Usage

Description

DISPERSE YELLOW 49 is a light brown powder that exhibits bright green light yellow color. It is soluble in acetone and ethanol, and its dyeing process is affected by the presence of copper and iron ions. The dye is suitable for a pH value of three to five and is not recommended for high temperature and high pressure dyeing. It is prone to decomposition in high temperature alkaline conditions. The optimal temperature for hot melt dyeing is 195-200°C, while the carrier dyeing method is applicable at 100°C with pH control around five.

Uses

Used in Textile Industry:
DISPERSE YELLOW 49 is used as a dye for various fibers, including nylon, acrylic, polypropylene, polyester, and polyamide. It provides light yellow color with good fastness properties. The dye can be used for direct printing on polyester black silk ribbon and polyamide fiber or vinegar due to its alkali sensitivity.
