Summary
Green synthesis of zinc oxide nanoparticles (ZnO-NPs) and cold plasma treatment significantly enhance UV protection factor (UPF) in textiles for workwear. This eco-friendly approach offers superior performance over chemical methods, improving safety and productivity.
Area of Science:
- Materials Science
- Textile Engineering
- Nanotechnology
Background:
- Textiles are crucial for workwear safety and comfort.
- Nanotechnology offers novel functionalities for textiles.
- Developing UV-protective workwear is essential for worker health.
Purpose of the Study:
- To develop UV-protective textiles for workwear applications.
- To utilize zinc oxide nanoparticles (ZnO-NPs) synthesized via chemical and green methods.
- To investigate the efficacy of cold plasma treatment for enhancing UV protection.
Main Methods:
- Synthesized ZnO-NPs using chemical and green methods.
- Characterized ZnO-NPs using microscopy, spectroscopy, XRD, and DLS.
- Treated textiles with ZnO-NPs using pad-dry-cure-pad method, with citric acid or cold plasma for adhesion.
- Measured Ultraviolet Protection Factor (UPF) and air permeability before and after washing.
Main Results:
- XRD confirmed ZnO-NP presence; band gaps were ~3.27-3.28 eV.
- UPF values increased significantly after treatment, especially with green ZnO-NPs and cold plasma (up to 658).
- Air permeability improved post-treatment, with cold plasma showing notable increases.
- UPF decreased after five wash cycles, but treated textiles retained higher protection.
Conclusions:
- Green synthesis of ZnO-NPs is a cost-effective and sustainable alternative.
- Cold plasma treatment combined with green ZnO-NPs provides superior UV protection for textiles.
- Enhanced UV protection in workwear textiles contributes to improved worker safety.
