Objective
Study how to coat Zinc Oxide Nano which methods give the most effective ways.
Equipments
- White Woven Fabric (TC Fabric)
- Electronic Iron
- Padding Machine
Chemicals
- ZnO nano 2000 ppm dispersant
- Spray Strach
How to Coat
| Experiment | Chemical use | How to coat |
| 1 | ZnO nano 2000 ppm | Spray + Iron |
| 2 | ZnO nano 2000 ppm + Spray Starch | Spray + Iron |
| 3/1 | ZnO nano 2000 ppm | Soak 5 min. →Padding |
| 3/2 | ZnO nano 2000 ppm | Soak 5 min. →Padding |
| 4 | ZnO nano 2000 ppm | Soak 1 hr →Hanging |
| 5 | Control |
Test Results
| Experiment | Quantity of ZINC (mg/kg) |
| 1 | 612.43 |
| 2 | 497.44 |
| 3/1 | 1,202.83 |
| 3/2 | 836.14 |
| 4 | 2,287.63 |
| 5 | 20.56 |

Summary of Test Results
The experiment shows that Ex. 4 contain the most Zinc quantity, so it is concluded that Ex. 4 is the most effective method. Soaking white woven fabric in ZnO Nano 2000 ppm dispersant for 1 hour, Zinc Oxide will best bond with cellulose fiber in cotton most.
Pad-dry-cure Method
- Soak cotton in ZnO (2 %) dispersant+ Acrylic binder (1 %) 5 min.
- Put cotton through Padding machine for speeding 15 metre/min. with pressure 15 Kgf/cm2
- Through dry machine and cured for 3 min at 140 °C
- Soak fabric 5 min inSodium lauryl sulfate 2 g/L to wash off ZnO nano
- Rinse off with water for 10 times
