Two Test Modes: Dry & Wet: Versatile testing for various
conditions.
Horizontal Metal Platform: Ensures consistent friction during
tests.
Weight Block: Precise 500g ± 10g for accurate measurements.
Motion Speed: 40 ± 2 times/min for standardized testing speed.
The leather rubbing color fastness tester is designed to evaluate
the resistance of dyed leather surfaces to color transfer under
friction.
It supports both dry and wet rubbing test methods, providing
reliable data for assessing leather color fastness performance.
The machine applies a specified pressure and uses a special wool
felt rubbing head to perform reciprocating rubbing movements on the
leather surface for a defined number of cycles.
