Basic green 1

Powder properties

Basic green 1 powder Appearance is blue flashing golden sand powder, slightly soluble in cold water, can only be dissolved in the 98 ℃ hot water 8 g/L, but easy to dissolve in alcohol, all green. The dye was yellow color in sulfuric acid, dilute after to green; It is orange in concentrated nitric acid. Its aqueous solution plus sodium hydroxide has pale green precipitation, plus hydrochloric acid into red yellow. Dyed on silk or acrylic fiber are bright green, slightly yellow in tungsten filament light.

powder shade is brilliant green.

Liquid properties

The appearance is mostly a thick liquid of dark green to copper color, with good water solubility (about 100g/L at 25℃), good compatibility with water and ethanol, and the solution is bright green; the pH value is usually 2.5–3.0 (10g/L aqueous solution, 25℃), stable in acidic systems, and prone to precipitation in the presence of strong alkali.

In liquid form, no dissolution and grinding is required, the dispersion is fast, and the color is uniform, suitable for continuous and automated production; for nylon high-temperature (120℃) dyeing， the color stability is stable, and it can be combined with cationic blue to produce fruit green； however, the sunfastness is relatively low (usually 1–2 grades), and attention should be paid to post-treatment or re-combination.

Liquid Shade is bright green‍.

Applications

• ‍Textile dyeing: Suitable for acrylic (stable color light for high-temperature dyeing), silk, wool, tannin-mordanted cotton, diacetate fibers, etc.; can be dyed separately in bright green, or combined with cationic blue for fruit green dyeing, used for coloring knitted and woven fabrics and yarns.
• Paper making and cultural products: Used for color addition in cultural paper, paper brushing coloring, packaging paper and cardboard dyeing, enhancing the brightness and recognition of paper.
• Wood and artificial boards: Suitable for medium-high density boards, particle boards, etc., with good solubility in glue, can be directly added to the adhesive to achieve uniform coloring of the boards, used for furniture, decorative boards, etc.
• Other fields: Used for coloring leather, hemp, bamboo, wood, grass products.‍
