dc.description.abstract | This paper deals with the kinetics on the color changes of cellulose during heat treatment. The color of cellulose heated at 90-180℃ was measured by a spectrophotometer and expressed by CIELAB color parameters. The values of L* decreased and those of a*, b* and ΔE*ab increased at all the treatment temperatures. Several kinetic models, namely, the zero-order, first-order, second-order and autocatalytic model, were applied to the changes in the color values. Furthermore, the results of kinetic analysis using the best-fit model were compared to the results obtained from conventional kinetic models. It was suggested that the kinetic analysis using the best-fit model was the better way to accurately predict color changes during heat treatment. The values of apparent activation energy calculated from the changes of L*, a*, b* and ΔE*ab were 125, 124, 118 and 120 kJ/mol, respectively. These values were similar to the reported values calculated from other chemical or mechanical properties. | en |
