N ANO technology has been a core of many research work for the past fifty years. Applications of nanotechnology in textiles field have increased such products value, and made these textiles as a very important part of smart inventions. Durability, comfortability, hygienic properties, UV protection, energy saving and many other properties have been achieved through using the application of nanoparticles in textiles weather through coating or encapsulation or other methods. (PANI)/polyacrylonitrile (PAN) nanofibers, silver nanoparticles, single/multi-walled-nano carbon tubes (SWCNT/MWCNT) and Ag, Au and Cu nanoparticles have been used in smart and smart wearable textiles such as stretchable textiles and wearable solar textiles, triboelectric nanogenerator and one-piece self-power/self-charging power textiles. Smart wearable textiles are a result of the combination between nanotechnology and smart textiles which will be the next trend of textiles research.
