Properties and Applications
colourful red blue light. Purplish red powder. In the strong sulfuric acid to red, no change after diluted; In nitric acid was great red, no change after diluted. The dye solution for blu-ray red, with 1 Moore sodium hydroxide solution into orange red; Continue to join insurance powder and warm, into a shallow dark yellow; Add a boric acid sodium can’t restore the original colour and lustre. In 20 ℃ dye the solubility of 60 g/L; 50 ℃ when solubility of 160 g/L. After dyeing color shade of red light for basket, dye bath containing iron ion colored light basic unchanged, encounter copper ions that colored light turned dark. Mainly used for cotton, viscose, wool, silk, polyamide fiber disseminated and roll dye, also can be used to knot dyeing. Storage stability is poorer.
