In daily life, leather products, such as leather clothing, purses, leather shoes, etc., produce friction with their own or human body and lead to color fading.

Standards

ISO 11640Leather -- Tests for colour fastness -- Colour fastness to cycles of to-and-fro rubbing.

SATRA PM 173 Reference standard of footwear testing content and methods.

QB/T 2537-2001 Leather -- Tests for colour fastness --Colour fastness to reciprocating rubbing.

DIN 4843Safety Footwear; Safety Requirements, Testing QB/T 2226 Shoelace wear test method, light industry standards.

GB/T 20991-7.3 Personal protective footwear test method.

Consumables

Friction material: White wool felt, size 15mm × 15mm.

The punched pure wool felt piece should meet the following requirements: pH of water extract between 5.5 ~ 7.0; mass per unit area (1750 ± 100) g / m2 - thickness (5.5 ± 0.5) mm.

Technical Parameters

1 - Test bench: a horizontal metal platform; a holder for fastening the leather to the platform, leaving approximately 80mm exposed; a device with which the leather may be extended 10% to 20% linearly in the direction of rubbing (sample size 120mm × 20mm).

2 - Test column: weight (500 ± 25) g.

It can be moved, but also firmly fixed.

including: A) Test head area: 15mm × 15mm; B) Device for adjusting the test head to bring the felt pad into horizontal contact with the test platform; C) Load bearing blocks: (500 ± 10) g.

After loading, the total mass of the test column is 1000g; D) Adjustment device: adjust the test column up and down so that the test head makes horizontal contact with sample.

3 - Device that drives test bench for reciprocating motion: test head makes forward-backward motion with a stroke of 35mm ~ 40mm at a frequency of (40 ± 2) cycles / min.

4 - Counter: LCD digital display, round-trip as one time, the number of cycles can be set to 5 to 500 times.

5 - Device that can adjust the test column in the horizontal direction (optional): the test head can be rubbed against the leather samples at 2 to 3 different angles.
