Nano finishes can provide various functional benefits to textiles. Nanoparticles like whiskers, nets, and wraps can be applied to fibers at the molecular level to alter their properties, unlike traditional resin finishes. For example, nano whiskers can make fabrics water and stain resistant while remaining breathable. Nano nets can give synthetic fibers properties of natural fibers like linen. Nano wraps can enhance fabric strength and durability after repeated washing. Specific nanoparticles like zinc oxide and titanium dioxide can provide UV protection and antibacterial properties. Overall, nano finishes allow adding value through functional improvements like moisture wicking and durability without compromising softness and comfort.

2. What is Nano Technology? Scientific and technological advances that rely on the properties of materials at a very, very small scale. Involves lots of complex concepts that are little difficult to understood. “ The design, characterization, production and application of structures, devices and systems by controlling shape and size of building blocks at the nanometer scale.” Nanoscale Region of greatest interest is 0.2-100 nanometres (nm). 1 m = 1000 million nm, or 1 nm = 10-9 m

6. Textile Applications of Nano Technology... FUNCTIONAL water repellent PROTECTION UV absorption DURABILITY color fastness DURABILITY abrasion SAFETY fire retardancy FUNCTIONAL HYGIENE Anti-microbial FUNCTIONAL PROTECTION Controlled release of additives Nano Treated Textile FUNCTIONAL PROTECTION self-cleaning

8. Whiskers Spine Hooks Whiskers Fiber The whiskers get hooked on the fibers to alter the fabric property.

9. Nano Whiskers can make the fabric stain & water resistant… Nano whiskers can keep the fabric breathable too unlike resins finishes!

11. Net Three Dimensional Molecular Nano Net covers the core fiber Completely.

12. Nano Net can inject linen property into a synthetic fiber… How the original fiber is altered! Absorbency @ linen in a polyester!

14. Wrap Nano sheet wraps the fiber completely to cover it & alter its property.

15. Nano wraps can enhance the fabric robustness… Normal fabric trouser with out nano wrap on the fibers after 50 washes! Trouser made up fabric with nano wrap fibers after 50 washes!
