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 ...

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...

Comparative analysis of water-cooled and air-cooled xenon lamp aging tester

Xenon lamp aging test chamber is the core component of using the box full sunlight spectrum xenon lamp tube simulation, under different environmental conditions to simulate the material aging law, through the experimental results to evaluate weather resistance of materials and products. This paper focuses on the comparative analysis of the advantages and characteristics of the water-cooled and air-cooled xenon lamp aging testing machine. Air-cooled xenon lamp aging test machine : A circular wind is used to cool the heat-trapping xenon lamp tube. Air-cooled xenon lamp tubes used in air-cooled xenon lamp aging test box, generally a typhoon cold xenon lamp aging test chamber is equipped with three air-cooled xenon lamp tubes, and table 1 air-cooled xenon lamp weather-resistant chamber equipped with xenon lamp tubes. The power of the air-cooled xenon lamp tube is generally 1.8kw, and the length of the lamp tube is 340mm compared with that of the water-cooled xenon lamp. The diameter of...
