Working Procedure of Perspiration tester

   Perspiration is on everything we touch or comes in contact with our bodies. It can react with certain materials and trigger allergies or shorten product service life. While the mechanics of perspirations tests have been specified since 1947, there is no consensus for an artificial perspiration mixture that will successfully mimic natural human eccrine perspiration.
 

  Perspiration tester determines colorfastness of textiles to human perspiration. The KFG-2041 Perspiration Tester consists of two stainless steel frames. Each frame be loaded with up to 20 samples of 10 x 4 cm between the supplied acrylic separator plates. Loading weights for AATCC TM 15/106/107 and ISO 105 E01/2/4 are included.


Working Procedure :
  Thoroughly wet one composite sample in a solution of PH8.0 at the liquor ratio of 20:1 and allow it to remain in this solution at room temperature for 30min. pour off the solution and place the composite sample between two glasses plates measuring about 7.5×6.5cm under a force of about 4.5kg.

   Treat the other sample in the same way but with the solution at PH 5.5.
Place the apparatus containing the samples in the oven for 4 hour at 37±2C˚
Separate the sample from the white cloth and dry them apart in air at the temperature not exceeding 60C˚.Assess the change in colour of the specimen and the staining of the white cloth with the greigh scale.

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...

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...
