Discussion of color fastness to rubbing

Author:QINSUN Released in:2023-07 Click:102

Scrub fastness refers to the resistance of the color of textiles to abrasion or staining on other textiles and is one of the most important indices of textile color fastness , i.e. the grade the fading of dyed fabric after rubbing, which can be divided into dry and wet rubbing. The rub fastness in particular plays an important role. The assessment is divided into 5 levels (fastness number), where 5 means very high rubbing fastness and level 1 means very low.

As a professional testing organization or professional inspector, color fastness to rubbing is so important; we should have a deeper understanding of the color fastness to rubbing test so that our test results are close to the true value of the sample.
