Study Notes
Nanotechnology in Textiles
- Nanotechnology has the potential to revolutionize the textile industry by providing permanent solutions to fabric properties that are typically lost after washing or wear.
Nano-Enhanced Textile Properties
- Water Repellence: Nano-Tex technology uses nano-whiskers, which are hydrocarbons much smaller than cotton fibers, to create a water-repellent surface without compromising fabric strength.
- UV Protection: Nano-sized zinc oxide (ZnO) particles provide superior UV-blocking properties compared to organic UV blockers due to their larger surface area and enhanced UV absorption. ZnO nanoparticles are cost-effective, maintain whiteness, and offer UV protection.
- Self-Cleaning Fabrics: Nano-care fabrics, developed by Nanotex, are modified cotton fabrics that resist stains and are self-cleaning. This modification involves altering the cylindrical structure of the cotton fibers.
- Anti-Bacterial Finishes: Metal nanoparticles like silver, titanium dioxide, and zinc oxide impart antibacterial properties to textiles. These nanoparticles catalyze the conversion of oxygen in the air and water into active oxygen, which has a sterilizing effect.
Examples of Nano-Enhanced Textiles
- Sporting Goods: Shark-skin swimsuits, running shoes, tennis racquets, golf balls, and skincare products all utilize nanotechnology to improve performance.
- Body Armor: Kevlar, a strong polymer fiber, is used in bulletproof vests due to its ability to disperse the energy of a bullet over a wide area.
- Lifestyle Applications: Bulletproof vests, clothing that senses surroundings and monitors vital signs, and fabrics with enhanced properties like water repellency, soil resistance, and wrinkle resistance are all examples of lifestyle applications of nanotechnology in textiles.
Future Applications
- Smart Textiles: Textiles with embedded nano-sensors have the potential to monitor vital signs, respond to weather changes, and provide personalized healthcare.
- Energy Storage: Carbon nanotube fibers could potentially be woven into clothing to create energy storage, much like a battery, for powering electronic devices and sensors.
Examples of Commercial Textile Applications
- Nano-Tex: This company has developed spill-resistant fabric coatings that are integrated into the fabric weave, ensuring durability and maintaining the fabric's softness even after repeated washes.
- Clemson University Research: Researchers at Clemson University have developed a self-cleaning coating for clothes using a polymer film mixed with silver nanoparticles.
- Eddie Bauer and Dockers: These companies have implemented Nano-Tex's spill-resistant fabric technology in their clothing lines.
