How Does Martindale Abrasion Tester Work?

          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.

Classfication Of The Textile Testing

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Many textile tests have many types. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It's basically an enclosed box. Textiles...

Standard Procedure Of Oxygen Index Test Methods

Oxygen index tester test methods, which describes the tendency of a material to sustain a flame, are widely used as a tool to investigate the flammability of polymers. They provide a convenient, reproducible, means of determining a numerical measure of flammability. A further attraction is that the test method uses inexpensive equipment and only requires a small sample size. These methods have been used to systematical investigate the relative flammabilities of fire-retarded materials, frequently comparing the effectiveness of fire-retardants and fire-retardancy mechanisms. The quintessential feature of oxygen-index methods is that the sample is burnt within a controlled atmosphere. The standard procedure is to ignite the top of the sample, using a gas flame which is withdrawn once ignition has occurred, and to find the lowest oxygen concentration in an upward flowing mixture of nitrogen and oxygen which just supports sustained burning. The criticality criterion typically tak...

How To Process The Elmendorf Tear Strength Test

The Elmendorf tear tester has been developed specially for the paper industry and is outstanding for simplicity of operation and high measurement accuracy. The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted, and, after the measurement, results and statistics can be  displayed.Each pendulum is supplied with the appropriate control weight so that, with the help of the service program, it can easily be checked for functionality and balance. The Elmendorf tear test Procedure:     Cotton fabric was taken.     Warp and weft direction of the fabric was identified.     Two strips were cut from the fabric in both directions having dimensions of 100 x 63.5 mm.     The sample was then fixed in the jaws of the ...
