| Chemical Properties | Reddish brown powder. Slight change of color and light when stained with iron ions, big change when stained with copper ions. | ||||||||||||||||||||||

| 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. In printing and discharge the impression that can be used while he’s as white agent, can not adapt to the ferrie sulfate-potassium thiosulfate
