Fabric Thickness Gauge.
One of the tests for determination of colourfastness of dyed leather is the rubbing test. This test is used for the determination of damage and transfer of surface colour from a material during mild dry or wet abrasion. It is primarily intended for testing of leathers, but may also be used for testing other similar materials such as plastics and textiles. This equipment can also be used for testing abrasion of Insoles.
The Ramp Veslic Rubfastness Tester consists of a rigid flat metallic platform on which the test specimen can be held firmly and a rubbing finger that rubs against it under a specified load. The platform is fixed over the base of the equipment and lies in a horizontal plane. The test specimen is held firmly over the platform with the help of two clamps holding it at both ends.
The specimen-mounting platform is in two parts. The fixed part of the platform is held firmly on the base of the tester, while the movable part can be moved away from the fixed part after the test specimen is mounted over the platform to subject it to an initial extension.
The abrading finger has a flat square shaped cavity in it, in which a square shaped felt piece can be held during the test. The felt piece picks up colour lost by the test specimen during rubbing.
Motion to the finger is given through a reciprocating arm, which runs on two ball-bearings to minimize friction and to apply a uniform load on the finger. The arm is moved by a motor-operated crank and connecting link. A pre-set counter records the number of abrading cycles, as well as switches off the motor after a desired number of rubs.
The equipment is finished in Shore Blue Mettalic painting and bright chrome plating to give it a corrosion resistant finish.
Grey scale for assessing change in colour and grey scale for assessing staining, needed to evaluate the results of the test, are available as optional accessories.
