Fixing Agent for Acid Dyes SP

[Fixing Agent for Acid Dyes General Information]
Fixing agent for acid dyes will be deposited on the surface of the fiber, plugging the pores of acidic dyes dissolved again, thus reducing the possibility of fading, and generally improving the color fastness 1 ~ 1.5. Based on this, the solid color of the impregnation method is used.

The appearance is generally brown liquid, pH value (1% water solution) 2.0-4.0, anionic, odorless, slightly special smell, taste astringent, deeper color while exposed under light and in air. Soluble in water, soluble in ethanol, acetone and glycerin, almost insoluble in ether, benzene, chloroform and petroleum ether. It has strong hygroscopicity. Decompose in 210 ~ 215 ℃, It can produce insoluble salt with copper, aluminum, iron, tin, chromium and metal salts, and each has its own special color. It is best to use soft water or add 1 g/L 6 sodium phosphate when used.

[Main composition]
Sulphonate condensation polymer.

[General properties]
Appearance: dark brown liquid
Ionicity: anionic
pH: 2±1
Solubility:easily soluble in water
Stability: stable to acid, alkali, electrolytes and hard water

[Color Fixing Agent for Acid Dyes Features and Applications]


1. Especially for wool, nylon, silk and leather with anionic dye-stuffs (acid/metal complex dye-stuffs) while washing, perspiration, light, chlorine and bleeding fastness can be sharply improved after treatment.
2. Excellent dye fixing performance on nylon webbing that is obviously better than other acid dye fixing agents.
3. Slight influence on shades and hand feels that can use in the same bath of dyeing and fixing, which shortens process.
4. Fixing agent for acid dyes has outstanding acid resistance for easy operation.

High concentration fixing agent and can be diluted 1-2 times.
Dye fixing of fabrics with acid/metal complex dye-stuffs.
Pale shades:1-2% (O.W.F)
Medium shades:2-3% (O.W.F)
Deep shades:  3-4% (O.W.F)
