  1. 1. A BIG FUTURE FOR SMALL SCIENCE : NANOTECHNOLOGY IN TEXTILES Wired And Ready To Wear Textiles Saravana Gouthem.R M.Tech (NANO) 1821310011
  2. 2. Basic Needs Of Every Human Being Food Clothing Shelter
  3. 3. What Is Clothing? Clothing is any covering for the human body. The amount and type of clothing worn depends on the functional considerations such as the need for warmth. In some societies, the minimum amount of clothing covering a person may be acceptable while in others, more clothing is expected.
  4. 4. Evolution of clothes
  5. 5. Evolution of clothes The first clothes were made from natural elements: animal skin and furs, grasses and leaves, and bones and shells.  Clothing was often draped or tied however, simple needles made out of animal bone provide evidence of sewn leather and fur garments from at least 30,000 years ago.
  6. 6. Steps In Manufacture Of Clothes Picking: Removing foreign matter (dirt, insects, leaves, seeds) from the fiber. Early pickers beat the fibers to loosen them and removed debris by hand. Machines used rotating teeth to do the job, producing a thin "lap" ready for carding.
  7. 7. Steps In Manufacture Of Clothes Carding: combines the fibers to align and join them into a loose rope called a "sliver." Hand carders pulled the fibers between wire teeth set in boards. Machines did the same thing with rotating cylinders, where Slivers were combined, twisted, and drawn out into "roving."
  8. 8. Steps In Manufacture Of Clothes Spinning: twist’s and drew out the roving and wound the resulting yarn on a bobbin. A spinning wheel operator drew out the cotton by hand. A series of rollers accomplished this on machines called "throstles" and "spinning mules."
  9. 9. Steps In Manufacture Of Clothes Warping: Gathered yarns from a number of bobbins and wound them close together on a reel or spool. From there they were transferred to a warp beam, which was then mounted on a loom, Warp threads were those that ran lengthwise on the loom.
  10. 10. Steps In Manufacture Of Clothes Weaving: Final stage in making cloth. Crosswise woof threads were interwoven with warp threads on a loom. A 19th century power loom worked essentially like a hand loom, except that its actions were mechanized.
  11. 11. Various Types Of Cloth materials  Cotton  Denim  Wool  Microfiber  Rayon  Polyester  Silk  Velvet  Venise  A Blend  Linen  Nylon  Acrylic  Acetate  Bark Cloth  Cheesecloth  Chiffon  Corduroy  Georgette  Hemp
  12. 12. Nanotechnology In Textiles Nanotechnology can be applied in 'smart textiles', which has a great influence in the field of garment and protective clothing. Nanotechnology play a major role in the following fields of textile: Nano-fibers Nano-finish Nano-dyeing Nano-composites
  13. 13. Nanotechnology In Textiles The use of nanotechnology in the textile industry has increased rapidly due to its unique and valuable properties. Application of nanotechnology economically extend the properties and values of textile processing and products. Use of nanotechnology allows textiles to become multifunctional and produce fabrics with special functions, including antibacterial, UV protection, easy-clean, water- and stain repellent and anti-odour.
  14. 14. Nanotechnology In Textiles Future success of nanotechnology in textile applications lies in areas where new principles will be combined into durable, multifunctional textile systems without compromising the inherent textile properties, including processability, flexibility.

What is wired and ready to wear textiles? Wired and ready to wear textiles are fabrics that are wired to transfer information within a piece of clothing. Right now, you can buy jackets with disc players and controls sewn in, but designers envision e-wear that will heat or cool its wearer, monitor vital signs, and change color on command.
  20. 20. What is wired and ready to wear textiles? Smart clothes and e-textiles offer a second skin to help us understand what goes on under our real skin. They enable us to wear sensors comfortably and unobtrusively to track our physiological signals and our surrounding environmental conditions in real time – anytime, anywhere. They influence the health of patients, the training of athletes, and the safety of fire fighters.
  21. 21. What is wired and ready to wear textiles? Sensors that detect physiological signals may be embedded or integrated directly into a textile (such as part of a yarn that is woven or knitted into the fabric) or they may be applied on top of the fabric, such as in an ink. Since the sensors are part of the garment, they are usually in direct contact with your skin.
