Product Desciption
BL-II Fluorescent Whitening Agent for Polyester at Low Temperature
I Technical data:
Appearance:cream white or pale yellow dispersion liquid
Shade:blue
Particle size:90%≤2μm
PH value:6-7
Density:1.035±0.02
Ionicity:nonionic
II Applications:
It is mainly applicable to whitening and brightening of polyester fiber and the blends,especially to whitening of polyester fiber knitting at low-temperature(95-100ºC)
III Directions for use and dosage:(only for reference)
1.Exhaust dyeing method of low-temperature absorption:
Dosage:0.3-0.7%(o.w.f)
Liquor ratio:1:10-20
Dyeing temperature:95-100ºC
Dyeing time:30-40min
PH valuc:4.5-5.5 (adjusted with acetic acid)
Procedure:add additive,acetic acid(adjusting PH:4.5-5.5)and BL-II FWA into the dye bath according to the formula, raise temperature to 95-100ºC as the ratc of 2-3ºC/min,keep constant temperature for 30-40min→drop in temperature →washing→dehydration and drying(80-100ºC),its whiteness can meet the use's requirement.If the user has fixing machine,carry out pre-drying(80-100ºC)and curing(170-175ºC,30-40s)after washing and dehydration,then whiteness will be better.
2.Pad dyeing method:
Dosage:1.5-4g/L
Procedure:2dips2nips(pick up:70%)→pre-drying(100ºC)→curing and thermo-fixing(175-180ºC,30seconds)
3.High-temperature and high-pressure exhaust dyeing method:
Dosage:0.2-0.5%(o.w.f)
Liquor ralio:1:10-20
Dyeing temperature:120-130ºC
Dyeing time:30-60min
PH valuc:4.5-5.5(adjusted with acid)
IV Using tips
1.If suspension liquid precipitates and separates after stored for a long period,please fully stir before use.
2.It shall be used within the yellowing spot range of this product,i.e.pad dyeing≤5k/L,exhaust dyeing≤0.8%(o.w.f).It will be subject to yellowing if beyond the dosage range.
V Packaging and Storing:
5kg in plastic drum,20kg/paper carton(4drums).Quality guarantee period is 8-12 months under normal temperature.
