Nanotechnology is an emerging multidisciplinary technology that is typically viewed as an industrial revolution. Materials with lengths between one and one hundred nanometers are the focus of nanotechnology. The basic idea behind nanotechnology is that materials undergo significant changes in properties as their dimensions are reduced to the nanoscale scale. The textile industry is now aware of the potential of nanotechnology. It is employed to create the necessary textile qualities, such as antibacterial textiles qualities, fire resistance, water resistance, enhanced fabric durability, softness, exceptional surface structure, high tensile strength, and so on.

Sportswear and spacesuits are now among the quickly growing applications of nanotechnology. The most well-known sharkskin suits worldwide are those made with enhanced plasma layer technology, which facilitates trouble-free swimming. Because they are used in surgical gowns and gloves, nanotextiles are also widely used in the healthcare sector.

The Rise of Nanotechnology in Fashion

Fashion designers are always attempting to update the apparel sector, and nanotechnology has given it a fresh perspective. By employing nanoparticles to generate waterproof, microbicidal, UV-blocking, or antistatic textiles without drastically altering their thickness or weight, nanotechnology has opened up a new market for functional fashion.  Without the use of dyes, nanotechnology in fashion can regulate color in a customizable manner. Ag nanoparticles, for instance, can be utilized to produce a gleaming metallic yellow hue. The market for textiles based on nanotechnology, or nanotextiles, is rapidly growing.

Additionally, smart fabrics are pushing the Nanotechnology in fashion industry. Smart textiles are able to detect the movement of their users. Researchers create a cozy, form-fitting fabric and enhanced fabric durability that can detect the movements of its wearer, such as running, leaping, and strolling.

And we must not overlook "Moisture-wicking technology" while talking about smart textiles. They wick away perspiration to keep the body cool and dry during an exercise, which is why they are most frequently linked to sportswear. The fact that sportswear has given Moisture-wicking technology a platform to spread and become a more widely used smart textiles is undeniable; but, the specialized garment industry can and will also Moisture-wicking technology.

Key Applications of Nanotechnology in Textiles Material

In the textile business, the characteristics of textile materials made using nanotechnology are crucial. A brief discussion is given of the use of several textile nanomaterials properties:

• Water Repellence: Because the nanowhisker is 1100 times smaller than a hydrocarbon and a typical cotton fiber, it gives the fabric water-repellent qualities. The addition of nanowhiskers to the fabric produces a peach fuzz look without reducing the cotton's strength. The water remains on top of the whiskers and above the advanced fabrics surface because the gap between the whiskers on the fabric is longer than the water molecule but less than a normal drop of water. Even under pressure, liquid can still flow through the cloth.

• UV Protection: The garment's primary purposes are to shield the user from the elements and the sun's damaging rays. Commonly used UV-blockers ZnO and TiO2 offer superior protection against UV rays because they are more effective at absorbing and dispersing UV radiation than traditional size.

• Antimicrobial: To give textiles antibacterial textiles qualities, a variety of antimicrobial chemicals are utilized, including triclosan, TiO2, ZnO, and nano-sized silver. By using nanoparticles, the antibacterial impact can be reduced because there are more particles per unit area.

• Antistatic: To lessen or get rid of static electricity brought on by the triboelectric effect, an antistatic chemical is frequently utilized.  Because they are electrically conductive, some nanoparticles, including TiO2, ZnO, and ATO, have anti-static properties.

• Use in the Apparel Industry: Nanotechnology-enhanced textiles are already in use in a number of industries, such as cosmetics, sports, space technology, apparel, and materials technology, which are employed to improve protection in harsh conditions. Nanotechnology is also used to improve bulletproof vests, skin treatments, medical gloves, tennis racquets, golf balls, jogging shoes, and swimming suits.

• Global Status of Nanotechnology in Textile: Several nations, including the United States, China, Canada, Germany, and India, are pursuing sustainable fashion innovations in textile nanotechnology. Nanotechnology is constantly releasing new designs in the clothing industry. For instance, a Teijin Group textile manufacturer debuted a new range of sportswear and other wearable technology in January 2019. With an annual growth rate of 6.6%, the worldwide nanotechnology apparel market increased from $4.24 billion in 2020 to $6.3 billion in 2021. The influence of COVID-19 has caused a little slowdown in its growth, but by 2025, it is anticipated to reach 25%.

Challenges and Considerations in Nanotechnology for Fashion

In order to develop nanotechnology in fashion safely and responsibly, a number of issues and challenges must be resolved:

• Toxicology: The accumulation of nanoparticles in different organs might cause harm. Studies have revealed that nanoparticles may build up in animal brains, lungs, and nasal canals, which raises questions about how they might affect human health.

• Long-term safety: Because nanoparticles may have harmful impacts on both people and the environment, there are worries regarding their long-term safety. According to studies, nanoparticles may gradually build up in the body and cause a number of health problems.

• Commercialization: It takes a lot of money and experience to scale up nanotechnology for mass manufacturing. There are obstacles to overcome while moving from laboratory-scale production to industrial-scale manufacture.

• Resource availability: Although there are some reservations about the supply of resources needed to produce textile nanomaterials, there are plenty of vital minerals on Earth.  However, careful resource management can be necessary when manufacturing is scaled up.

• Regulation: The laws governing nanotechnology are still being developed, but as the field advances, new rules must be added frequently to maintain safety and openness.

• Impact on the environment: Because of their small size, nanoparticles may enter the environment deeply, which raises questions about how they will behave and perhaps cause chemical reactions when they come into contact with other particles. One major obstacle is the paucity of thorough study on these topics.

• Health consequences: Inhaled nanoparticles may cause cardiac issues and lung inflammation, among other negative health effects. Addressing health issues associated with nanotechnology requires an understanding of how nanoparticles interact with living things and their possible long-term health effects.

• Safety talk: To ensure responsible development of nanotechnologies, the safety and dangers of nanoparticles must be discussed. Resolving nanoparticle-related safety, health, and environmental issues is essential to their long-term application.

The Future of Nanotechnology in Fashion

Although we cannot predict exactly what the nanotechnology in fashion of the future will look like, many of us anticipate that garments in a few years will have significantly improved functionality, utilizing technology to produce safer and cleaner materials. Using nanotechnology in fashion to eliminate dirt or kill germs is one technique to accomplish these objectives.

The use of nanotechnology in fashion industry is not a recent development. Many apparel firms began adding silver nanoparticles to their goods in the middle of the 2000s. Because silver nanoparticles are antibacterial textiles, they eliminate the microorganisms that produce unpleasant smells. The finished clothing requires fewer washings as these nanoparticles are added to the advanced fabrics to stop odor. These nano-infused products are still in demand today and come in a variety of styles, from t-shirts to socks.

Beyond antibacterial textiles nanoparticles, the field of nano-fabrics is producing a great deal of innovative technologies. Self-cleaning clothing, water-repellent textiles, and apparel that may lessen odors by chemically altering the chemicals that create unpleasant scents are further desirable clothing qualities that might be accomplished with nanotechnology.

There are already some of these more futuristic-sounding functions under development. Recently, smart textiles coated with nanoparticles of copper and silver have been created that, when exposed to sunlight, may break down organic things like food and dirt. By absorbing visible light, these textile nanomaterials create "hot" electrons with high energy that can decompose nearby organic compounds.

The lotus leaf's hydrophobicity also allows it to be self-cleaning; dirt that initially adheres to the leaf surface is frequently removed by water droplets that roll off the plant. Scientists are trying to make synthetic superhydrophobic textiles by taking advantage of the lotus effect.
