Usage

Description

Sulphur Brown 10 is a red-brown powder that is insoluble in water but soluble in sodium sulfide solution for brown and slightly soluble in concentrated sulfuric acid. It is a dye that is primarily used for cotton, hemp, viscose, and vinylon/cotton blended fabric dyeing, and occasionally in leather and paper dyeing.

Uses

Used in Textile Industry:
Sulphur Brown 10 is used as a dye for cotton, hemp, viscose, and vinylon/cotton blended fabrics due to its ability to provide a brown color. It is favored for its moderate acid resistance, severe alkali resistance, and good light fastness.
Used in Leather Industry:
Sulphur Brown 10 is used as a dye for leather, providing a brown color and offering moderate acid resistance and severe alkali resistance.
Used in Paper Industry:
Sulphur Brown 10 is used as a dye for paper, offering a brown color with moderate acid resistance and severe alkali resistance.
Standard:
The standard for Sulphur Brown 10 includes the following ratings:
Acid Resistance: Moderate (ISO 3, AATCC 3-4)
Alkali Resistance: Severe (ISO 4, AATCC 5)
Light Fastness: 3-4 (ISO, AATCC)
Fulling: 4 (ISO, AATCC)
Perspiration Fastness: 4 (ISO, AATCC)
Soaping: 4 (ISO, AATCC)
