Nanotechnology in Fabrics

How can nanotechnology improve fabric?

Making composite fabric with nano-sized particles or fibers allows improvement of fabric properties without a significant increase in weight, thickness, or stiffness as might have been the case with previously-used techniques. For example incorporating nano-whiskers into fabric used to make pants produces a lightweight water and stain repellent material.

Fabric: Current Nanotechnology Applications

Nanowhiskers that cause water to bead up, making the fabric water and stain resistant.

Silver nanoparticles in fabric that kills bacteria making clothing odor- resistant.
Nanopores providing superior insulation for shoe inserts in cold weather.
Nanoparticles that provide a "lotus plant" effect for fabric used awnings and other material left out in the weather, causing dirt to rinse off in the rain.

Fabric: Nanotechnology Applications under Development

Lightweight bulletproof fabric using nanotubes:

Solar cell fabric using Konarka’s Power Fiber^TM

Clothing protective against hazardous chemicals using an honeycomb of polyurethane nanofibers
