- Nanofibres
- what are they?
- a polymer membrane formed by electro- spinning. this polymer is dissolved in a solution which evaporates to form the fibre.
- advantages
- high surface-area-to-volume ratio
- mass production is easily achievable- making it suitable for industrial production and commercial applications
- wide variety of polymers and materials can be used to form nano fibres
- ease of fibre functionalisation- can be achieved by blending the polymer solution either pre or post spinning.
- ease of material combination- different materials can be easily mixed together for spinning into fibres
- relatively low start up cost
- variety of nanofibrious structures can be constructed
- high surface-area-to-volume ratio
- medical textiles
- wound healing- nano fibres allow liquids and gasses to pass through dressing while still keeping bacterial away.
- anti-adhesion properties- post-surgical tissue adhesion of internal organs. nano fibres have the ability to dissolve into the body without causing toxicity.
- nano-fibres used for tissue re-engineering are biodegradable.
- tissue engineering- effective scaffold as most human organs are made up of nano fibre-like structures. they can be used to create a 3D model so cells can grow and attach to it.
- wound healing- nano fibres allow liquids and gasses to pass through dressing while still keeping bacterial away.
- sportswear
- popular to replace breathable membranes in high-end performance sportswear. potential to create a waterproof fabric with a level of breathability
- nano socks treated with silver particles to act against infection and odour
- nanofibre shark ski. used for swimwear. incorporates plasma layer enhanced by nano-technology to repel water and help the user glide through the water
- nano sensors provide personalised healthcare system- monitoring vital signs as you run up a hill or respond to changes in the weather.

- carbon nanofibres- increase thermal comfort of garments. useful for skiwear. high tensile strength and insulating properties combined with light weigh properties make it comfortable and protective.

- fashion industry
- stain-repellent and wrinkle-resistant threads are woven into fabrics
- silver can be added in the form of nanoparticleson the surface to reduce bacterial growth
- UV nano absorbers- ensure that textiles can deflect the harmful ultraviolet rays of the sun. reduces UV exposure and protects skin fro potential damage
- self-cleaning fabrics- created by wrapping original fibre in minute whiskers using nanotechniques. the whiskers trap air creating a hydrophobic surface when in contact with water. allows dirt to be captured in beds of water which then roll of the surface

- military
- protection against gas and chemicals- nano fibres sensitive to chemicals and will absorb and decompose the chemical agents.
- nano fibres can be used as water filters (also applicable to Geotextiles)
- nano fibres can switch from breathable state to protective in response to environmental threats. In protective state the material will block chemical threat while maintaining breathability level.
- nanotube fibres can be used to make a material 17 times tougher than Kevlar
- silver nanoparticlesused to minimise bacterial growth and decrease odour
- nano fibres can switch from breathable state to protective in response to environmental threats. In protective state the material will block chemical threat while maintaining breathability level.
