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.
