The exchange mode of different dye liquor in the dyeing machine of overflow dyeing machine
Sep 12, 2021
After a long time in the overflow dyeing machine, dip dyeing: The fabric is also immersed in the dye liquor. Promote the dye to be fixed on the surface of the textile. This dyeing method is suitable for all kinds of textiles, especially many textiles that cannot accept tension or are pressed. However, this dyeing method, the more commonly used batch production method, although the overall operation will be relatively simple, but the production efficiency is not high.
The overall form and air flow are different, but both use two nozzles, air pressure penetration. One is a pure air jet nozzle, and the other is a liquid flow nozzle. When the fabric is dyed, it is necessary to pass through the liquid flow nozzle so that the effective exchange between the dye and the liquid takes place, and then it is directly extracted from the dyeing liquid. The position of the cloth roller directly enters the airflow nozzle. The main airflow has an effect on the fabric on the dye liquor, which is the pressure of penetration. Therefore, when the dyeing machine starts to pull the fabric, it is also necessary to remove the dye liquor. Effectively improve the speed of diffusion.
The dye liquor of the overflow dyeing machine also needs to pass through the nozzle and atomize the airflow. After the atomization treatment, it will be directly dispersed in the entire airflow, and then use the airflow of the atomized dye solution to exchange all the fabrics that need to be dyed, and effectively ensure that the fabric is traction and circulation. However, during the entire exchange process, the atomization will have a relatively large contact area for the dye liquor on the fabric, and the penetration of the fibers contained in the fabric is also very strong. The fibers in the dye liquor can be quickly carried out to a large extent. diffusion. Judging from the current use in the market, the atomization of airflow is widely used in the form of dyeing, and the effect of use is also good.
Overflow dyeing machine pad dyeing: In fact, the fabric is directly impregnated for a short period of time, and then it is pressed back and forth with a roller to ensure that the dye can be more evenly distributed on the surface of the fabric, and finally achieve the dyeing effect and purpose The big advantage of this method of dyeing is that it has a higher normal efficiency, but it is more suitable for dyeing woven fabrics.
