Usage

Description

Vat Orange 1, Solubilized is a yellow-orange dye in the form of an orange powder. It is soluble in water and exhibits a shallow green-yellow fluorescence under ultraviolet light. This dye is known for its relatively good sun and wet fastness properties, although it may still experience some loss when exposed to sunlight, particularly in woven fabrics.
Used in Textile Industry:
Vat Orange 1, Solubilized is used as a dye for cotton fabric dyeing and printing. Its good sun and wet fastness properties make it widely used in printing and dyeing cloth washable fabrics and furniture, such as curtains, upholstery, and bed linens. It can be applied through direct printing, resist printing, or white discharge printing techniques.
Vat Orange 1, Solubilized is also used for dyeing and printing other types of fabrics, such as viscose, polyvinyl alcohol, polyester, and silk. Its solubility in water and compatibility with various fibers make it a versatile dye for the textile industry.
