The provided range of Direct Orangeis a huge volume particle. These dyes not just create a salt-like bond alongside the fleece ï¬bre yet, in addition, attached to the ï¬bre by intermolecular powers. They have properties lying in a moderate situation between those of the leveling and processing colors with intermediate sub-atomic size. The scope of Direct Orange can be classified as milling acid dyes, equalizing dyes, super-milling dues, and fast acid dyes. These require significant measures of solid acids alongside Glauber's salt to accomplish great exhaustion. Under the high centralization of corrosive high convergence of cationic ammonium, groups are produced in the fleece and the colors have quick strike for the fleece.
