Leather rubbing color fastness meter

Leather rubbing color fastness tester is used to test the dyed upper, lining leather, after rubbing the damage and decolorization degree, divided into dry temperature two rubbing methods. Under the specified pressure, with the specified wool felt on a surface of the leather for reciprocal friction test, test the specified number of times, with gray sample card on the surface of the wool felt, leather surface color change for comparison, determine the grade, and record any visible changes or damage to the leather surface.


　　Main uses.

　　Leather rubbing color fastness meter is used to test all kinds of leather resistance to dry and wet rubbing color fastness performance, widely used in the leather industry, factory production direct sales, high cost performance, quality assurance.
