Energy conservation and environmental protection trends are obvious

Pre-treatment is the most water-consuming part of the printing and dyeing process. The implementation of the process of reducing water consumption and the reduction of water consumption and chemical consumption have become the mainstream trend of development. In addition, printing and dyeing equipment manufacturers are also paying more attention to controlling the dyeing bath ratio in the dyeing process. For example, Precise dye flow control and cloth separation technology to reduce the dye bath ratio and other processes have greatly improved the energy saving and environmental protection features of the equipment.
