| Hazard Information | Back Directory | [Chemical Properties]
Light brown powder. Soluble in acetone and ethanol. The presence of copper and iron ions during dyeing may affect the color tone. | [Uses]
DISPERSE YELLOW 49 is suitable for dyeing polyester using the medium-temperature (195-200℃) hot melt method and the 100℃ carrier method. It produces a bright and delicate color with good colorfastness, especially excellent lightfastness. However, it is not suitable for high-temperature, high-pressure methods. It produces a bright yellow with a greenish tint when dyeing diacetate and triacetate fibers, and a pale yellow when dyeing nylon, acrylic, and polypropylene fibers. It can be used for direct printing on polyester, nylon, and acetate fiber fabrics. When dyeing polyester-cotton blends, it does not stain cotton. When dyeing diacetate/viscose blends, it can be used in the same bath as direct dyes. Furthermore, CI disperse yellow dyes can also be used to formulate dyeing and printing paste compositions (composed of dyeing and printing concentrate, thickener, pH adjuster, and water). | [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.
