What is NANO ? • NANO – “nanos” in Greek means “Dwarf”, a size scale (One billionth) • NANOMETER – One billionth of a meter

What is Nanotechnology ? • NANOTECHNOLOGY - Professor Norio Taniguchi of Tokyo Science University coined this term in 1974. • The design, characterization, production and application of structures, devices and systems by controlling shape and size at nanometer scale

Nano-encapsulated Mosquito Repellent Particles image under SEM

Advantages 1. Protection to human life Anti-bacterial, Anti-Mosquito functions, UV protection 2. Apply on existing equipments Padding, curing machine in Dyeing and Printing factory Washing, drying machine in Garment washing factory 3. Environmentally friendly Most of the nanometer materials are non-toxic and bio-degradable 4. Minimizing the usage of chemistries Detergent 5. Retain fabric softness and breathability

Application on Fabric – Padding machine

Breathable Properties & Better Hand-Feel Ø Nano-Particles are bonded directly to the fiber surface the textiles gain special characteristics as: ü Fabric retains breathable properties ü Enhanced comfort and better hand-feel Nano particles bonded on fiber under SEM

Green Technology for the Earth’s Resources Ø There are 2 classes of Savings: ü Direct Savings of Resources ü Indirect Savings of Resources as: q Shorten the washing time (less energy and water consumption) q Fewer number of washings for a given time (less energy, water and detergent consumption) q Low water temperature for washing (smaller energy consumption) U care W care about our Earth

Conclusions Ø High Tensile Strength ü High Durability ü Long Lasting Results Ø Physically Stable ü ü ü Wide Range of Applications Multifunctional Characteristics Simple & Quick Application Ø Chemically Reactive With Free Radicals ü Self Cleaning & Antibacterial ü Green Technology Hydrophobic materials, Liquid Repellency Ø Superconducting Properties ü ü ü Smart Fabrics E-Textiles Wearable Electronics
