Reactive Red 120 Use and Manufacturing

Methods of Manufacturing

Using H acid, cyanuric chloride, p-phenylenediamine and anthranilic acid as raw materials, cyanuric chloride is condensed with H acid, then condensed with p-phenylenediamine, and then the anthranilic acid is diazotized , Coupling with the condensate to get the product.

Uses

Mainly used for dyeing and direct printing of cotton cloth and viscose fiber, and suitable for dyeing polyester/cotton and polyester/viscose blended fabrics
