Usage

Description

REACTIVE BLUE 160 is a navy blue powder dye with a solubility of 100 g/L at 50°C. It is known for its high dye affinity and good light fastness, oxygen bleaching, perspiration fastness, and soaping properties. The dye's color changes in the presence of iron ions, and it remains largely unchanged in light when exposed to copper.

Uses

Used in Textile Industry:
REACTIVE BLUE 160 is used as a dye for cotton, hemp, viscose, paint/cotton, and polyester/stick blended fabrics. Its high affinity and good fastness properties make it suitable for dyeing and printing applications.
