Abstract:

Aiming at no theoretic model to guide the temperature setting of chamber and no reasonable temperature setting of the drying chamber of a setter energy loss of the stenter, in order to reduce energy consumption of fabric heat setting, an optimized method was proposed. The distribution of air temperature and pressure in chamber was simulated, and the uniformity of them in the fabric heating position were verified by the Fluent. By the analysis of the fabric thermodynamic characteristics, an estimation model is constructed to express the fabric temperature in time in the process of fabric heat setting, and key parameters are identified by experiments. With the target of minimum energy consumption, the particle swarm optimization was used to obtain the optimized temperature value of chamber. Heat setting experiments of the polyester fabric were carried out, with the results showing that this estimation model can match the fabric practical temperature in the heat setting period, and the optimized temperature value is effective for guiding the temperature setting of the drying chamber to save energy for the stenter.

Key words: heat setting, estimation model of fabric temperature, chamber temperature, energy consumption, stenter
