    Study Notes

    Nanotechnology in Textiles

    • Nanotechnology enhances textiles by providing durability, breathability and softness while maintaining aesthetic appeal.
    • Common applications of nanotechnology in textiles include:
      • Sporting goods: swimming suits with water-repellent layers, running shoes, tennis racquets, golf balls, and skin creams.
      • Extreme environments: clothing and materials for better protection in harsh conditions.
      • Personal health care: textiles with nano-sensors for monitoring vital signs.
      • Lifestyles: bulletproof vests and stain-resistant fabrics with nanotechnology coatings.

    Properties Improved by Nanotechnology in Textiles

    • Water repellence: Nano-whiskers create a peach fuzz effect on fabrics for water-repellent properties.
    • UV protection: Metal oxides such as ZnO enhance UV-blocking properties due to their large surface areas and strong absorption in the UV region.
    • Self-cleaning fabrics: Nano-care fabrics are modified with cylindrical structures for self-cleaning properties.
    • Antibacterial finishes: Nano-sized silver, titanium dioxide, and zinc oxide are used to impart antibacterial properties by turning oxygen into active oxygen through catalysis.

    Body Armour

    • Kevlar: a strong polymer fiber that is 5 times stronger than steel.
    • Kevlar aramid nano-fibers (KANFs) offer a combination of electrical conductivity, flexibility, mechanical robustness, physical stability, and resistance to solvents.
    • Spider silk is 20 times stronger than steel and is produced by genetically engineered goats.
    • Carbon nanotubes are 100 times stronger than steel and can be used in bulletproof vests, energy storage, and monitoring human vital signs.

    Clothing with Nanotech Enhancements

    • Spill-resistant fabric nanotech coats fibers with polymers for stain resistance.
    • Quick-drying cloth uses nanotechnology to wick away moisture and keep the wearer cool.
    • Synthetic fibers that mimic cotton are engineered for color fastness, durability, wrinkle resistance, and softness.
    • Self-cleaning coatings for clothes are made with silver nanoparticles and polymer films.
