In the production and inspection process of fabrics and garments, color fastness to rubbing is crucial to the service life of the fabric, the wearing experience of consumers and the appearance quality of the fabric.

So what is color fastness to rubbing?

The color fastness to rubbing refers to the color loss of the rubbed part of the textile when it is rubbed under a certain pressure. The color fastness to rubbing test is to check the degree of staining of the cotton cloth after rubbing the surface of the fabric a certain number of times with dry or wet white cotton cloth, and then rate it with the gray sample card for staining assessment.

Common standards for color fastness to rubbing include GB/T 3920-2008, AATCC 8-2007, AATCC 116-2010 and JIS L 0849-2004. The classification of color fastness to rubbing is based on the degree of staining of white cotton cloth after rubbing:

These standards divide color fastness to rubbing into 9 levels from 1 to 5:

• Level 5: Best. After rubbing, there is almost no color staining on the white cotton cloth, indicating that the sample's color fastness to rubbing is very good.
• Level 4: Good. There is slight color staining on the white cotton cloth, but it does not affect the overall appearance.
• Level 3: Average. There is obvious color staining on the white cotton cloth, but the color distribution is relatively uniform.
• Level 2: Poor. There is obvious color staining on the white cotton cloth, and the color distribution is uneven, which may affect the overall appearance of the sample.
• Level 1: Worst. There is serious color staining on the white cotton cloth, and the color distribution is extremely uneven, indicating that the sample's color fastness to rubbing is very poor.

However, in the test of color fastness to rubbing, due to irregular weaving or uneven dyeing of the fabric, it is easy to cause inconsistent results after multiple frictions, which is accidental. It is necessary to take multiple measurements to obtain a specific report with a high repeatability result.
