Study Notes
Nanotechnology in Textiles
- Nanotechnology has real commercial potential for the textile industry.
- Traditional methods for adding properties to fabrics often don't create lasting effects, losing function after washing or wear.
- Nanotechnology can create highly durable fabrics due to nanoparticles' large surface area-to-volume ratio.
- Nanoparticles in fabrics do not impact breathability or comfort.
Composite Fibers
- Nanotechnology plays a crucial role in manufacturing composite fibers.
- Key components include carbon nanofibers and carbon nanoparticles.
- Other important components are clay nanoparticles, metal oxide nanoparticles, carbon nanotubes, and nano-cellular foam structures.
Applications in Apparel
- Nanotechnology-enhanced textiles are used in various industries, including sports, skincare technology, and clothing for extreme environments.
- Treating textiles with nanomaterials improves durability, color, and properties like stain and wrinkle resistance.
- Body warmers utilize phase change materials to respond to temperature changes.
- Nano-silver-treated socks combat infections and odors.
Swimming Suits
- Shark-skin suits, enhanced with nanotechnology, are used in record-breaking Olympic swimming events.
- Nanotech enhances the suit by creating a plasma layer that repels water molecules—reducing drag, boosting speed.
Sporting Goods
- Nanotechnology has enhanced various sporting goods—including running shoes, tennis racquets, golf balls, and skin creams.
- Scientists also use naturally occurring viral nanoparticles to improve nanotechnology in materials.
- A garment that senses its surroundings and interacts with the wearer is an emerging area of interest, using textile-based nanosensors to monitor vital signs and weather conditions.
Lifestyle Applications
- Nanotechnology's earliest commercial applications are seen in textiles and cosmetics.
- Nanotechnology is key in creating bulletproof vests.
- Nanotube fibers are significantly stronger than Kevlar.
Properties of Textile Materials
- Nanotechnology imparts various properties to textiles, including water repellence, soil resistance, wrinkle resistance, antibacterial properties, anti-static properties, UV protection, flame retardation, and improved dye ability.
- Fabrics can also be self-cleaning.
Water Repellence
- Nano-tex creates nano-whiskers that make fabrics repel water, maintaining strength and creating a 'peach fuzz' effect.
UV Protective Finishes
- Nanotechnology protects wearers from UV radiation (wavelengths from 150 to 400nm).
- Metal oxides (ZnO) are more stable as UV-blockers.
- ZnO nanoparticles are better than nano-silver in terms of cost, whiteness, and UV-blocking effectiveness.
- Fabric treatment with UV absorbers protects against harmful UV rays.
Self-Cleaning Fabrics
- A self-cleaning cotton fabric called Nanocare is available and popular.
- Nano-silver, titanium dioxide, and zinc oxide are elements used for antibacterial properties.
- Metallic ions enhance sterilization.
Clothes Make the Man
- Historical context is provided about fabric's protection.
- Kevlar, a strong DuPont polymer fiber, is used in bulletproof vests. Energy is dispersed to prevent penetration.
- Interlaced Kevlar fibers distribute bullet impact, allowing force to be absorbed throughout the cloth instead of concentrated at a single point of impact.
Kevlar Nanofibers
- Kevlar aramid nanofibers (KANFs) are a nanoscale version of poly(paraphenylene terephthalamide).
- These fibers have unique properties like electrical conductivity, flexibility, mechanical strength.
Spider Silk and Other Fabrics
- Nexia Biotechnologies utilizes genetically engineered goats to produce spider silk, creating a material far stronger than steel.
- Carbon nanotubes increase strength, and are useful in products like bulletproof vests.
- Eddie Bauer and Dockers utilize nanotechnology to create stain-resistant and durable textiles.
Other Technologies
- Quick-drying fabrics remove moisture to provide a cooler wearing experience, combining synthetic and cotton-like features.
- Clemson University, using silver nanoparticles, created self-cleaning fabrics that repel dirt with water.
- Additional outdoor items can be designed using this technology such as convertible car tops or lawn furniture. Less detergent can also be used saving money and benefiting the environment.
