Abstract:

In order to solve the problem of no reasonable optimization of the production process due to the overlooking dynamic energy consumption in the differential fiber production process, the production process and energy consumption of the differential fiber production process were firstly analyzed, and the energy consumption metering and accounting model based on carbon footprint was built. Then, the carbon emission function based on green low carbon was designed based on the energy carbon consumption, material carbon consumption and process carbon consumption. Furthermore, the polyester low elastic production was selected as the research object, and a process optimization model of the polyester low elastic filament based on carbon emission accounting was designed. Finally, on the basis of historical data, the process optimization model was solved. The results show that the model optimizes the key process parameters of the differential fiber production process, and the carbon emission of the polyester low elastic filament production decreases by 13.35%.

Key words: polyester low elastic filament, process optimization, differential fiber, carbon emission function
