The process of extracting technological contaminants from textile materials is considered as a mass transfer process, for the intensification of which pulsed exposure to an ultrasonic field is chosen.
A lightweight fabric was selected for the study in order to eliminate the influence of surface density and fabric thickness on the kinetics of the process. The results of an experimental study of the kinetics of the extraction of so-dium hydroxide during washing after mercerization of a light standard cotton fabric are presented. The studies were carried out in laboratory conditions on a model installation with a different washing bath module without intensification and with the use of ultrasonic exposure as an intensifier. At the same time, the optimal distance from the ultrasound source to the washed tissue was determined based on previous studies. Exposure to ultrasound sig-nificantly reduces the duration of the process, especially at the initial stage. Equations for approximating the kinet-ics curves of sodium hydroxide extraction from cotton fabric without intensification and with intensification by ul-trasonic action are obtained, and their parameters are determined. The correlation of calculated and experimental data is acceptable for approximate kinetic calculations. The obtained equations can be practically used in engi-neering practice for a preliminary assessment of the duration of the process of extrusion-washing of cotton fabrics belonging to the group of light cotton fabrics from alkali in various modules of the washing bath.
