The dyeing and finishing process creates a 50% value increase for the textile industry. It is also the most energy-consuming industry. Taiwan is a major manufacturing site for functional textiles. In response to brand pull, carbon footprint, clean process and energy saving requirements, it is bound to lead to process and technical energy saving. The cooling water and waste heat in the dyeing process of the dyeing machine of the general dyeing and finishing plant are not fully recovered and reused, resulting in a large amount of energy consumption. Therefore, the dyeing cooling water reuse technology is established to reduce energy consumption Establish boiler water supplement technology to use hot water with thermal energy to save energy, reduce costs and improve quality, reduce waste heat emissions and improve quality, so that the industry process saves more energy.
