  Fabric Rubbing Test Results


What is rubbing test in fabric? A fastness is a place, such as a castle, which is considered safe because it is difficult to reach or easy to defend against attack. Color fastness to rubbing test is designed to determine the degree of color which may be transferred from the surface of a colored fabric to a specify test cloth for rubbing (which could be dry and Wet). Rubbing or crocking fastness is the transfer of dyed textile material’s color from its surface to an adjacent area by the same fabric or other surface (normally bleached cotton fabric) principally by rubbing. It is tested using a crockmeter. It may be either hand-driven or motorized. Depending on the kind of fiber, especially its tensile strength, small abraded colored fiber particles cause the staining effect on the partner textile. Coarse fiber particles are not taken into consideration by the determination of the crocking fastness rating. If the dyestuff involved is water soluble and not sufficiently fixed on the fiber, this can also be the reason for staining. But even dyeings with the best wet properties, for example vat dyeing, have limited/restricted wet crocking fastness because of cellulose fiber abrasion.
