applications of nano technology

  1. 1. APPLICATIONS OF NANOTECHONOLOGY IN TEXTILE INDUSTRIES
  2. 2. CONTENTS  Introduction Possible Clothing Issues Different Structure Of Nano Particles Types Of Nano Particles Textile Applications Future Prospectives
  3. 3. Possible ClothingPossible Clothing Issues:Issues: • Shrink • Fade • Stain • Odor • Color • Too Big • Too Small • Too Hot • Too Cold • Wrinkles
  4. 4. All of these issues canAll of these issues can be “fixed” throughbe “fixed” through Nanotechnology!Nanotechnology!
  5. 5. NANOTECHNOLOGY The study of control of matter on atomic and molecular level Involves engineering on a small scale to create smaller, cheaper, lighter and faster devices that can do more things with less raw materials. Nano-scale has generally been taken to lie from 0.2nm (atom) to 100nm.
  6. 6. DIFFERENT STRUCTURES OF NANO PARTICLES
  7. 7. NANOFIBRES Nano-fibres are generally taken to be fibres with a diameter less than 1μm (100nm). Electrospinning is the major fibre production method used to make nano- fibres. By manipulation of the electro-spinning conditions, micro-filaments can be produced
  8. 8. Electro-spinningElectro-spinning Nano-fibresNano-fibres
  9. 9. NANOFIBRES Nano-fibres produced from synthetic fibre materials can be formed with a high surface area to volume ratio and small pores sizes in fabric form.
  10. 10. USES OF NANO FIBERSUSES OF NANO FIBERS The potential end uses for such nano-fibres are in filtration, wound dressings, tissue engineering, nano-composites, drug delivery devices sensors.
  11. 11. NANO-COMPOSITES FIBRES Nano-composite fibres consist of nano-fibres. The particles may be spheres, fibrils and by varying the amounts, their alignment, and distribution within the nano-fibre improvements in the mechanical, electrical, optical or biological properties may be obtained.
  12. 12. NANO-COMPOSITES FIBRES
  13. 13. CARBON NANO-TUBES • The carbon nano-tubes essentially consist of tiny shells of graphite rolled up into cylinders, either as single tubes or multiple tubes joined together.
  14. 14. Carbon Nano-tubes The carbon nano-tubes exhibit remarkable properties: tensile strength thermalconductivity Electrical conductivity
  15. 15. Nano-coated fibres • Nano-coating of textile fabrics, complete finished garments or shoes can be obtained by plasma polymer treatment.
  16. 16. Nano-coatingNano-coating Plasma TreatmentPlasma Treatment
  17. 17. FUNCTIONAL HYGIENE Antibacterial reagents used are: Ag, Chitosan, SiO2 (as matrix), TiO2, ZnO
  18. 18. INCREASE DURABILITY Al2O3, SiO2, CNT, ZnO, Polybutylacrylate
  19. 19. ELECTRO CONDUCTIVE AND ANTISTATIC Carbon black, Carbon nanotubes (CNT), Cu, Polypyrrole, Polyaniline
  20. 20. FIRE PROOF CNT, Boroxosiloxane, Montmorillonite (nano clay), Sb3O2
  21. 21. SELF-CLEANING/ DIRT AND WATER REPELLENT CNT, Fluoroacrylate, SiO2 (as matrix), TiO2
  22. 22. UV PROTECTION TiO2, ZnO
  23. 23. MOISTURE ABSORBING TiO2
  24. 24. IMPROVED STAINING /IMPROVED STAINING / REDUCE FADEREDUCE FADE Carbon black, Nanoporous hydrocarbon on Nitrogen coating, SiO2 (as matrix)
  25. 25. FUTURE PROSPECTS The main trust in nano-technologies applied to textiles, clothing and footwear will be to: Improve the properties and performance of existing materials; Develop smart and intelligent textiles with novel functions;
  26. 26. Greatly increase the use of fibres in technical textiles, biomedical and healthcare options; Open up new opportunities for fibres as sensors.
  27. 27. NANO-TECHNOLOGIES OFFER GREAT POTENTIAL FOR THE FUTURE AND COULD RADICALLY CHANGE CONSUMER PERCEPTION OF WHAT CONSTITUTES A “STANDARD” APPAREL FABRIC.
