- 2. WHAT IS NANOTECHNOLOGY •the termnano in nanotechnology comes from a Greek word “nanos” which mean ‘dwarf’. (abnormally small) •one nanometer is one billionth of a meter or 10-9meters. one nanometer is about 100000 times smaller than the diameter of human hair. •Nanotechnology is design characterization production and application structures ,devices and systems by controlling shape and size at the nano scale
- 3. Nanotechnology is definedas the study and use of structures between 1 nanometer and 100 nanometers in size. To give you an idea of how small that is, it would take eight hundred 100 nanometer particles side by side to match the width of a human hair. WHAT IS NANOTECHNOLOGY
- 4. WHY NANOTECHNOLOGY IN TEXTILE ? Itcan define nanotechnology in textile as the understanding, manipulation, and control of matter at the nano level, such that the physical, chemical, and biological properties of the materials (individual atoms, molecules, and bulk matter) can be engineered, synthesized, and altered to develop the next generation of improved materials, devices, structures, and systems. It is used to develop desired textile characteristics, such as high tensile strength, unique surface structure, soft hand, durability, water repellency, fire retardancy, antimicrobial properties, etc

- 11. • Water repellentplant gives us the idea to make water repellent fabric. Complex molecule called polymer is coated over normal fabric and heated until the polymer bonded with the fabric. This coating implants Nano whiskers over the fabric so liquid cannot touch it. • Nano whiskers can make the fabrics stain and water repellent

- 15. Nano Finishes Nanofinished textiles are those that a paly a Nano scale property added after the base textile has been fabricated. This includes post-manufacture treatments and coatings to apply nanomaterial's or create nanostructured surfaces on fiber media.
- 16. Present Scenario InTextile Finishing Innovation Luke worm in spite of fast changing fashion cycle . Technical advancement and art of finishing technology is quit old Fabric and garment finishing basically by covering the texture of the fabric by resins Common problems like spills ,strains ,wear and tear remains and salts. Lack of innovation to texturize the fabric on the molecular level.

- 18. Clay Nano Particles-Uv Protection Clay nano particles (e.g. clay nano particles of montmoriblonite) or nano flakes are used for the purpose. These types of substances contain hydrogen aluminosilicates, having difference in the chemical composition & crystal structures. The clay nano particles have a property of locking UV light. It also has electrical, chemical & heat resistance. Hence the UV rays can be removed by the fabric having a finish of clay nano particles.
- 19. The antimony pentoxide nano particles - Flame retardant finishing The antimony pent oxide nano particles along with Halogenated flame-retardants are used for the flame retardant finishing. The antimony has a characteristic of flame retardency. Hence the presence of antimony particles along with halogenated flame retardant in the fabric increases a flame retardant property of the fabric.
- 20. Tio₂ Nano Particals-Photo Catalytic Self-cleaning The TiO₂ is a recognized catalytic compound. it shows it`s catalytic property by the absorption of a photon and jumped to the conduction band from the valance band. That is able to remove the organic pollutants and xenobiotics from the textile materials. Hence by treating the fabric or yarn by the particles, the fabric or yarn can be brought into photo catalytic self cleaning property
- 21. Silver Nano Particles– Anti Microbial It is an old concept that “silver” molecules have a power to resist bacteria and microorganism. Hence the food, water, any other substance have great weakness to bacteria or microorganism were kept in the utensils of silver metal. This antibacterial property of silver particles has been proved scientifically. This finishing procedure is carried out by the encapsulation of the silver compounds i.e. the nano particles of silver are encapsulated in the fiber reactive polymer.
