Usage

Description

Mordant Violet 1 is a brilliant purple dye that is soluble in both cold and hot water, as well as in ethanol. It exhibits various color changes when interacting with different substances, such as turning brilliant yellow red in concentrated sulfuric acid and forming a red precipitate upon dilution. When mixed with a dye aqueous solution and sodium hydroxide solution, it results in a brilliant red purple color, which then turns colorless.

Uses

Used in Textile Industry:
Mordant Violet 1 is used as a dye for textiles, providing brilliant purple shades to fabrics. Its solubility in water and ethanol allows for easy application and even distribution of the dye on various types of fibers.
Used in Color Fastness Testing:
Mordant Violet 1 is utilized in testing the color fastness of textiles under different conditions, such as ironing, light exposure, fulling, perspiration, soaping, water, alkali, and acid. The dye's performance is evaluated based on standardized ISO and AATCC ratings, which indicate its resistance to fading or color change under these specific conditions.

Preparation

4-(Diethylamino)benzaldehyde?(1 Moore) and 2-Hydroxy-3-methylbenzoic acid (2 Moore) in sulfuric acid solution condensation, then use nitrous acid oxidation.
