Recently, the printing and dyeing industry has ushered in important innovations in mechanical process applications, with the optimization and upgrading of multiple process solutions, providing a new path for energy conservation and efficiency improvement in the industry.
In core printing and dyeing processes such as dispersion, activity, and acidity, the adaptation and combination of different heat sources and equipment have become the focus of attention. Taking the dispersion process as an example, enterprises can choose thermal oil, medium pressure steam, or natural gas as heat sources according to actual conditions. The scheme of using natural gas heating furnace has an energy consumption of 9m ³/h x 2 units. Compared with traditional methods, it not only meets the requirements of process temperature of 175 ° -185 ° C and 7-minute steaming time, but also has more flexibility in heat source utilization.

There have also been new breakthroughs in active and acidic processes. In the active process, the external saturation generator hybrid system can efficiently utilize ordinary steam, with a steam consumption of 350kg -550kg/h, and can stably output a process temperature of 102 °± 1 ° C, ensuring a 10 minute steaming process; The acidic process achieves precise temperature control through a built-in saturation generator with a steaming time of 40 minutes. Different heat sources (ordinary steam, heat transfer oil, etc.) are adapted to provide multiple options for energy saving for enterprises (such as heat transfer oil scheme with energy consumption of up to 150000 kcal). The upgrade of printing and dyeing machinery technology this time will help the industry take a crucial step towards green production and efficient operation, and promote sustainable development of the industry.
