Theory:
The
test method by which this test is carried out is ISO 105 E02. This test in
intended to determine the resistance of the color of dyed textiles to immersion
in sea water.

Apparatus:
- Perspiration Tester
- Oven
- Multi fiber fabric
- Grey scale
- Color matching cabinet
- Glass plate or Acrylic resin plates
- Weight 12.5 kPa or 5kg pressure
- Glass beaker
- Stirring rod
Reagent:
- Distilled water or de-ionized water
- NaCl (30 gm per liter)
Sample
Preparation:
Cut the specimen & multi-fibre at 10×4cm & sewn together. This is the composite test sample.
Working Procedure:
Cut the specimen & multi-fibre at 10×4cm & sewn together. This is the composite test sample.
Working Procedure:
Immerse
each composite specimen in a separate container of the test solution at room
temperature
↓
Agitate the test specimen to ensure through wet out
↓
Remove the test specimen from the test solution
↓
Lay the test specimen between two acrylic or glass plates and set in the perspiration tester
↓
Adjust the perspiration tester to produce a pressure of 12.5 kPa on the test specimen
↓
Place the tester into an oven and set the temperature of 37±2 0C for 4 hours
↓
Remove the perspiration tester from the woven
↓
Open out the test specimen (by breaking the stitching on all side except one of the sorter sides, if necessary) and dry the specimen in an incubator (oven) not exceeding 60 0C.
