Advances in Research

Nanotechnology has profoundly transformed the textile industry by introducing nanoscale materials and devices that enhance fabric functionality, durability and performance. This multidisciplinary field exploits the unique properties of nanomaterials as increased surface area, superior mechanical strength, and quantum effects, to develop smart and functional textiles. This paper reviews the types, mechanisms and textile applications of nanotechnology, offering insights into its transformative potential and the path forward for sustainable innovation. The integration of nanomaterials like silver, zinc oxide and titanium dioxide into fabrics imparts antimicrobial activity, UV protection, water repellency and self-cleaning capabilities. Nanodevices, including nanosensors and nanoelectromechanical systems, have enabled the development of wearable electronics and health-monitoring garments. Nanophotonic structures are also advancing textiles with features like energy harvesting and colour-changing properties. Top-down and bottom-up approaches guide the fabrication of these advanced materials, each offering unique benefits. The top-down approach in nanotechnology involves starting with a bulk material and reducing it to nanoscale dimensions using various mechanical, chemical, or physical processes. The bottom-up approach, in contrast, involves building nanostructures from the atomic or molecular level, assembling them into larger structures through chemical reactions or physical forces. Despite the promise, challenges remain, including health and environmental risks, high production costs, and a lack of regulatory standards. As research advances, sustainable nanotechnology and recyclable smart textiles are emerging as critical future directions. The future of textiles lies in the seamless fusion of functionality and sustainability, guided by interdisciplinary research and robust regulations. With continued innovation, nanotechnology will redefine the role of textiles in healthcare, fashion, defence and environmental applications.
