Gakushin Color Fastness Tester Is Suitable For Dry And Wet Rubbing Tests

2022-03-30

Rubbing color fastness is one of the important characteristics for good apparels. 

Rubbing color fastness refers to ability to sustain original color of dyed fabrics when rubbing. 

Dry rubbing color fastness refers to the situation of fading and staining of dyed fabric when rubbed with standard white cloth. 

Wet rubbing color fastness refers to the situation of fading and staining of dyed fabric when rubbed with standard white cloth which water content is 95% to 105%. 


The evaluation of Rubbing color fastness depends on the degree of staining of white cloth. After testing, the white cloth is compared to staining sample cards to measure staining fastness. Rubbing color fastness, same as washing color fastness, divide into 5 grades and 9 files, among which grade 5 is the best and grade 1 is the worst. The friction fading of fabric is to make dye fall off caused by friction. Wet rubbing is influenced by both external force and water, so it is about one level lower than dry rubbing.
