1 NANOTECHNOLOGY IN CLOTHING AND TEXTILES

2 KEY TERMS MEMS – three dimensional objects that perform a mechanical function, whose dimensions are between 1 to 100 micrometers Nanoparticle – a particle of material at the nanoscale Nanotechnology – a material or structure purposefully manufactured with dimensions between 1 and 100 nanometers to leverage the unique properties it has at that size

3 Nanosphere – a round particle with nanoscale proportions Nanowhiskers - are ten nanometers long, made out of carbon, and designed to be flexible Nanofiber - are defined as fibers with diameters less than 1000 nm nanometers. They can be produced by interfacial polymerization and electrospinningfibersnanometers interfacial polymerizationelectrospinning

4 Electrospinning – uses an electrical charge to spin fibers into a nonwoven pattern Polymer - is a large molecule (macromolecule) composed of repeating structural units; encompasses a large class of natural and synthetic materials with a wide variety of properties.moleculemacromoleculestructural units

9 Nanotechnology in textiles has been around since humans began dyeing fibers and fabrics to impart color, which dates back to 2600 BC in China Chemists have used surface chemistries not only to color textiles, but also to impart many different properties to fibers and fabrics Today, coatings and dyes are commonplace for textiles to market products using a nanotechnology spin

10 The world of consumer textiles has been changed by nanotechnology. Manufacturers have created stain-resistant or moisture- wicking fabrics by applying a chemical finish containing nanoparticles to cloth.

11 WHY NANOTECHNOLOGY? Emotional clothing Odor free clothing Stain repellant clothing Clothing that changes colors UV protection in clothing from zinc-oxide nano-particles Clothing to prevent colds and the flu Clothing that does not need to be washed

12 FABRICATION OF NANOFIBERS Fibers with diameters of several hundred nanometers or less Nanofibers fabrication is electrospinning Fibers are absorbent, breathable, and/or water- repellent

13 SURFACE MODIFICATION Used to impart unique properties to fibers and fabrics Applications range from water and stain repellency, wrinkle resistance, and flame retardation /markets__applications/applications_pour_le_textile_et_le_cuir

14 NANOPARTICLE COMPOSITE FIBERS Incorporation of nanoparticles, such as silver particles and carbon nanotubes, can be used to create fibers that are antimicrobial or have increased strength of electrical conductivity 6750/9/34/figure/F8?highres=y

15 Military uses socks that can be worn for two weeks between washing Military has invested in fabrics reinforced with nanofibers for high performance, lightweight tents, and awnings that can better endure heavy wear and tear \ 87.html

16 Hunting clothes use nanotechnology to cover scent

17 Face masks have been created that when exposed to light, kills viruses and bactiera

18 NANO-TEX Nanowhiskers allows fabric to breathe without changing how the fabric feels

19 SMART TEXTILES 1980s – clothing that changed colors; pink when cool; blue when warm 1990s – swimmers body suit to streamline swimmers movement and reduce water on the swimmers back electronics embedded within clothing; the cooling jacket which prevents shivering; clothing to monitor heat rate

20 NANO-TEX (FIBER TREATMENTS) Coolest Comfort – moisture drawn from the skin helps body temperature balance Resist Spills – liquid beads up and simply rolls off fabric or easily wipes off Repels and Releases Stains – liquids roll of and stains wash out easily Resist Static – eliminates static in synthetic fabrics

21 TORAY INDUSTRIES Offers a variety of fabric treatments using a nanoscale processing technique called NanoMatrix Example: Tapguard which is soil resistant, water repellant, and oil repellant; used for uniforms in the food industry

22 INKMAX Developed nano-fine adhesive polymers, 70 nanometers thick, that are found on cotton fabric. This allows for ink jet printing with no water. detail/xJQxmEnAMEhQJQJEnxmyGxLE/Cotton-Poplin- Spandex-Fabric.html

23 ANTI-BACTERIAL Silver nanoparticles and titanium dioxide are being added to fibers to provide deodorizing, anti-bacterial, and soil- resistant properties

24 Japan Exlan offers a fiber called selfclear, which relies on nanoparticles of titanium oxide ns.html

25 The TioTio air catalyst from Sunward Shokai provides yarn with a deodorizing, antibacterial treatment and relies on the use of titanium oxide. cross-yarn.html

26 NEW FIBERS Greenyarn – based on nano-particles of bamboo charcoal is antimicrobial and deodorizing properties Japan Wool Textile Nikke Miracle products -Wel Warm – moisture-absorbing and heat generating properties -Bambool – wool and bamboo fibers that are anitbacterial, deoderant, and moisture absorbent -CoolTwist – wool and yarn infused with ceramic nanopowder to block UV rays

27 IMPACT RESISTANCE Liquid Armor (shear thickening fluid) – its nanoparticle based coating material allows fabric to remain flexible, but upon impact becomes hard. Used for body armor vests, helmets, and gloves.

28 d30 has a product made of intelligent molecules that are incorporated in sports gear. It is a thin, flexible sheet like bubble wrap. Viscose fluid and polymer lock upon impact creating a rigid pad.

29 ATHLETIC APPAREL New Balance created the Skye Crop sports bra that makes use of nano channel yarn as part of its Lightning Dry Extreme Liner profile-crop-sports-bra.html
