Appearance: Yellow-green dispersion liquid
Ionicity: Non-ionic
Fluorescent hue: Bluish-violet light
Applications
It is mainly used for whitening and brightening polyester, polyester-cotton, polyester yarn and polyamide. It has a blue-violet hue and is suitable for dip dyeing and pad dyeing, and is mostly used in low-temperature pad dyeing processes (100-180℃).
| Product | Appearance | Ionicity | Whiteness Performance | Main Difference |
|---|---|---|---|---|
| PS-1 | Yellow-green dispersion liquid | Non-ionic | High whiteness | Better sublimation fastness, high temperature |
| PS-2 | Yellow-green dispersion liquid | Non-ionic | High whiteness | Standard type, suitable for pad-dyeing processes,lower temperature |
*Note: PS-1 offers additional sublimation fastness based on PS-2, making it suitable for applications requiring higher heat resistance.*
Reference dosage
For dip dyeing of polyester and polyester-cotton, the addition amount is 0.2-0.5%; for pad dyeing, the addition amount is 1-5g/L.
Package & Storage
10kg or 25kg/ fiber drums. It can be packed in other forms according to user's requirements.
Shelf life: not more than 24 months in the room temperature.
Cautions:
1.If suspension liquid is found precipitated and separated, just shake it before use, which does not affect the use effect.
2.Please note that use this product within its yellow spot, i.e. pad dyeing ≤5g/l, dip dyeing ≤0.8% (o.w.f). If use this product beyond its yellow spot, it will be easy to become yellow.
