CAS 12222-69-4
:Disperse Black 9
Description:
Disperse Black 9, with the CAS number 12222-69-4, is a synthetic organic dye primarily used in the dyeing of synthetic fibers, particularly polyester. It belongs to the class of disperse dyes, which are characterized by their ability to dissolve in water at high temperatures, allowing them to penetrate hydrophobic fibers. This dye exhibits good lightfastness and washfastness, making it suitable for applications where durability is essential. Disperse Black 9 is typically applied in a dispersion form, requiring specific conditions for optimal dyeing, such as elevated temperatures and the presence of dispersing agents. The dye is known for its deep black color and is often utilized in the textile industry for producing dark shades on fabrics. However, as with many synthetic dyes, there are environmental and health considerations associated with its use, prompting ongoing research into safer alternatives and improved dyeing processes. Proper handling and disposal practices are essential to mitigate any potential risks associated with its use.
