Product type
Anthraquinone vat dyes are a class of synthetic dyes derived from anthraquinone compounds, known for their vibrant colors and excellent lightfastness. These dyes are typically used in the textile industry to dye cotton, wool, and other fibers, providing deep and rich hues that are resistant to fading. The dyeing process involves a reduction step that transforms the dye into a soluble form, allowing it to penetrate the fibers before being oxidized back to its insoluble form, which locks the color in place.
| Chemical structure | Derived from anthraquinone |
| Color range | Wide range including blue, green, and red shades |
| Lightfastness | Excellent lightfastness ratings |
| Water resistance | Good water resistance properties |
| Application method | Requires reduction and oxidation processes |
When selecting anthraquinone vat dyes, consider the specific color requirements and the type of fibers you will be dyeing. It's important to specify the desired lightfastness and water resistance levels, as well as any regulatory compliance needed for your application. Additionally, inquire about the dye's solubility and the necessary reduction agents for the dyeing process. Quantities may vary based on production needs, so be clear about your order volume.
