Cotton Fabric Dyeing Formulation Optimization

In order to achieve the optimal design for cotton fabric dyeing formulation and its technological parameter, a new method with IHA(intelligent hybrid algorithm) was introduced. Firstly, a mathematical model of optimal fabric dyeing formulation was established. And then GA(genetic algorithm) was improved by the essential operations such as self-adaptive adjustment and fitness similarity discrimination strategy. Finally, combining the improved GA with the simulated annealing algorithm, IHA was applied into the solution of the optimal model. The results show that the model is reliable and efficient. The convergence rate, and the search capability and stability of IHA are improved. The dyeing formulation and technological parameter obtained by IHA are better than GA: the chromatism decreases by more than 6.47%;and the cost reduces by more than 2.16%. This method provides theoretical guidance for quality control and rapid parameter setting of dyeing production process.
