Since its birth, the overflow dyeing machine has taken a big step towards environmentally friendly dyeing with its relatively low liquor ratio (about 1:15). 1:25 or more. At present, although the bath ratio of conventional overflow dyeing machines has been reduced to 1:7-1:8, it is still high, and the dyeing cycle is also long, which cannot meet the requirements of ecological and environmental protection, and the production cost is also high. Due to the large size of the bath, the fabric will carry a lot of water during the running process, which will increase its own weight and easily cause excessive stretching and fluffing. Therefore, further reducing the bath ratio of the dyeing machine, reducing environmental pollution, shortening the dyeing cycle, realizing eco-friendly dyeing, and reducing production costs are the key to improving product quality, as well as the development direction of dyeing technology and the sustainable development of the printing and dyeing industry in the 21st century. Key factor.
