Electronic Rubbing Colour Fastness Tester

Electronic rubbing colour fastness tester is designed with a base, rubbing rotation mechanism and a counter. Fix the specimen and sand paper with the specimen clamp on one side of the base. Rotate the knob to rub the friction head with the white cotton cloth against the specimen in reciprocation motion with specified strokes.

After ten times of friction between the white cloth and the specimen, assess the color transfer to the white cloth with a gray scale and the stability of dyed fabric specimen or surface coating so as to provide reference data for material assessing and selection.

Applications

Electronic rubbing colour 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.

Technical Parameters

Test Procedures

1. Sample Preparation

Prepare samples of appropriate size according to testing standards or customer requirements, ensuring that the sample surface is flat and free of defects.

2. Setting Test Parameters

Set the test parameters of the electric friction color fastness tester according to testing standards or customer requirements, such as friction speed, pressure, and number of cycles.

3. Performing the Friction Test

Fix the sample onto the sample clamping device, start the electric drive device, and allow the friction head to rotate or reciprocate on the sample surface. During the test, observe the color change of the sample.

4. Evaluating Test Results

Evaluate the degree of color change of the sample according to testing standards or customer requirements, and provide the corresponding test results. A gray scale or standard staining gray card is usually used to assess the color fastness to rubbing grade.
