Carpet Abrasion Tester For Testing Lab Workshop.
Carpet Abrasion Tester - For Testing Lab
Abrasion resistance is the most important property on which the
durability of a carpet depends. Abrasion resistance of carpets is
determined by abrading a circular test specimen against a specified
abradant for various number of rubs and determining loss in mass versus
number of rubs, or the number of rubs required to reveal the backing.
The Carpet Abrasion Tester consists
of two vertical shafts rotating in the same direction at same speed
with their centers offset. The specimen of carpet is clamped on the
lower shaft and is rubbed against a larger circle of standard crossbred
fabric clamped on the bottom of the upper shaft.
The rotations of
the shafts are such as to give a constant relative velocity between
specimen and abradant at all parts of the specimen. A counter is
provided to record the number of rubs, with arrangement to stop the
machine automatically after preset number of rubs. Means for applying a
constant pressure by loading the upper shaft on the test specimen are
also provided.
