Acid Orange 67 has a high affinity for neutral, medium light fastness and wet fastness, high fixation rate, good dyeability of flower lid, suitable for polyamide dyed in dark, also suitable for leather coloring.
It shows excellent affinity and levelness on protein fibers such as wool and silk, while also working well on nylon. Its even dye uptake ensures uniform color distribution without patchiness.
Yes, Acid Orange 67 can be easily blended with other acid dyes to achieve customized shades. It is often used in combination with red or yellow dyes to expand the shade range for textiles.
