Product type
Reactive dyes are a type of dye that chemically bond with the fibers of textiles, providing vibrant colors and excellent wash fastness. They are typically made from organic compounds that contain reactive groups, allowing them to form covalent bonds with the hydroxyl or amino groups in the fiber structure. This unique bonding mechanism results in dyes that are highly resistant to fading and washing out, making them ideal for use in various textile applications.
| Chemical composition | Organic compounds with reactive functional groups |
| Color range | Vibrant shades across the color spectrum |
| Application method | Batch dyeing, continuous dyeing, and printing |
| Fiber compatibility | Cotton, wool, silk, and some synthetic fibers |
| Fastness properties | Excellent wash and light fastness |
When selecting reactive dyes, consider the type of fiber you will be dyeing, as compatibility varies. Specify the desired color shades and fastness requirements to ensure optimal performance. Additionally, inquire about the dye's environmental certifications and compliance with industry standards. Quantities may vary depending on production scale, so be clear about your needs when requesting a quote.
