Property:
Can combine with the starch perfectly.
Improve comprehensive weaving yarn performance well.
Reduce the useage of PVA and Shorten the time of size cooking.
Lower production costs and enhance the sizing efficiency.
Can replaced the PVA,smooth the hairiness, fill the gaps , reduce the yarn decollation,lubrication action.

Process of using nanometer titanium dioxide in textile size:
1.Keeping the intrinsic viscosity during the process of size mixing.
2.keeping the parameter of sizing machines stability.
3.Dipersing nano titanium dioxie in water (20% wt of TIO2---liquid A )
4.The dosage of titanium dioxide: 0.5-2% of starch weight.
5.Replace equal starch with the PVA in pure cotton sizing,other components remained unchanged.
6.Adding specified amount of water , then mix uniformily.
7.Add specified amount of starch, mixing ten minutes with medium speed ,and the adding other meterials.
8.Heating-up and boiling,and then curing for 30 minutes at ordinary pressure or 20 minutes at high pressure.
Dosage:900 kgs textile size +(2~8) kgs liquid(A)
Packet outfit: 20 kgs/drum
