1. Protective Textiles – Overview from Research and Patented Innovations Seminar Presentation By: Vinod Department of Textile Technology

2. Introduction Protective textiles safeguard humans from physical, thermal, chemical, and biological hazards. They combine high-performance fibers, coatings, and smart materials.

3. Major Protection Categories • Ballistic and Fragment Protection • Stab and Cut Resistance • Thermal and Flame Resistance • Chemical and Biological Barrier • Electrical and Radiation Protection • Multi-hazard Protection

4. Core Materials Used • Aramids (Kevlar®, Twaron®) • UHMWPE (Dyneema®, Spectra®) • PBO (Zylon®) • Ceramics • Shear-Thickening Fluids • Nanofibers & Graphene

5. Textile Structures • Woven or Knitted High-performance Fabrics • Nonwoven Layers • Laminated Composites • 3D Spacer Fabrics • Hybrid Multilayers

6. Research & Innovation Outcomes • STF-treated Kevlar fabrics • Auxetic structures • Nanofiber membranes • Graphene coatings • Smart textiles with sensors • Self-cleaning surfaces

7. Example Patented/Commercial Products • Kevlar®, Twaron®, Dyneema®, Gore-Tex® • STF-treated aramid fabrics • Graphene-based EMI shields

8. Testing & Standards • Ballistic – NIJ 0101.06 • Cut – EN 388 • Flame – ISO 11612 • Chemical – ASTM F739 • Biological – ISO 16604 • Arc Flash – ASTM F1506

9. Challenges & Future Scope • Balancing protection, weight, comfort • Cost of advanced fibers • Multi-hazard protection • Sustainable and smart textiles

10. Conclusion Protective textiles are evolving with nanotech and smart materials. Focus on lighter, stronger, smarter solutions. Applications: defense, industry, healthcare.
