Usage

Description

Sulphur Orange 1 is a yellow orange to red orange colored dye, which appears as a yellow brown powder. It is insoluble in water but has good solubility in sodium sulfide solution, resulting in a yellow orange color. The dye is slightly soluble in concentrated sulfuric acid and experiences a slight change in dyeing content when in an alkaline insurance powder solution. When exposed to sodium hypochlorite solution, the dye almost completely fades. Upon the addition of concentrated sulfuric acid, the color changes from yellow brown to brown.

Uses

Used in Textile Industry:
Sulphur Orange 1 is used as a dye for textiles, providing a vibrant and long-lasting color to fabrics. Its moderate to severe resistance to acid and alkali, as well as its light fastness, make it a suitable choice for various textile applications.
Used in Leather Industry:
Sulphur Orange 1 is used as a dye for leather, offering a durable and attractive color to leather products. Its resistance to fulling, perspiration, and soaping ensures that the color remains intact even under harsh conditions.
