Product Application

Electric Friction Color Fastness Tester is suitable for dyeing of fabrics - leather by rubbing the degree of discoloration, test method is based on the dry or wet white cottoncloth, wrapped in friction cone, then rubs caught in the trial stage of the test piece, you can assess color fastness grade.

Electronic Crockmeter/Rubbing Fastness Tester is used to determine the colour fastness of cotton, chemical fiber, blended, other coloured fabrics and leather to dry or wet rubbing. Motorised for frequent use and long run tests. A piece of dyed test cloth and a piece of white cotton cloth are rubbed against each other though the tester in a specific pressure and stroke.
The color fastness of the sample is graded by comparing the coloring of the white cotton with the gray scale. Fitted with digital electronic presettable counter for strokes.
