How The Martindale Test Goes On

The Martindale test involves rubbing a piece of worsted wool cloth in a circular motion on a flat mounted fabric sample. Each pass is one cycle, and the number of cycles the test fabric can withstand before showing a change in appearance (such as thread breakage or pilling) is its abrasion rating. At the beginning of the test checks are made every 1,000 cycles, and if no wear is apparent, the fabric is put through another 1,000 rub cycle. As the test goes on, sometimes these intervals will increase.

How does the Martindale test work?
The fabric being tested is pulled taut and loaded onto the lower plates of the Martindale machine. Small discs of worsted wool or wire mesh (the abradant) are continually rubbed against the test specimens in a Lissajous figure – a wandering, oscillating circle. The fabric is continually inspected for wear and tear, and the test ends when two yarns break or when there is a noticeable change in appearance.

How can you read a Martindale test result?
Test results are given as a score of 1000’s of rubs or cycles, and the higher the number is, the more suitable the fabric is for heavier useage. Fabrics are categorised depending on their test results.

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...

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 ...

Synthetic Blood Penetration Tester for Medical Face Mask

Features of Synthetic Blood Penetration Tester: 1. Mask fixture is metal human head mold, which can fully simulate the actual use state of the mask. 2. Metal human head mold can be rotated at a certain angle, which is convenient for sample clamping. 3. Specially designed injection control device, a certain volume of synthetic blood can be sprayed in the controlled time. 4. Instrument uses a gas source that can provide (700±25) kPa stable air pressure. 5. It can simulate the liquid injection velocity corresponding to the human blood pressure 10.6 kPa、16.0kPa 、21.3kPa (i.e .80 mmHg、120mmHg、160mmHg) for the test. 6. A fixed target plate is provided to block the high pressure edge part of the ejected liquid flow, only the steady flow part is sprayed on the area sample, which increases the accuracy and repeatability of the test. 7. This blood penetration testing equipment uses imported special aluminum wire drawing panel, equipped with metal keys, sensitive operation, not easy to dama...
