WHAT'S that you're wearing? Just a little something you sprayed on this morning?

At a fashion show at London's Imperial College today, particle engineer Paul Luckham and fashion designer Manel Torres are showing the first couture collection made entirely of clothes that came out of a spray can.

The "material" is a mixture of cotton fibres, polymers and a solvent that hardens when it's exposed to air.

Known as "Fabrican", it can be sprayed on, dried and taken off within minutes, even washed and worn again and again.

Mixed with the right chemicals, it can also be broken down and reused.

Mr Torres said by spraying it on the body at different thicknesses, winter and summer apparel can be created.

Using acrylic, linen and wool fibres in the mixture can change the garments' texture.

And it's not just limited to fashion - Mr Torres said Fabrican also had possible medical applications.

"It's a sterilised material coming from an aerosol can, and you can add drugs to it to help a wound heal faster," he said.
