Direct orange 26 is Orange to red light yellow red colourful. Red brown powder. Soluble in water for red orange brown, solubility of 10 g/L (80 ℃), and adequate soluble in alcohol for gold orange. The strong sulfuric acid for colourful red, orange to red appear after diluted red precipitate. The dye solution to join strong sodium hydroxide solution into orange brown; Add a 10% sodium hydroxide solution become yellow; Join strong hydrochloric acid have red precipitation appear; And 10% sulfuric acid to become red. Is sensitive to that fights. 

Appearance is brown powder. Water soluble, sensitive to hard water. Dissolved in water is red orange, slightly soluble in alcohol, golden orange. It is bright red in concentrated sulfuric acid, red orange to red precipitate after dilution; dark orange yellow precipitate in concentrated nitric acid; insoluble in concentrated sodium hydroxide, diluted to light golden yellow after dilution; orange-red in concentrated ammonia water The aqueous dye solution is concentrated with concentrated hydrochloric acid and has a red precipitate.

Direct Orange 26 Application:

Dyeing cotton or viscose for red orange, can be used for cotton or viscose direct printing, also can be used for silk, wool, Polyvinyl alcohol and polyamide fiber fabric dyeing, can also be used in leather and pulp dyeing. Exhaust dyeing is very good.

Use condition:

1.Direct Orange 26 is used to dye cotton or viscose fiber to get red and yellow. It has poor transferability and is sensitive to salt. It should be slowly heated when dyeing and salt is added to control the dyeing to obtain uniform color. The dyeing rate is very good. After the dyeing stage, the dyeing solution should be naturally cooled to 60 ° C, which is beneficial to the dye exhaustion.

2. It is used for dyeing rich fiber, the dyeing rate is good, the color light is slightly yellower than cotton. It can also be used for the dyeing of silk, wool, vinylon and nylon. When dyeing silk and wool, it is dyed with Canadian dollar powder and acetic acid. Nylon can be used as a dyeing agent for dyeing. When dyeing vinylon, the dyeing rate is poor, and the color light is slightly yellower than cotton and viscose fiber. When cotton, viscose fiber and other fibers are dyed in the same bath, silk is lighter than cotton, and wool is obtained. The color is light and yellow, the diacetate is slightly stained, and the polyester and acrylic are not stained.

3.It can be used for direct printing on cotton or viscose fabrics. Urea and disodium hydrogen phosphate should be used when printing deep patterns.

Modulation of color paste. It can also be used for direct printing of silk fabrics, in the same way as cotton and viscose.

4.Direct Orange 26 is a commonly used dye for viscose fabric dyeing and printing. It is often used in combination with yellow, red, gray, brown, etc., to adjust the color and increase the chromatogram. When dyeing light color, use Alkaline dyeing bath, dyeing faster, easy to cause color, so generally avoid the use of alkaline dye bath, and add emulsifier OP as leveling agent, to improve.

Packing:

20 or 25kg/compound bag, carton box, iron drum, fiber durm for powder dye and 1000kg/tank for liquid dye
