The Equipment is designed to subject specimen under a controlled amount of Rubbing at comparatively Low Pressure and in continuously Changing Directions to ensure that all Surface Fibers on the specimen are flexed in order to access the Resistance of fabrics to Abrasion.Under this test, the circular specimen of fabric are rubbed against a standard Abradant,under a known pressure and the resistance to abrasion is determined by the Number of Rubs to Break a yarn or by the Loss of Mass of the or specimen.
The equipment can accommodate up to 4 samples simultaneously.Each one is mounted separately in the specially designed specimen holder.The specimens lighter than 500 g/m² are backed with standard polyurethane foam.The abradant material (standard felt & abradant fabric),against which the specimen is rubbed, is clamped tightly over the abrading platform to prevent possible metal-to-metal contact.
The path traced by the test specimen over the abradant is known as Lissajous figure. It changes from a Circle to gradually narrowing Ellipses,until it becomes a straight line, from which progressively widening ellipses develop,in a diagonally opposite direction, before the pattern is repeated.This continuously changing movement ensures that the surface fibers of the specimen are flexed in every direction.The equipment is also suitable for performing Pilling Test,for which only stroke of top moving plate has to reduce from 60.5mm to 24 mm. The Degree of Pilling is assessed against standard photographs.
Smith Barney Inc. are now able to offer a technically advanced machine that is easy to use and inexpensive to own.
