Product use: In the production of leather sofa, check the color fastness of the sample when choosing leather to ensure that the material will not be complained of due to fading. Using a small piece of wool blanket (15X15 mm), under a certain pressure, a certain period of repeated friction on the side of the sample leather, using a gray scale card to check the color change of the wool felt, and record all visual changes and damage.
