Textile UV sunscreen with titanium dioxide

Titanium dioxide (for textile use) CAS #: 13463-67-7 15867120050 0571-85351209 Mr. Hsu titanium dioxide (VK-T25F) used in the textile pulp inside, through the perfect combination of starch and improve the overall performance of weaving yarn, reducing The amount of PVA, cooking time is short, reduced pulp costs and improve sizing efficiency, but also solve the difficult of PVA desizing, environmental pollution and many other issues. Titanium dioxide (VK-T25F) yarn in mainly substitute PVA, play stick along hairiness, fill the gap, and reducing warp breaks, the role of lubrication. Technical Specifications: Item Index Model VK-T25F Appearance white fluffy powdery hydrophilic surface properties PH 6-8 rutile crystalline average primary-particle size, nm 20-30 specific surface area, the former m2 / g 50-200 deal with content%> 99.9 surface treatment agent 1% (textiles for nano processing) Loss on drying 105 ℃, 2h (%) ≤0.5 Loss on ignition (%) ≤1.0 Application: titanium dioxide (VK-T25F) used in the textile sizing procedure: 1, mashing process should maintain the original viscosity. 2, the parameter sizing machine remains stable. 3, the first titanium dioxide (VK-T25F) of 20% liquid dispersion (A). 4, the amount of titanium dioxide powder: 0.5-2% by weight of the starch. (Where the starch weight = + instead of the original amount of starch in the amount of starch PVA). 5, cotton sizing using the same amount of starch instead of off PVA, other components remain unchanged. 6, appropriate to the pulp barrels by adding a predetermined amount of water when the pulp, then shake the liquid (A) sizing agent. 7, a predetermined amount of starch, medium-speed stirring ten minutes and then put into other raw materials. 8, heating boiling syrup, atmospheric bored bored pulp slurry for 30 minutes or high pressure for 20 minutes. Note: 32 yarn per barrel with a liquid slurry (A) 2 kg, 40 yarn per barrel with a liquid slurry (A) 3 kg, 5 kg 60 yarn reservations PVA, PVA other starch instead of out with the same amount, with a liquid ( A) 3.5 kg. If the liquid slurry formulation polyacrylate slurry, the slurry should be heated to 50 ℃ after adding this nano additive. Addition: 900 kg pulp + 2--8 kilogram of liquid A package: 20 kg / barrel
