Özet
Inevitable after most dyeing or/and finishing processes, drying is a time consuming, energy intensive and expensive process and constitutes one of the major cost elements among the textile finishing operations. The drying behavior of wool based yarn bobbins for different drying air pressures at a constant drying air temperature was simulated by empirical and semi-empirical drying models available in the literature. For this purpose, firstly, experimental drying behavior of wool bobbins was determined on an experimental bobbin dryer setup which was designed and manufactured based on hot-air bobbin dryers used in textile industry. Then, drying models considered were fitted to the experimental data. The fit was performed by selecting the values for constants in the models in such a way that these values make the sum of the squared differences between the experimental and the model results for moisture ratio minimum. Suitability of fitting was specified as comparing the correlation coefficient, standard error and mean square deviation. The results show that the most appropriate model in describing the drying curves of wool based yarn bobbins is the Logarithmic model. The results also show that the drying air pressure has a significant effect on drying.
