Product type
High energy disperse dyes are a class of synthetic dyes primarily used for coloring polyester and other synthetic fibers. These dyes are characterized by their ability to disperse in water, allowing them to penetrate the fibers effectively during the dyeing process. They are typically made from complex organic compounds that provide vibrant colors and excellent lightfastness.
| Chemical structure | Azo, anthraquinone, or other organic compounds |
| Solubility | Dispersible in water at high temperatures |
| Application method | Dyeing at temperatures typically between 130°C to 140°C |
| Color range | Wide range of colors available |
| Lightfastness | Good to excellent, depending on the specific dye |
When selecting high energy disperse dyes, consider the specific fiber type and the desired colorfastness. It's essential to specify the application method, as dyeing conditions can vary significantly. Additionally, inquire about the dye's lightfastness ratings and any relevant certifications for safety and environmental compliance. Quantities can vary based on production needs, so be clear about your requirements when requesting a quote.
