Heat and mass transfer through fabric: a model for fabric drying with heated cylinders
For textile manufacturers, this model offers a tool to optimize energy-intensive drying processes, though it is an incremental improvement over existing drying models.
A mathematical model for fabric drying with heated cylinders under low pressure was developed, predicting drying time and residual moisture content with parameters estimated via nonlinear least squares, validated on real-world data from an Italian textile company.
Textile drying is a key operation in the textile production cycle as it represents one of the most energy-intensive stages and plays a critical role in determining both product quality and overall process efficiency. In this work we propose a mathematical model for the drying process of a generic textile material using heated cylinders, operating under low-pressure conditions. The model's parameters are estimated by nonlinear least squares regression. Given a specific fabric, the developed model allows to predict the drying time and the residual moisture content. The model is validated using real world data provided by a major Italian textile company.
