Evaluating Comfort Using Qinsun Sweating Guarded Hotplate

The sweating guarded hot plate instrument, simulating the heat and moisture transfer from the body surface through clothing material to the environment, was designed for the measurement of thermal resistance and water vapor permeability of fabrics, relating to comfort characteristics of the garment. A number of factors govern the accuracy of the measurement, namely air velocity, leading edge effect, bubbles and wrinkles, membrane effect and so forth. The sweating guarded hot plate apparatus provides reproducible and repeatable results.

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...
