Test Methods for Circular Locus Pilling Test Machine

The common test methods for deciding the piling performance of fabric are chamber piling method, martindale piling method, the elastic pad method, circular locus piling method and random tumble type piling method and so on. Each test method varies due to the difference of fabric materials, usages and product export places.The main methods used in each region are classified as follows:

 Martindale piling method - European market
Chamber piling method - European market
Random tumble type piling method - American market, including Japan and Canada
Circular locus piling method - Chinese market

 The wide range of the applicability of circular locus pilling method is the most common test method used in our country. Its corresponding Chinese standard is GB/T  4802.2. The instrument used in this method is cheap, simple in structure and easy to operate with relatively high recognition by its clients.
The basic test principle of Circular Locus Piling Test Machine:  in accordance with the specified method and the set test parameters, the fabric sample under certain pressure along with the circular locus starts abrasion with nylon brush for piling , and then rubs against  the fabric abrasive, or directly abrades with the abrasive for piling. Then, the sample will be taken down to compare with corresponding sample under the stipulated lighting condition for visual assessment of the sample's piling property. The rating is rated from grade1 to 5. Grade 5 is good, grade 1 is the worst, and half grade rating is allowed.

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 ...

what is the Working Principle of fogging tester?

Fogging Test Chamber   is the best tool to determine the fogging characteristics of automotive or other vehicle interior materials. The fogging tester is applicable for gravimetric method, photometric method and haze measurement method. Working Principle: The main frame of the Fogging tester includes a water sink fully filled with specified ethylene glycol, which can reach a high temperature. At the time of testing, leather specimens are put in the six standard glass containers filled with  high temperature liquid, and the stainless steel containers are placed above each glass. Relying on the constant water flow distribution, the temperature can maintain at 20℃ constantly, and it can be adjusted through the regulation device connected to the main frame. This controlled environment condition will generate a layer of “fog” on the surface of specimens. The operator can determine the fogging characteristics of materials based on gravimetric analysis method or refraction...

The Scratch Tester Working Principle From Qinsun LAB

The scratch test machine is used to evaluate the shear, scratch, planing, scraping and engraving performance of the material. Its applications include rigid organic materials, plastics and glass, and so on. The test parameters, such as the speed of scratches, the length of scratches, the distance between scratches and the number of lines, are the test equipment with strong applicability and convenience. scratch tester Working principle: Coating has three aspects: the action of protection, decoration, and hide the defects of products, and the three main hardness has a lot to do with paint, paint film hardness is said film one of the important properties of mechanical strength, is an important indicator of measuring coating product quality, and measure the coating hardness is an important index of the scratch resistance of determination; Coating good product in the process of packaging, transport and use will draw by hard brush, not row brush the paint film is often leave scratc...
