Test and rating method of color fastness to washing machine 1

The technical engineer said that the color change assessment and the staining assessment are usually carried out by using the discoloration gray card and the stained gray card. 


Color change evaluation: The color change of the sample can be directly evaluated by using the discoloration gray card with reference to the rating procedure 


1. In order to increase the accuracy of the rating, several people can jointly evaluate. 

Level 5.0: Can be ignored or not stained. 

Level 4.5: The color change is equivalent to Level 4-5 of the color-changing gray card. 

Level 4.0: The color change is equivalent to Level 4 of the color-changing gray card. 

Level 3.5: The color change is equivalent to Level 3-4 of the color-changing gray card. 

Level 3.0: The color change is equivalent to Level 3 of the color-changing gray card. 

Level 2.5: The color change is equivalent to Level 2-3 of the color-changing gray card. 

Level 2.0: The color change is equivalent to Level 2 of the color-changing gray card. 

Level 1.5: The color change is equivalent to Level 1-2 of the color-changing gray card. 

Level 1.0: The color change is equivalent to Level 1 of the color-changing gray card. 

In addition, the color change can also be measured using a colorimeter. 


Staining assessment: The staining of the multi-fiber cloth can be assessed by using the stained gray card and the stained color card. The report should indicate whether the stained gray card or the stained color card is used. 

Level 5.0: Can be ignored or not stained. 

Level 4.5: The color staining is equivalent to level 4-5 of the stained gray card or level 4.5 of the 9-level AATCC stained color card. 

Level 4.0: The color staining is equivalent to level 4-5 of the stained gray card or level 4.0 of the 9-level AATCC stained color card. 

Level 3.5: The color staining is equivalent to level 3-4 of the stained gray card or level 3.5 of the 9-level AATCC stained color card. 

Level 3.0: The color staining is equivalent to level 3 of the stained gray card or level 3.0 of the 9-level AATCC stained color card. 

Level 2.5: The color staining is equivalent to level 2-3 of the stained gray card or level 2.5 of the 9-level AATCC stained color card. 

Level 2.0: The color staining is equivalent to level 2 of the stained gray card or level 2.0 of the 9-level AATCC stained color card. 

Level 1.5: The color staining is equivalent to level 1-2 of the stained gray card or level 1.5 of the 9-level AATCC stained color card. 


The procedure of color transfer from the sample to multifiber cloth or bleached cotton cloth can be determined by comparison with unwashed multifiber cloth or bleached cloth. If multifiber cloth NO.10A or FAA is used, the width of the multifiber strip The aperture is wider than that of the colorimeter, so the staining of this multi-fiber cloth can be measured by the tester.
