Color Fastness Test to Water ( ISO 105 EO1)

Theory:
Color fastness to water is designed to measure the resistance to water of dyed, printed, or otherwise colored textile yarns and fabrics.The test method by which this test is carried out is AATCC 107-1991 or ISO 105 E01. This method is to assess the degree of cross staining which may occur when garments are left in contact when damp. The test measures the resistance to water of any colored textiles. 

Color fastness to 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:
Distilled water or de-ionized water is used in this test method because natural (tap) water is variable in composition.

Sample Preparation:
Cut the specimen & multi-fibre at 10×4cm & sewn together. This is the composite test sample.

Working Procedure:

Wet in distilled water at room temperature & it will suck water.

Place it in acrylic resin plates & put the weight on to the plates.

Keep it in oven & keep the temperature at 37± 2°C for 4hrs.

Open the specimen & dry it in the air hot exceeding 60°C.

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