Indigo Blue Features:

1. Chemical composition: Natural or synthetic reducing dyes (extracted from plants by ancient methods, mostly synthetic in modern times).
2. Color: Classic blue, can be overlaid and dyed to form light and dark layers (such as the “snowflake” effect of denim).
3. Fastness:
-Poor wash fastness, deliberately pursuing fading effect (such as jeans being worn out).
-Moderate light fastness, but gradually fades to form a unique appearance.
-Low friction fastness and easy transfer (white shoes dyed blue is a typical problem).

Indigo Blue Application:

-Main application: Core dye for denim fabric, with a small amount used for wool and silk.
-Featured craftsmanship: The yarn is dyed multiple times (ring dyeing), with only the outer layer colored to create a “white core” effect.
