Usage

Description

Amanil developed black BHSW is a dye that exhibits unique color properties and reactions to different chemicals. It is characterized by its red light purple color in alcohol and violet blue color in water. When treated with strong sulfuric acid, it turns blue and forms a purple precipitate upon dilution. The dye solution changes to blue when hydrochloric acid is added and turns red light purple when sodium hydroxide solution is introduced.

Uses

Used in Textile Industry:
Amanil developed black BHSW is used as a dye in the textile industry for coloring fabrics. Its unique color properties and reactions to chemicals make it suitable for creating vibrant and long-lasting colors on various types of textiles.
Used in Acid and Alkali Resistance Applications:
Amanil developed black BHSW demonstrates good acid and alkali resistance, with an ISO rating of 4 for both properties. This makes it suitable for use in applications where the dye needs to withstand exposure to acidic or alkaline environments without losing its color or integrity.
Used in Light Fastness Applications:
With an ISO rating of 1 for light fastness, amanil developed black BHSW is suitable for use in applications where the dyed material will be exposed to sunlight or other light sources. This ensures that the color remains vibrant and does not fade over time.
Used in Soaping and Water Applications:
Amanil developed black BHSW has an ISO rating of 2 for both soaping and water properties, indicating that it can maintain its color and integrity when exposed to soap or water. This makes it suitable for use in applications where the dyed material will come into contact with water or soap, such as in laundry or cleaning processes.
Used in Fading and Stain Applications:
Amanil developed black BHSW has an ISO rating of 4 for both fading and stain properties, which means it is resistant to fading and staining. This makes it suitable for use in applications where the dyed material needs to maintain its color and not transfer to other surfaces or materials.

Preparation
