Abrasion resistance test method and requirements

abrasion resistance is one of the important performance of denim clothing, but also the production enterprises and consumers are mainly concerned about the indicators. Poor wear resistance of clothing, easy to wear after wearing, affecting the use of the product cycle.
At present, FZ / T81006-2007 "denim clothing" standard for the detection of wear resistance is mainly used GB / T 21196.2-2007 "Textile Martindale fabric abrasion resistance of the second part: the determination of sample damage" The principle is to cut a representative sample on the denim clothing, placed on the Martindale wear tester, in the specified load and speed, the trajectory for the Lissajous (Lissajous) graphics plane motion and abrasive Friction, the specimen holder can be free to rotate about the center axis perpendicular to the horizontal plane.
Two or more non-adjacent yarns were completely broken, the test was terminated, and the abrasion resistance of the fabric was determined according to the total number of times the sample was worn. In the daily testing process, FZ / T 81006-2007 "denim clothing" on the denim wear resistance made a clear request, the nominal pressure of 9kPa, denim fabric unit area quality in 339g / m2 above, wear resistance requirements ≥ 25000 times , The unit area of ​​the quality of 339g / m2 below, wear resistance requirements ≥ 15000 times.

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 ...

Correct Use Of Color Assessment Cabinet

Observation Angle: The following points are all the facilities required for the Color Assessment Cabinet , and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are: A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees. B, light source and 45 ° inclined channel 45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical). The location of the 45 ° light samples: Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing...

3 main functional values of the Burning Manikin System

3 main functional values of the Burning Manikin System 1) Research on the heat transfer mechanism of individual soldier's flame retardant equipment By simulating the battlefield fire conditions of different intensities, the changes of human skin surface heat flow and skin temperature by burning dummies, a good human body-clothing-fire environment conditions are created, and the individual soldiers are flame retardant The study of equipment heat transfer mechanism provides an important research method. 2) Research and screening of flame retardant fabrics for individual soldier equipment Quantitatively test the flame retardant properties of different individual soldier equipment fabrics through the burning dummy system, guide the research on flame retardant fabrics, and screen out flame retardant fabrics with excellent performance. 3) Structure and style design of individual soldier's flame retardant protective equipment The structure and style of individual soldier's flame r...
