Nano Technology in Apparel Industry
Nanotechnology has ample potential to enhance the clothing we live, work and play in, but it is not without its drawbacks. From lightweight specialist high-endurance clothing to suits that don’t get wet in the rain, nano-enhanced clothing will become a more and more visible part of our lives in the future.

Nanotechnology is providing clothing manufacturers with whole new dimensions of design to work with. From lightweight specialist high-endurance clothing to suits that don’t get wet in the rain, nano-enhanced clothing will become a more and more visible part of our lives in the future. There are some environmental concerns, as ever, with nanomaterials being included in consumer products, where their disposal route is uncertain, and contamination of wastewater is a potentially huge issue. Not all nanomaterials are as dangerous as silver, however, and further research will only enhance our understanding of how to prevent pollution issues and make nanotechnology safer.
Nanotechnology has ample potential to enhance the clothing we live, work and play in, but it is not without its drawbacks. Nanomaterials face some safety concerns. Fabrics impregnated with silver nanoparticles could shed some of the particles, particularly during wash cycles, introducing the material to the environment where it could interfere with aquatic life cycles or promote antibacterial resistance. Nanoparticles could also be absorbed into the body with unknown consequences. More research is needed to determine safe levels of exposure.
The textile industry has already impacted by nanotechnology. The development in the applications of nanoparticles has been very rapid in past years, particularly in the field of textile finishing. These nano-size materials are able to enhance the physical properties of conventional textiles in areas such as self-cleaning fabrics, water repellence, UV protection, anti-bacterial, anti-static, wrinkle resistance, flame retardant properties of textile materials. Nanofibers also come to occupy the field of textiles and it has tremendous possibility. Research involving nanotechnology to improve performances or to create unprecedented functions of textile materials is flourishing. There is no doubt that in the next few years, nanotechnology will penetrate into every area of the textile industry.
Despite the risks, work on applying nanotechnology to the clothing industry will continue, resulting in innovative products that advance the state of the art in wearable textiles.
