The makers claim that patented pioneering ‘hydrophobic’ technology means the likes of wine and ketchup will simply run off the surface of the machine-washable fabric.
They liken its self-cleaning effect to that of the lotus leaf and say any residues on the 100 per cent cotton material can be removed by just wiping or rinsing off it off with water.
As a result users will be able to wear it for longer between washes, making it greener than regular cotton shirts.
Australian clothing brand Threadsmiths is selling its shirt called ‘The Grind’ for £67 as well as women’s shirts that never get wet.
They say the waterproof effect lasts for about 80 washes and is “reactivated” once tumble-dried.
A spokesman said: “It all started with the obsession to create the perfect t-shirt using an advanced hydrophobic nanotechnology application that makes our fabric water-resistant and stain-repellent.
“Our technology allows dirt and water to simply run off the surface of the fabric.
“What this means for you better clothes that repel liquids, stains and odours.
“It’s also less washing work for you and long term sustainable benefits for the environment.”
It is hoped the fabric could be adapted to create stain-proof tablecloths and aprons for restaurants and cafes as well as being used in the medical sector and hospitals.
