Procion Red MX 8B

Description:

Procion Red MX 8B, with the CAS number 57583-69-4, is a synthetic dye belonging to the class of reactive dyes, specifically designed for dyeing cellulose fibers such as cotton. This dye is characterized by its vibrant red color and excellent lightfastness, making it suitable for various textile applications. Procion Red MX 8B exhibits high reactivity due to the presence of reactive groups that form covalent bonds with the hydroxyl groups in cellulose, ensuring strong adherence to the fabric. It is water-soluble, allowing for easy application in dyeing processes. Additionally, this dye is known for its good washfastness and resistance to fading, which are critical properties for maintaining color integrity in finished textiles. However, like many synthetic dyes, it may pose environmental and health concerns, necessitating careful handling and disposal. Overall, Procion Red MX 8B is widely used in the textile industry for its vibrant hue and durability.
