  1. Nanotechnology in Clothing Consorte | Torres | Villafuerte | Vizconde

  2. History of Clothing • When people first started wearing clothes? - Anthropologists estimate ~100,000 to 500,000 years ago. • The first clothes? - made from natural elements: animal skin and furs, grasses and leaves, and bones and shells.

  3. settled neolithic cultures -woven fibersvs animal hides • history of clothing = history of textiles -weaving, spinning and other techniques and machines • Sewing machine

  4. NANOTECHNOLOGY • It is the application of nanomaterial based on the study and engineering of matter at the scale of nanometers. • “engineering of tiny machines”

  5. Comparative View of the Sizes http://www.nanosilver.com.my/nanotech.asp

  6. NANOTECHNOLOGY • Advantages: -Can actually revolutionize a lot of electronic products, procedures, and applications -Can benefit the energy sector -Can benefit the manufacturing sector -Can create ‘smart drugs’ for medicinal means

  7. NANO-TEXTILES • Application of nanotechnology • Involves dealing with nanofibers at the atomic and molecular levels in order to tweak their properties • Examples: - water-resistant and dirt-free clothes - odor less socks - smart clothes that can perform UV protection, wrinkle resistance, color durability, flame retardancy and better thermal performance

  8. Antimicrobial Nanosilver • Widely used in sports clothing to eliminate unpleasant odors from sweat • It has silver nanoparticles which are antimicrobial in nature • Tiny silicon fibers, titanium oxide

  13. Personal Climate Control • ClimaWare such as shoes, jackets and helmets can serve as an ACs or heaters at the press of a button • Light-weight • Can be used in defense, health care, athletics, and other personal climate control uses • The principle behind is the Peltier Effect – when the electricity is passed through two connected metals, one will cool and the other gets heated up

  15. Lightweight Nano-Insulation • Uses polymers like polyimide, which are strong and heat resistant, to reinforce silica networks in the aerogel’s structure • Aerogel has been used as insulation in space suits

  16. Nanofabrics • Nanofabrics are textiles engineered with small particles that give ordinary materials advantageous properties such as superhydrophobicity (extreme water resistance). • A fiber that has a width of less than 1000 nanometers(1000 nm or 1 μm) is generally defined as a nanofiber.

  17. Processes and Applications • Sol-gel • Electrospinning • Textile Manufacturing • Drug Delivery • Tissue Engineering

  18. NANOTECHNOLOGY • Disadvantages: -Possible loss of jobs in the traditional farming and manufacturing industry -Crash of certain markets such as oil industry and diamonds -Atomic weapons can now be more accessible and destructive -Inhalation of these minute particles -It is very expensive

  19. Ethical Concerns of Nano-Textiles • Human Health Concerns • Inhalation or exposure can cause health risks • Nanoparticlescan cause cell dysfunction ***Lead to kidney/ bladder disease • Brain damage ***Equivalent to mercury poisoning

  20. Ethical Concerns of Nano- Textiles • Environmental Concerns • Silver can clog sewers • Pollution issues (nano-contamination) • May threaten ecosystem and aquatic life

  21. Ethical Concerns on Nano- Textiles • Economic Concerns • It is expensive • Companies that manufacture cleaning supplies and other commercial clothing products could experience significant decrease in sales

  22. Next step? • Research on existing technologies to further innovations • Active research in the risks of nanotechnology should be promoted • Ethical use by both industrial and commercial use should be carefully monitored and enforced
