“VESLIC” RUB FASTNESS TESTER

ITEM 30A

APPLIANCE FOR TESTING THE COLOUR FASTNESS TO THE WIPING (FASTNESS TO LEATHER PROCESSING AND UTILIZATION).

Veslic testing machine for leathers determines dry and wet colour fastness resistance to cycles provided by rubbing.
Therefore this equipment evaluates the behaviour of the skin/leather surface to rubbing with a wool felt pad.
During the test the felt (dry or wet) becomes more or less coloured, it depends on the amount of colour on the surface of the leather (finishes, pigments, dyestuff and buffing dust). In this operation the surface and the color of the skin can also change (may be alterated).
The colour fastness resistance is evaluated using the Grey Scale.
This equipment features n°4 felt carrier stations capable of working with 500 gr or 1 Kg applied weight.
Automatic cycle counter allows self-repeating motions up to 9.999 rounds.
The Veslic is available in the 1 working place, and 4 working places versions in order to test several samples simultaneously.
