Color fastness to washing procedure ( ISO 105 C06 )
Color fatness to washing refers to the process of mechanically agitating a textile specimen in a soap solution for a predetermined amount of time and temperature while it is in touch with one or two designated adjacent materials. The specimen is subsequently washed and dried. Data color
Preparation of wash liquor:
- Dissolving the detergent:
- Weight 4g of ECE Reference Detergent to at least 2 decimal places.
- The detergent may be dissolved in app 300 ml grade 3 water by : Heating solution or Addition of hot water.
- Then cool by adding cold water and make up to; 1000 ML FOR TEST A & B or 950 ml for test C , D & E .
- Don’t add solution at temperature 40c to volumetric flasks .
2. Addition of perborate ( for A2S, B2S, C2S, D2S & E2S)
- Add 1g of sodium perborate
- Prepare test solution by heating the liquor to a max 60c .
- The solutions must be used within 30min of preparation .
- Excess must be discarded.
