C.I. Direct Red 243 Use and Manufacturing

Methods of Manufacturing

Take o-aminophenol-4-sulfonic acid, 4-methoxyaniline-2-sulfonic acid, J acid, cyanuric chloride and ethanolamine as raw materials. First, diazotize o-aminophenol-4-sulfonic acid and couple with J acid, then diazotize 4-methoxyaniline-2-sulfonic acid, couple with another molecule of J acid, and then couple the two single couplings. Nitrogen compounds are respectively condensed with cyanuric chloride, and finally ethanolamine and cyanuric chloride are condensed for the third time to obtain products. The finished product is obtained by salting out, filtering, drying and crushing.

Uses

Direct light fast red BWS is used for dyeing of cotton, viscose fiber, silk and printing of fabrics. It has excellent light fastness. Especially suitable for one-bath and one-step dyeing of polyester-cotton and polyester-viscose blended fabrics.
