| Chemical Properties | Orange-yellow powder. Easily soluble in water, aqueous solution is dark yellow, slightly sensitive to hard water. Slight change of color and light when met with copper ions, yellowish and dark when met with iron ions. | | Uses | Direct yellow 106 is a good dyeing agent for cotton fabrics. | | Preparation | 2-(2-Sulfo-4-nitrostyryl)-5-aminobenzenesulfonic acid diazo, and 4-Aminonaphthalene-1-sulfonic acidcoupling, and then the oxidation into three thiazole compounds, garnish with glucose and sodium hydroxide will 2 Moore was reduced to a single three compounds azo dyes. | | Properties and Applications | red light yellow. Orange yellow powder. Soluble in water for deep yellow, hard to a little sensitive. Dyeing, copper ions in a slight change color shade; Iron ion in dark colored light yellow. Resistance to various compounds and does not affect the application performance. Used for cotton, viscose and their blended fabric dyeing, is not used for printing. Can and dispersal dyes with bath dyeing polyester/cotton blended fabric.
