When buying clothes or textile backpacks, have you ever done such an action, that is, rubbing the fabric with the clothes on your body to confirm the color fastness of the fabric? I'm not afraid of your jokes, I really did this.
So why do we pay attention to the fabric colorfastness, and what method is used to test the color fastness of textiles?
I am going to tell you this kind of machine which is called Textile Testing Equipment Fabric Colorfastness Crock Meter for AATCC Test Method.
One of the testing for determination of color fastness of dyed or printed textiles or leather is the crocking test. This test is used for the determination of color fastness against rubbing, either under dry or under wet conditions. In this test and moving brass finger of specified shape and size rubs against the test specimens under test and the amount of color transferred to a piece of abradant fabric fixed over the base of the moving finger are graded with the help of standard grey scales to evaluate the color fastness against rubbing.
