Color Fastness to Sea Water (ISO 105 E02)

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.

Color Fastness to Sea Water
Apparatus:
  1. Perspiration Tester
  2. Oven
  3. Multi fiber fabric
  4. Grey scale
  5. Color matching cabinet
  6. Glass plate or Acrylic resin plates
  7. Weight 12.5 kPa or 5kg pressure
  8. Glass beaker
  9. Stirring rod
Reagent:
  1. Distilled water or de-ionized water
  2. 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:

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. 

Change in color is assessed with the help of Grey Scale.
