Abstract: AN expert system for dyeing cotton fabrics with reactive dyes that integrates the dyeing expertise, practical experiences and data processing technologies and has the functions of query, analysis, recommendation, inference, record, education and training. The system is applicable for the dyeing mills dyeing various cotton fabrics and provides the quantified compatibility index of any reactive dye combination, recommends the optimal recipe combination based on the change of dyeing liquor ratio and design dyeing process online based on the structure specifications of fabrics and the parameters of dyeing machines.

Abstract: This automatic admixtrue dosing and pH value control batch dyeing system is comprised of a pH value gauge, a thermometrer, a pump for adding chemicals, a drain valve, a chemical tank, a continuous action depth gauge, a mixing valve, and a chemical input valve. The controller is designed to proceed according to several chemical graphs located inside the controller. The user, depending on the requirment of chemical dosing and pH value control, sets the time for inputting chemical and a predetermined pH value. When this is done, the controller, according to the selected chemical graphs and target pH values, operates the chemical pump, the mixing valve, and the chemical dosing valve. The chemical module flow into action, and the dye liquor in the chemical tank flow into the dye machine. The depth gauge, the pH gauge and the thermometer measurs the volume of liquid in the chemical tank, and the pH value and temperature of the dye liquid in the dye machine.
