High–temperature dyeing of polyester with true solutions of crude dyes and dispersant–free disperse dyes dissolved in the presence of a surfactant mixture has been simulated with the help of two mathematical models. The dyeing behaviour, i. e. the kinetics of exhaustion and of dye distribution in the fibre have been evaluated for nine hypothetical dyes. In the first method kinetics of hypothetical crystalline modifications of three Terasil dyes and in the second method for hypothetical surfactants have been studied. For both methods the laws governing the dyeing behaviour have been formulated. The advantages and disadvantages of the methods and the scope for implementing them are discussed.
