◆ Main component stilbene derivatives
◆ technical index
Appearance: light blue dispersion
Ionicity: non-ionic
Color light: blue-purple light and blue
Solubility: evenly dispersed in water
PH (1% aqueous solution): 5.0-7.0
◆ Performance and characteristics
It has the characteristics of strong fluorescence, high whiteness, good light resistance and washing resistance, and good sublimation fastness.
◆ Scope of application
Mainly used for whitening and brightening polyester and its blended fabrics.
◆ How to use
1. Pad dyeing hot melt method:
Dosage: 1-20g/L (adjusted according to sample test)
Process flow: two dip and two rolling (rolling rate 70%) → pre-baking (100°C) → baking (180-200°C, 20-30 seconds)
Note (1) After the fabric is pre-treated, it must be washed to prevent residual alkali on the fabric.
2. dip dyeing method:
PS-A 0.1-0.8% (owf); bath ratio: 1:10-30; PH: 5-10 (weakly acidic water bath is particularly good)
Process: 120-130°C×30-60min → washing → drying → shaping
