Usage

Description

Disperse Blue 183 is a blue-black powder that is soluble in acetone and DMF. It is a dye used for polyester and their blended fabric dyeing, known for its high lifting force and suitability for dyeing very deep colors and lustre.

Uses

Used in Textile Industry:
Disperse Blue 183 is used as a dye for polyester and blended fabrics, providing high temperature and high pressure dyeing methods suitable for dyeing shallow colors, good levelness, and poor coverage. It is also used in the melt method dyeing for polyester/cotton blends, allowing for direct dyes and one-bath dyeing of step.
Used in Polyester Fiber Dyeing:
Disperse Blue 183 is used for dyeing polyester fibers and superfine printing, offering high lifting force and suitability for dyeing very deep colors and lustre.
Used in Direct Printing on Polyester Fabric:
Disperse Blue 183 can be used for direct printing on polyester fabric, allowing for light color discharge printing.
Note: Disperse Blue 183 is not suitable for dyeing other fibers besides the three vinegar fibers, and its dyeing rate is not high for dyeing three vinegar fibers.
