Usage

Description

Reactive Red Brown K-B3r is a claret-colored, palm black powder dye that exhibits unique chemical reactions when exposed to strong acids like sulfuric and nitric acid. It has the ability to change color under different conditions, making it a versatile dye for various applications.

Uses

Used in Textile Industry:
Reactive Red Brown K-B3r is used as a dye for cotton, viscose, and silk fabrics. Its ability to produce a red sauce color in the dye water solution and maintain this color even after the addition of sodium hydroxide makes it a popular choice for direct dyeing and printing methods.
Standard:
The dye has been tested and meets the following standards for light fastness, oxygen bleaching, perspiration fastness, soaping, fading, and staining:
Light Fastness: ISO 4-5
Oxygen Bleaching: ISO 5
Perspiration Fastness: ISO 4-5
Soaping: ISO 4-5
Fading: ISO 3-4
Stain: ISO 4-5 (100℃)
These standards ensure that Reactive Red Brown K--B3r provides consistent and reliable color results in the textile industry.
