GB-T 3920 Textile - Color Fastness Tests - Standard Test Method for Color Fastness to Rubbing

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of GB-T 3920 testing. Color fastness to rubbing test is a test to determine the long-term use quality of textile products. The purpose of this test is to determine the level of color that can be transferred from the surface of a colored fabric to a test cloth by dry and wet rubbing.

The rubbing fastness mainly depends on the nature of the color and the shade depth. Each color is a pigment by nature and has rubbing fastnesses. Colors such as black, red, burgundy, navy blue have poor color fastness due to their chemical structures. For example, black is a carbon-based color and the particle size of carbon is larger than other colors. Therefore, its friction properties are low.

The properties of red and blue colors are similar. Therefore, in order to improve the fastness properties of the colors, more binders are added to the paint while it is being prepared. Meanwhile, the structure of the fabric also affects the fastness properties.

These standards describe methods for determining the color resistance of textiles to rubbing, staining, and staining of other materials.
