Rub Proofness Tester For Testing Lab Workshop.
Rub Proofness Tester - For Testing Lab
The Rub Proofness Tester is used for testing the fastness of
colour of light leathers to wet and dry rubbing and measuring the
transfer of colour to the material with which it is rubbed. The test
piece is rubbed with a rotating circular felt pad pressed against it
under the specified load, and the number of revolutions of the pad
required to produce certain effects is measured.
This
equipment can also be used to assess the degree of damage to a material
during mild wet abrasion to imitate the scuffing action of a damp hose
on footwear insole during wear. A rotating wet circular felt pad,
covered with a worsted repp fabric, rubs the test specimen under a
specified contact force. The overall damage to the test specimens is
assessed by measuring their mass loss after a specified numbers of
revolutions. Civil lab equipments manufacturers
