An apparatus is described for providing controlled mechanical agitation of chopped fibre in detergent liquors on a laboratory scale, employing relatively low liquor: fibre ratios. Thermostatic tenipertlt are control is provided, and by means of calibration graphs, temperature‐time conditions can be selected to follow industrial practice. An estimate is given of the accuracy of speed and temperature control.
