Description
Molecular Formula: C6H4N2O5
Molecular Weight: 184.10
CAS No.: 1326-82-5
H. S. Code: 32041911
Standard: HG/T3427-2001
Appearance: Black granular crystal with metal gloss.
Packing: 25kg/iron drum/PP bag/carton box.
Usage:
Mainly used dyeing on cotton, also used dyeing on cambric and leather
Sulfur dyes are the most commonly used dyes manufactured for cotton in terms of volume. They are cheap, generally have good wash-fastness and are easy to apply. The dyes are absorbed by cotton from a bath containing sodium sulfide or sodium hydrosulfite and are made insoluble within the fiber by oxidation. During this process these dyes form complex larger molecules which is the basis of their good wash-fastness.
