The beam dyeing machine rolls the fabric on the reel of the porous drum, fills it in a pressure cooker, and uses a high-lift, high-flow professional chemical pump to transfer the dyeing liquid flow forward and backward during the circulation process in the system. Alternate transformation, so that the dye solution completely penetrates the rolled fabric, and is dyed in a high-temperature, high-pressure dye bath. The warp beam dyeing machine is suitable for sensitive fabrics that are easy to change, easy to curl, and easy to slip.
Before dyeing with the warp beam dyeing machine, at first the fabric will be rolled on the inner drum of the warp-beam machine with a winder. In order to increase the friction of the fabric and make rolling easier, it is generally necessary to pass water when rolling, and the amount of liquid carried by the fabric is adjusted by the pressure of the padding machine and the speed of rolling. The quality of the curl has a great influence on the dyeing. When rolling, it is not that the tighter the roll, the greater the tension, the better the effect. When rolling, try to keep the speed constant.
1. Applicable fabric types
Warp-fabric such as taffeta, Lycra, Oxford cloth, flat fabric such as nylon rich silk and triangular bright silk, also suitable for nylon 66, silk, non-woven fabric and other fabrics.
2. Dyeing principle
The dyeing of the warp beam dyeing machine is mainly that the dye liquor is dyed on the fabric during the circulation process of the dye vat and the dosing barrel under the action of the pump. The warp beam dyeing machine has two dye liquor circulation processes, large and small. The so-called “big cycle” means: after the dye liquid is heated by the heat exchanger, it passes through the dye liquid injection port under the action of the main pump, completely penetrates the fabric under the action of the pressure difference, and then enters the heat exchanger Carry out the next cycle; the so-called “small cycle” refers to: the dye liquor in the tank expands in volume during the heating process, the dye liquor enters the medicine barrel, and then enters the nozzle of the dye liquor under the action of the dosing pump .
REHOW experts tell you the difference between warp beam dyeing machine and general dyeing machine
Due to the different characteristics of long-fiber, non-woven fabrics and silk fabrics, long-fiber and non-woven fabrics will produce a lot of entanglement during the dyeing process; while silk fabrics will hardly have fibers from the dyeing process. The surface of the fabric peels off. Therefore, the structures of these two types of warp beam dyeing machines are also different. How to pay attention to the mechanical influence of beam dyeing machine during dyeing?
There are a few things to consider:
1. Main pump
The power of the main pump directly affects the penetration ability of the dye solution. If the power of the main pump is too small, the dye solution cannot completely penetrate the fabric on the inner drum, and large areas of dyed flowers or gradual colors will appear on the fabric surface; When the liquid injection port is used, the spraying pressure will cause the cloth to flee. Therefore, when selecting the main pump, the above phenomena must be considered, and a reasonable pipeline should be designed accordingly to maximize the efficiency of the main pump and minimize energy consumption.
2. Sealing
Since the warp beam dyeing machine is a high-temperature and high-pressure dyeing machine, if air enters during the dyeing process, the following abnormalities will occur:
Oxidative decomposition of dyes. When the temperature is higher than 80°C, dyes are easy to oxidatively decompose when exposed to air, especially reactive dyes.
If the air enters the rolled fabric with the dye solution, the surface of the fabric will not be colored, air spots will be generated, and the fabric surface will be abnormal.
If air enters during scouring and bleaching, the surface of the fabric will be oxidized and brittle, the tear strength will decrease, and coloring will be abnormal during dyeing. How to solve the above problems, first of all, the dyeing machine manufacturer is required to go through flaw detection inspection of all weld seams during welding, and there should be no mechanical flaws; secondly, during the installation process, the sealing of each flange and joint should be good; finally, in the dyeing machine During the dyeing process of the factory using the dyeing machine, it is necessary to regularly check the tightness of each joint to prevent the screw from being loosened due to motor vibration during the production process and affecting the seal.
