Heat-setting process is one of the major energy-consuming unit in dyeing industry.Firstly

based on stereotypes of the physical structure and process principles

model of energy consumption and the key factors of the process is derived using Newton〖DK〗’s heat balance and heat exchange formula.Then

in the Matlab/Simulink software

the following model is constructed.Finally

after the conversion of the energy model into the optimization problem of minimum energy consumption

particle swarm optimization algorithm is introduced to solve them.Simulation of industrial data shows that the proposed energy consumption model is consistent with on-site process and particle swarm optimization results can provide a reference and guidance for the operation.
