Multifunctional dispersant chelating agent HA-AL
Fractions Organic polymers Ionic property Anionic type External view Colorless clarifying viscous liquid pH value 8~9 (5% aqueous solution) Solubility Tt can be diluted in any proportion with cold water or warm water. Stability This product is very stable for all kinds of acids, alkalis and non-ionic products at common concentrations in dyeing solutions. Compatibility Compatible with anionic and nonionic products. Precipitates can be precipitated in acidic or neutral solutions with various cationic additives.
HA-AL can be used as protective colloid and complexing agent in the dyeing process of cellulose fiber and polyester/cellulose fiber blended fabric. It can prevent precipitation caused by hard water and other impurities during dyeing process, and can be used for pre treatment scouring.
This product is different from ordinary softener. It does not react with metal ions in dyestuff and changes the color. It can be used as a soaping agent for reactive dyes, and the effect is more obvious in lake blue and bright red .
1.Dyeing of polyester / cotton blended fabric
Usually cotton impurities dissolved in acidic medium are easy to form precipitation in alkaline dyeing vat after polyester partially dyed grey fabric. Because of its dispersing and complexing properties, dosage this product can prevent such precipitation, especially in the process of dyeing. The product was concentrated at 1~2 g / L and added at the initial stage of dyeing.
2. Dyeing of cotton fabric with vat dyes
Because of its protective colloid effect in alkaline dyeing solution and its obvious complexation with calcium and magnesium ions, it is very suitable for dyeing cotton fabric with VAT dyes. No special protective colloid or complexing agent should be added after using this product. In the working fluid, the concentration of this product is 1~3 g / L.
3. Dyeing of cotton fabric with reactive dyes
When dyeing with reactive dyes, all kinds of EDTA complexing agents can not be used because the complexed metal ions can be dissolved from many dyes, thus reducing the color fastness of dyed fabrics. On the contrary, HA-AL does not invade metal complex dyes, so the same concentration can be used to replace polyphosphate in reactive dyeing process.
