A lower ΔE value indicates better anti-staining performance.
Test Method:
-
Fabric: Standard white cotton
-
Color fixative dosage: 0.2%
-
Reactive black dye concentration: 0.05%
-
Bath ratio: 1:50
-
Soaping condition: 60 °C × 30 minutes
These results demonstrate the product’s excellent ability to disperse active dyes and prevent dye redeposition on fabric during soaping.
