Researchers developed a mathematical model to predict the uneven levelness in a dyed yarn package and used the model and in-line measurements of dye liquor concentration and liquor temperature feedback control to achieve and maintain a set rate of dye exhaustion in a pilot scale dyeing machine. The system functions for both all-in and continuous addition control systems. The mathematical model uses a mass-balance approach to calculate the dye present in the yarn package and in the liquor and differential equations to describe the rate of dye adsorption. The system recognizes different dye bath conditions and adapts target values to achieve the optimum exhaustion profile. 6 refs.
