Abstract
Due to increase in production of the domestic textile industry, energy consumption in textile industry is still growing. Traditional dyeing machine has high temperature and pressure. Accordingly, it uses an indirect cooling system that utilize a heat exchanger to cool after the dyeing. However, this indirect cooling system consumes a great deal of water, takes prolonged periods of time to process and, most importantly, because of the condensing of the dye at the cooling stage requires further energy in reduction cleaning and washing process. Therefore, in this paper, we propose a direct cooling washing machine that replaces the traditional indirect cooling system to provide coolant into the dyeing machine. The newly proposed direct cooling washing machine will still use parts of the traditional dying but will be able to skip the cooling as well as the reduction cleaning and washing process, resulting in less processing time and lower energy consumption. Also, we made a prototype. The prototype was applied to dyeing machine to test the direct cooling washing machine's ability and dyeing property. Additionally, we compared indirect cooling washing machine with direct cooling washing machine about ability, material and energy saving assessment.
