Print Friendly and PDFPrintPrint Friendly and PDFPDF

Color Fastness to Washing:
Color fatness to washing means, A specimen of the textile, in contact with one or two specified adjacent fabrics, is mechanically agitated under described conditions of time and temperature in a soap solution, then rinsed and dried. The change in color of the specimen and the staining of the adjacent fabric are assessed with the grey scales.

In my personal experience, in case of fastness test color fastness to washing is the first and most important requirements of buyers. There are a number of ISO test for color fastness to washing.
Washed sample
These are :
1. ISO test no-1
2. ISO test no-2
3. ISO test no-3
4. ISO test no-4
5. ISO test no-5
6. ISO 105 C06
  • ISO 105 C06 A2S
  • ISO 105 C06 B2S
  • ISO 105 C06 C2S
Among them ISO 105 C06 is the first choice of maximum buyers.
Now I will discuss about those fastness test.
