Properties and Applications

Red. The dark red powder appearance. Dye bath of iron ion in light of the impact is not big, encounter copper ions that change color. Dyeing appropriate pH value for 4 ~ 5. When in dyeing and printing alkaline resistance is poor. The dyes light yellow color, and the fastness is better. Suitable for all the dyeing method, dye vinegar fiber, colored light and polyester similar, the sun is good fastness, in dye three vinegar when fiber color light yellow, in dye nylon 6 and nylon 66, color is blue, shallow color to dye. But in the polyester/cotton blended fabric printing directly.
