Product Overview / Description
Color-deepening Agent is a high-performance functional auxiliary designed for the post-dyeing treatment of textiles. Through a special chemical mechanism, it significantly enhances the color depth and vibrancy of dyed fabrics, improves color fastness, and delivers fuller, more uniform shades. The result is a visibly upgraded appearance and higher commercial value for finished textile products.
This product effectively deepens the color of dyed fabrics — especially black, navy blue, and dark shades — while maintaining the original hand feel. It is suitable for use after dyeing with reactive dyes, sulfur dyes, disperse dyes, and direct dyes, and is compatible with a wide range of fiber types including cotton, polyester, nylon, and their blends.
Key Features & Benefits
-
Significant color deepening effect: Markedly increases color depth on dark and medium-dark shades, particularly black, navy blue, and deep-toned fabrics
-
Improved color vividness: Enhances brightness and saturation for a fuller, richer appearance
-
Enhanced color fastness: Contributes to better rubbing fastness and wash fastness after finishing
-
Dye savings: Reduces dye consumption, helping lower production costs while achieving target shade depth
-
Broad compatibility: Suitable for cotton, polyester, nylon, and blended fabrics; compatible with reactive, sulfur, disperse, and direct dye systems
-
Easy application: Can be applied by padding or exhaust processes under standard finishing conditions
Composition
Specialty modified silicone / polymer emulsion system.
Application
Color-deepening Agent is applied as a post-dyeing finishing treatment on dyed fabrics. It is suitable for exhaust and padding processes and can be used on a wide range of textile substrates.
Recommended for:
-
Cotton, polyester, nylon, and their blends
-
Fabrics dyed with reactive, sulfur, disperse, and direct dyes
-
Black, navy blue, and other dark shades requiring depth enhancement
Typical Physical Properties
| Property | Typical Value |
|---|---|
| Appearance | Milky white liquid |
| Ionicity | Weak cationic |
| pH (1% aqueous solution) | 6 – 7 |
| Solid content | 19% – 21% (105°C, 3h) |
Application Method
| Application Method | Dosage |
