Properties and Applications

Bright red blue light. Dark red powder, soluble in ethanol, acetone, benzene. In dye in bath of iron, copper, calcium, magnesium ions on no influence on all light. Dyeing appropriate pH value for 3 ~ 7, in dyeing and printing alkali not when. The dyes as dark blue light red, and all the good fastness, levelness passable, suitable for all kinds of dyeing methods. The liquid should join sulfuric acid or formic acid will of the pH value of the liquid transferred to the five or so. The color with vinegar fiber with polyester similar, dyeing brunet, in three vinegar on a little yellow light fiber. In a blue light on polyamide, in acrylic dyeing rate and low, can be used for polyester fiber or vinegar of direct printing, also can be the impression of the discharge printing. Suitable for superfine fiber dyeing currently.
