Understanding A Fogging Test Chamber

       Fogging Test Chamber  ,To determine the fogging characteristics of automotive interior trim of textiles, plastic or leather. Fogging is the residue deposited on interior glass of chemicals released from materials under specific temperature conditions. 


     The sample is heated in the fogging tester fog cup and begins to evaporate, and the volatilized gas is condensed on a glass or aluminum foil that has been cooled by the cooling chamber.


     After the completion of the condensation process, the glass plate or aluminum foil was removed. Atomization and volatilization characteristics of the sample were obtained by measuring the atomization value or weight of the condensing component of the glass plate or aluminum foil and compared with the data before being condensed.

      Gloss method:The sample is condensed in the fog cup by the vaporized gas condensed on the low temperature glass plate. The gloss value of the sample can be obtained by comparing and calculating the gloss value before and after the condensation of the glass plate.

     Haze method:The sample was condensed in the fog cup by the vaporized gas condensed on the low temperature glass plate, and the haze value of the sample was obtained by comparing and calculating the haze value before and after the condensation of the glass plate. (Optional)


 Weight method:The sample is heated in the fog cup by the vaporized gas condensed on the low temperature aluminum foil, and the weight of the sample atomization-coagulation can be obtained by weighing the weight of the aluminum foil before and after condensation.

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...

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...

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 ...
