Green nanotechnology in textiles

  1. 2. <ul><li>Swords manufactured in Damascus from 10 th century to as late as 1750 have been found to contain carbon nanotubes (strongest and stiffest material known). </li></ul><ul><li>The sword makers knew nothing about nano-science but were accidentally utilizing nanotechnology. </li></ul>
  2. 3. <ul><li>Nano in greek means dwarf </li></ul><ul><li>One nanometer (nm) is one billionth, or 10 −9 , of a meter. </li></ul><ul><li>A few nanometers wide—motors, robot arms, and even whole computers, far smaller than a cell.  </li></ul>
  3. 5. <ul><li>Easy handling </li></ul><ul><li>Breathability remains </li></ul><ul><li>Suitable for all textiles </li></ul><ul><li>Washing stable up to 40 degree Celsius </li></ul><ul><li>Long lasting sealing of textiles </li></ul><ul><li>Prevent tea, coffee &ketchup stains </li></ul><ul><li>Long lasting production for textiles against water, dirt &grease </li></ul>
  4. 7. <ul><li>Researchers have found that when rats breathed in nanoparticles, the particles settled in the brain and lungs, which led to significant increases in biomarkers for inflammation and stress response and that nanoparticles induce skin aging through oxidative stress in hairless mice. </li></ul>
  5. 9. <ul><li>Producing nanomaterial & products without harming the environment or human health </li></ul><ul><li>Producing nanoproducts that provide solutions to environmental changes </li></ul>
  6. 10. <ul><li>To maximize product performance </li></ul><ul><li>To minimize environmental and health risks associated with textile finishing products </li></ul><ul><li>To improve product recyclability.  </li></ul>
  7. 11. <ul><li>This process for the manufacture of green nanomaterial products eliminates waste, uses ambient temperature and pressure, and uses aqueous solvents only to create products that limit or eliminate the use of harmful chemistries while improving their economy of use by &quot;making every atom count.&quot; </li></ul>
  8. 12. <ul><li>Successful outcomes of the greener programme will enable the production of nano pigments using more sustainable raw material. e.g.) commercially available nanoclays, natural dyes, polymer etc </li></ul>
  9. 13. <ul><li>As a general conclusion, it can be said that green nanotechnology involve a challenging work in textiles industry. It improves the quality of life, environmental friendly commitment &ethical values in nanotechnology. </li></ul>
