Martindale Abrasion & Pilling Testing Equipment provides a means of determination of the abrasion as well as
pilling resistance of all knitted, woven, non-woven, non-woven and
coated fabrics.
1. FOR ABRASION
The equipment is designed to subject specimens under test to a
controlled amount of rubbing at comparatively lows pressures and in
continuously changing directions to ensure that all surface fibers
on the specimens are flexed in order to compare 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 in determined by the number of rubs to breakdown or by the
loss in the mass of specimens.
Up to 4 specimens are tested simultaneously. Each one is prepared
and mounted separately in a Specimen Holder. To improve even wear,
specimen lighter than 500g/m2, are backed with a standard
Polyurethane foam. The Abradant material (Standard Felt &
Abradant Fabric), against which the specimen is rubbed, is clamped
tightly over the abrading Plateform to prevent possible
metal-to-metal contact.
The Path traced by the test specimens 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 insure that the surface fibres of the specimens
are fixed in every direction.
2. FOR PILLING
The method of testing for pilling is suitable for knitted and woven
fabrics, made from Staple spun yarn.
The stroke of the top plate is reduced from 60.5 to 24 mm. The area
of the exposed Specimen is 64 cm2, the holders esurts a pressure of
2.5 CN/cm2 (Knitted).
Using the Lissajous motion, three pairs of the specimens are rubbed
against each other for 125,500 and 2000 revolution respectively.
The test takes about 40 minutes the degree of pilling is assessed
against photographic standard.
