It is used in textile quality control laboratories to determine the color and pilling fastness of samples through friction. Samples can be tested wet and dry. Samples are rubbed against a dry, undyed cotton companion fabric. The color uptake rate of the companion fabric is determined according to the staining gray scale. The device has two separate models: manual and motorized. The motorized model is used when a high number of tests are required. It stops automatically after the desired number of tests. A 25mm tip and a 22N weight can be used if required.
