Calculation Method of Carbon Emission in Production Process for Optimization of Polyester Low Elastic Yarn Process

摘要

Aiming at the problems of many parameters and energy consumption fluctuation in the production process of polyester low elastic yarn, firstly, the mechanism of energy consumption fluctuation and coupling of various parameters was analyzed. Based on the carbon footprint theory, an energy consumption analysis model of polyester low elastic yarn process was constructed around the production process of polyester low elastic yarn. Furthermore, the carbon footprint accounting was carried out for the process flow, and then the carbon emission and key process parameters were fitted, on the basis of the function relationship between the parameters, a process optimization model of polyester low elastic yarn based on the combination of signal-to-noise ratio orthogonal test and comprehensive weighting VIKOR method was constructed. Finally, through the experimental verification and analysis, the results show that the model reduces the carbon emission of the production process by 4.58% compared with the initial state by optimizing the key process parameters of polyester low elastic yarn production. On the premise of reducing energy consumption, the quality of polyester low elastic yarn has been improved.
