The leather rubbing color fastness tester is designed to evaluate the resistance of dyed leather surfaces to color transfer under friction. 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.
It supports both dry and wet rubbing test methods, providing reliable data for assessing leather color fastness performance.
This tester is suitable for testing various dyed leather materials to determine surface color transfer and rubbing durability. It is widely used in leather manufacturing, footwear, luggage, upholstery, automotive interiors, and quality inspection laboratories.
