2. What Is Washing Fastness Test

The washing color fastness test is used to test the washing color fastness, dry washing color fastness, rinsing color fastness, washing powder performance, and other washing and dry cleaning fastness properties of various textiles. Anyways, most of the textile products would be washed. In this process, color fastness to washing is of great importance. High resistance of color fastness to washing can not only ensure that the clothes will not fade during the washing process, but also prevent the clothes from staining other items. At the same time, it can also ensure that the washing process does not cause harm to humans and the natural environment.

4. Measurement of Washing Fastness / Test Procedure

  • Make the sample in contact with adjacent fabric;
  • Launder the sample inside of the cup with a specific ratio test solution, steel ball, temperature;
  • Run the wash fastness tester at certain speed and for a certain period of time;
  • Extract the excess water from the sample;
  • Dry the sample under certain condition;
  • Evaluate sample color change and adjacent fabric staining with gray scales;

*above test procedure is referred from colour fastness to washing iso 105 c06

* Unuo Instruments supplies multifibre adjacent fabric(ISO 105-F10), two single-fibre adjacent fabrics(ISO 105-F01-F07), gray scales for sale.

5. Color Fastness to Washing Rating

The color fastness can be divided into 2 parts: sample color change & adjacent fabric color staining. For the evaluation, you may need color matching chamber. There are 5 grade for color change and staining as below.
