This study involves the drying behaviour of a hot oil heated stenter used for drying and sizing of woven or knitted fabrics and modelling with a new empirical model developed. The suitability of the new model developed was compared with a theoretical model of First Order Kinetic model and 5 thin layer drying models selected from the literature. Statistical analyses between model and experimental data were evaluated by using MATLAB 2019a program as a benchmark. R2 values in the regression analysis were taken as the main criterion. In addition, SEE and RMSE data were evaluated in determining model suitability. According to the results obtained, in the case that the drying behaviour of the stenter was modelled with a First Order Kinetic model, R2 values between the model and experimental data were found to vary between 0.9933-0.9989. In the case of using 5 thin layer drying models selected from the literature, R2 values were found to range between 0.9740 and 0.9999 and the most suitable model among them was Approximation of Diffusion model. R2 values of the new empirical model developed were found to be between 0.9987 and 0.9999. Since the new model developed contains fewer model constants than other models available in the literature, it is concluding to provide practicality in researches on this subject and may display more sensitive results in determining thin layer drying behaviour.
