Washing-Off
Dye-Fixing Agent
A cationic after-treatment that binds to dye already on the fibre, improving wash and water-spot fastness.
Process stage & fibres
| Process stage | Washing-Off |
|---|---|
| Fibres suited | Reactive-, direct- and some acid-dyed cellulosic and protein fibres. |
Function
This product is applied after dyeing to improve wash and water-spot fastness. It binds to dye that is already on the fibre, making it less soluble in water, so it does not bleed out in later washing. It does not add colour or change the shade, it locks in what dyeing has already produced.
Typical applications and what it solves
- Poor wash or water-spot fastness on light-to-medium shades
- Colour bleeding in laundering after otherwise correct dyeing and soaping
- Direct- or acid-dyed lines that need a wet-fastness boost without redyeing
