Digital Twin for Energy Optimisation in Finishing
topic
Finishing process digital twins model heat and mass transfer in stenter drying, padding mangle wet pickup, and chemical fixation as functions of process settings and fabric properties, using the validated thermal model to identify the minimum energy settings that achieve fabric dryness and finish cure specifications, enabling energy consumption reduction of 15 to 30 percent through systematic optimisation of stenter temperature, fan speed, and chain speed for each fabric type.
Role
Reduces stenter and finishing range energy consumption through model-based optimisation of process settings that identifies the energy-minimum operating conditions satisfying product quality constraints, with digital twin energy optimisation providing more substantial and systematic energy savings than empirical trial-based optimisation by exploring the full multidimensional setting space that practical process trials cannot cover comprehensively.
