For this purpose, firstly, experimental drying behaviour of\r\nviscose bobbins was determined on an experimental dryer setup\r\nwhich was designed and manufactured based on hot-air bobbin\r\ndryers used in textile industry. Afterwards, drying models considered\r\nwere fitted to the experimentally obtained moisture ratios. Drying\r\nparameters were drying temperature and bobbin diameter. The fit\r\nwas performed by selecting the values for constants in the models in\r\nsuch a way that these values make the sum of the squared differences\r\nbetween the experimental and the model results for moisture ratio\r\nminimum. Suitability of fitting was specified as comparing the\r\ncorrelation coefficient, standard error and mean square deviation.\r\nThe results show that the most appropriate model in describing the\r\ndrying curves of viscose bobbins is the Page model.","references":"[1] A.S.
