Usage

Description

Direct Green 59 is a deep purple powder that is soluble in water, resulting in a green solution. It is primarily used for dyeing cotton, viscose, and their blended fabrics, as well as for printing on cotton or viscose fabrics directly. Additionally, it can be used for dyeing polyester/cotton and polyester/stick blended fabrics in a one-bath process.

Uses

Used in Textile Industry:
Direct Green 59 is used as a dye for cotton, viscose, and their blended fabrics due to its ability to produce a vibrant green color. It is also used for printing on cotton or viscose fabrics directly, providing a convenient and efficient method for color application.
Used in Polyester/Cotton and Polyester/Stick Blended Fabrics:
Direct Green 59 is used as a dye for polyester/cotton and polyester/stick blended fabrics in a one-bath process, simplifying the dyeing process and reducing the need for multiple steps.
Standard:
Direct Green 59 meets the following standards for various properties:
Acid Resistance: 1 (ISO), 2 (AATCC)
Alkali Resistance: 4 (ISO and AATCC)
Light Fastness: 4 (ISO), 4-5 (AATCC)
Soaping: 4 (ISO), 4-5 (AATCC)
