 4, it is heated by the large-diameter heating wheel 19. During the heating process, the cloth is pressed between the large-diameter heating wheel 19 and the high-temperature-resistant conveyor belt 20, and the cloth The carried moisture becomes steam after being heated, and exists between the large-diameter heating wheel 19 and the high-temperature-resistant conveyor belt 20, that is to say, the cloth is surrounded by high-temperature water vapor, dyes and auxiliary agents, and this high-temperature water vapor can Wetting and swelling fibers have certain plasticizing effect on fibers, increase the kinetic energy of fiber molecules, accelerate the movement of fiber molecules, expand the molecular structure of fibers, increase the molecular gap, and facilitate the entry of dye molecules into the gap between fiber molecules .

When the dye is sublimated at high temperature, its dye molecules are coated between the large-diameter heating wheel 19 and the high-temperature-resistant conveyor belt 20, and will not volatilize or escape into the atmosphere. The molecules are in close contact, and the dye molecules are fully mixed in the high-temperature water vapor during the entire heating process. Under the mediation of high-temperature water molecules, the dye molecules are more likely to enter the gaps between the fiber molecules, so that the fabric fibers can absorb and accept as much as possible. Dye molecules, so dyeing by the method of the present invention has a high utilization rate of dyes, and the color yield is relatively deep, saving dyes and reducing the burden of subsequent washing.

Further, the outer circumference of the large-diameter heating wheel 19 and the high-temperature-resistant conveyor belt 20 coated on the outside of the large-diameter heating wheel 19 is provided with several groups of pressure wheels, and the cloth between the high-temperature-resistant conveyor belt 20 and the large-diameter heating wheel 19 Apply pressure intermittently. The dye runs along with the cloth, the temperature goes from low to high, and the kinetic energy of the dye molecules increases from small to large. The dye molecules pass through several sets of pressing wheels intermittently as the cloth travels. The fabric is intermittently pressed by each set of rollers while it is wetted and swelled by high-temperature water vapor. For the microstructure of the fiber in the high-temperature swelling state, it is equivalent to several breathing movements. When rolling, the molecular gap of the fiber shrinks, and when it is not rolled, the molecular gap of the fiber becomes larger, so that a negative pressure is formed in the molecular gap, and the dye molecules are rolled (absorbed) into the molecular gap of the fiber. Due to the low temperature at the beginning, Only smaller dye molecules can be rolled into the molecular gap of the fiber. With continuous operation, the temperature of the fiber, water and dye molecules continues to rise, the molecular gap of the fiber becomes larger, and the kinetic energy of the dye molecule becomes larger. The larger dye Molecules can also enter the molecular gap of the fiber. In the later stage, due to the highest temperature, the molecular gap of the fiber becomes the largest, and the disperse dye molecules reach the sublimation state. At this time, the disperse dye molecules are almost all sublimated into single-molecule gaseous structures. Therefore, the disperse dye molecules can be absorbed into the molecular gap of the fiber as much as possible under the negative pressure of the pressure wheel on the fiber microstructure. For reactive dyes, in a continuous and closed high-temperature environment, under alkaline conditions, reactive dyes and fabrics are more likely to produce covalent bonds, which improves the color fixation rate of reactive dyes on fabrics. The improvement of color fixing rate means the reduction of floating color, the reduction of post-processing burden and the improvement of color fastness.

The steaming temperature of reactive dyes is generally controlled at about 160°C. In order to avoid the large difference between the working temperature and the ambient temperature, resulting in color difference between the left, middle and right, an insulation layer can be installed on the two end faces of the large-diameter heating wheel 19. The surface of the two ends of the diameter heating wheel 19 or inside are provided with supplementary heating and control devices such as electric heating tubes.

Further, in order to prevent the water vapor between the large-diameter heating wheel 19 and the high-temperature-resistant conveyor belt 20 from escaping from both sides of the high-temperature-resistant conveyor belt 20, the two sides of the high-temperature-resistant conveyor belt 20 that are close to the large-diameter heating wheel 19 wheel surfaces are provided with a direction Large-diameter heating wheel 19 is provided with a protruding retaining bar (retaining ring) in the direction of the wheel surface, and the supporting guide wheel of large-diameter heating wheel 19 and high-temperature-resistant conveyor belt 20 is provided with a groove corresponding to the retaining bar (large-diameter heating wheel can also be used) 19 and the edges of the two ends of the support guide wheel of the high temperature resistant conveyor belt 20 are used as grooves), and the retaining bars are engaged in the grooves during operation. It is equivalent to the meshing of the V-belt in the corresponding pulley, which can effectively prevent water vapor from escaping from both sides, and the bar and the groove simultaneously play the role of limiting and correcting the deviation of the conveyor belt.

It is also possible to increase the diameters of the two ends of the pressure wheel surface, or make it commonly known as "middle and low". The water vapor between the high-temperature conveyor belt 20 and the large-diameter heating wheel 19 does not escape from both ends.

It is also possible to design a retaining ring protruding from the wheel surface at both ends of the large-diameter heating wheel 19. The inner edge of the preferred retaining ring is a bevel, and the left and right bevels form a pulley similar to a V-belt, and the high-temperature-resistant conveyor belt 20 is similar. A V-belt, the two ends of the high-temperature-resistant conveyor belt 20 are arranged in cooperation with the slope of the retaining ring, which helps to keep the water vapor between the high-temperature-resistant conveyor belt 20 and the large-diameter heating wheel 19 from escaping from the two ends.

In a word, the water vapor between the high-temperature-resistant conveyor belt 20 and the large-diameter heating wheel 19 does not escape from both ends by designing retaining strips or retaining rings on both sides of the high-temperature-resistant conveyor belt 20 and the large-diameter heating wheel 19 That's it.

It should be noted that the high temperature resistant conveyor belt 20 should not only be able to withstand high temperature, but also choose the material of the conveyor belt that is not easy to absorb dye molecules. The preferred material for the working surface of the high temperature resistant conveyor belt 20 is silica gel or Teflon or wool blend or DuPont KEVLAR Materials such as fiber or meta-aromatic polyamide fiber (Nomex) or stainless steel can withstand high temperature and are not easy to adsorb dye molecules. The large-diameter heating wheel 19 is heated by electric heating or thermal oil or steam.
