DISPERSE YELLOW 49 Usage And Synthesis

Properties and Applications

Bright green light yellow. Light brown powder, soluble in acetone and ethanol. Dyeing process meet copper, iron ion to the dyeing color after a certain effect. The dye to adapt to the pH value for three to five. The dye is not suitable for high temperature under high pressure dyeing. Dye in the high temperature alkaline conditions easy decomposition, used for hot melt dyeing method of optimum temperature for 195 ~ 200 ℃, 100 ℃ is applicable to the carrier dyeing method, pH control in the five or so. Dye can get similar three vinegar fiber in the light of the two vinegar fiber. Dyeing nylon get light yellow, dye acrylic and polypropylene fiber dyed have to light yellow, and all the good fastness. In polyester Black silk ribbon and polyamide fiber or vinegar can be directly printing, because the dye the alkali sensitive, can the dye printing color.
