Qinsun instrument provides you with high quality Martindale Abrasion Pilling Tester which is calibrated and available at affordable price.It consists of four testing plates on which the abrading fabrics is attached, these four testing table are mounted on the base plate of the instrument. There is revolving plate, which revolves with the help of three cranks, pegs & motor.There are four sleeves attached on the revolving plate. The sample holders for abrasion & pilling testing are provided with the instrument. There is a set of weights for proper pressure on the test specimens. Templates for cutting the samples & abrading cloth and their mallet are also supplied as standard accessory.
Testing Principle Of Martindale Abrasion Tester:
Circle samples are grazed by fabrics with compatible material considering the recommended pressure in the trajectory of Lissajous movement, to accomplish certain turns and calculate the tested samples degree of pilling.The Abrasion of the fabric can be tested through two methods.Inspect the specimens without removing them from the holders at regular intervals and note the number of rubs when at least two threads are broken.This should be assessed independently for each specimen and the specimens removed when they reach end point.
Abrade two specimens to end points as in above case and then abrade further pairs of specimens.Weight all the specimens before and after abrasion and plot a graph of weight loss against the number of rubs.Draw a line through the points and determine the rate of weight loss in mg per 1000 rubs if reasonably linear.The degree of pill formation can be visually assessed by the set of photographic rating standards available for comparing the tested specimen.
This Martindale Abrasion Test apparatus gives a controlled amount of abrasion between fabric surfaces.Abrasion is given at comparatively low pressures in continuously changing directions.In this test, circular specimens are abraded under known pressure.This abrasion is given by a motion that is the resultant of two simple harmonic motions at right angles to one another.The fabric is abraded against a standard fabric called abradant.Abrasion resistance is estimated by visual appearance or by loss in mass of the specimen.
