Formaldehyde-free Red and Black fixing agent HF-8 is cationic multi-polymer. It can form water-insoluble macromolecular with anionic dyes. It can improve wash fastness and rub fastness of fabrics when combined with fiber. Different from common formaldehyde-free fixing agent, this product is designed for all kinds of dyes and enjoys excellent fixing efficiency with very small dosage, especially for soak fastness in boiling water.
◎ Has no free formaldehyde or combined formaldehyde, meeting environmental
requirement.
◎ Can obviously improve wash and rub fastness of fabrics after fixation.
◎ Outstanding soak fastness in boiling water.
◎ Particularly prominent color fixing ability to red and black dyes.
◎ Has no effect on brightness of dyed fabrics, little effect on color shade.
Appearance: yellowish to yellow transparent liquid
Ionicity: cationic
pH value: 5.5-7.5 (1% aqueous solution)
Solubility: can be diluted with water by any ratio
Used for dyeing and printing of reactive, direct, sulfur and acid dye.
◎ Very high fixing efficiency, can be used directly or after being diluted 1:4-7 by water..
◎ Immersion method: HF-8: 0.3-0.8% (o.w.f)
Liquor ratio: 1:10-1:20
pH value: 5.0-7.0

◎ Padding: HF-8: 3-8g/L
Note: The dosage of HF-8can be changed according to deep color or light color, higher dosage for deep color and less dosage for light color.
This product enjoys good wash fastness with just small dosage. If better soak fastness in boiling water is needed, please increase dosage a little.
Kindly Reminder: for blue and green dyes, formaldehyde-free blue and green fixing agent HF-1 is better.
