摘　　要：The grey system theory, with the characteristics of fewer modeling data and higher accuracy, was employed to model the batch dyeing process for the purpose of accurate online control. The GM（1, 1） and GM （0, N） models of the grey system theory were discussed for their feasibilities of modding for batch dyeing process. The combination of direct dyestuff Fast Red F3B on cotton was chosen as a representative of the common dyeing method for describing the modeling process. Firstly, the GM（ 1, 1 ） model and the GM（1, 1） combined with GM（0, N） model were employed to model the equilibrium percentage of dyeing uptake rate. Secondly, an integrated dyeing uptake rate model with three factors （ temperature, salt concentration, and pH） was established based on the adsorption rate equation. Experimental results show that this model has higher accuracy and beetler generalization ability, which can predict the results of batch dyeing process. Due to the application of grey system theory, the model has a lot of advantages, such as being easy to determine the parameter value and small amount of calculation. So it can also be suitable for the same type of combination of dyestuff-fahric by changing the parameters value only.The grey system theory,with the characteristics of fewer modeling data and higher accuracy,was employed to model the batch dyeing process for the purpose of accurate online control.The GM(1,1) and GM(0,N) models of the grey system theory were discussed for their feasibilities of modeling for batch dyeing process.The combination of direct dyestuff Fast Red F3B on cotton was chosen as a representative of the common dyeing method for describing the modeling process.Firstly,the GM(1,1) model and the GM(1,1) combined with GM(0,N) model were employed to model the equilibrium percentage of dyeing uptake rate.Secondly,an integrated dyeing uptake rate model with three factors(temperature,salt concentration,and pH) was established based on the adsorption rate equation.Experimental results show that this model has higher accuracy and better generalization ability,which can predict the results of batch dyeing process.Due to the application of grey system theory,the model has a lot of advantages,such as being easy to determine the parameter value and small amount of calculation.So it can also be suitable for the same type of combination of dyestuff-fabric by changing the parameters value only.
