Direct Black 19 Dyeing Fastness(grade)
Direct Black 19 Properties and Applications:
green and black. Black powder. Soluble in water for green light black, solubility of 100 g/L (80 ºC), slightly soluble in ethanol and acetone. The strong sulfuric acid in the green light for black, dilute red after black precipitation; In nitric acid to dark brown. Dyes and microstructure of sulfuric acid solution 10% red; Add thick sodium hydroxide solution for green light blue. Copper ions in dyeing color shade the green, iron ion a slight change in color.
Applications:
Used in viscose of dyeing and printing. In the cotton knitwear, blankets, flannelette, silk, viscose, silk that the fabric, wool/viscose fiber blend fabrics can be used. Can also be used in leather, paper and electrochemical aluminum color.
