Color fastness to rubbing (wet condition)

Objective

This test is used to check whether repeated rubbing is able to cause deterioration of the leather colour, on the one hand, and whether the colour can run (transfer) onto the backing material.

Principle

The test consists in subjecting a 100 x 25 mm specimen to rubbing (to-and-fro) under constant pressure, with a wet standardised felt pad. The deterioration and staining are then evaluated against greyscale.
