If you're clumsy and constantly spilling food down yourself, or just lazy and don't like washing your clothes, a student has invented the answer to your problems - a T-shirt that is impossible to stain.
The tops can resist any spills and splashes including Coca-Cola, tomato ketchup, mustard, milkshakes, beer, ink and even red wine.
University student Patel from San Francisco made a prototype using a spray-on chemical, but realised it would only last for one wash. He then began looking at ways to incorporate the technology into the fabric.
He created a fabric that has the nanotechnology bonded to the fibres on a microscopic level.
This means they won't irritate the skin.
According to Patel: ‘Most liquid molecules will not be able to touch the fabric because of a microscopic layer of air that forms between the liquid and fabric.
‘This is because the fabric is layered with billions of silica particles. Water based liquids will form a 150 degree sphere and roll right off! As a result, this barrier protects your shirt from potential accidents.’
I wanted to try something different and I had heard about Hydrophobic spray, which is a spray that is completely water resistant.
‘I thought about putting it on a T-shirt but when I was making a prototype after a while I became very light headed and I realised it may not be safe to use.
'I also realised that if I were to put this on clothing, it would wear off after just one wash so it wouldn't be sustainable.
'To make it safe and last longer, I put the technology into the polyester of the T-shirt while it was being made on a nanoscale, molecular level.
"The T-shirts we have now are completely safe and will last for up to 80 washes, so you get around about two year’s worth of wear out of it.'
According to Patel’s Kickstarter page, there are certain steps wearers have to take to make sure the T-shirts stays waterproof.
These include not using fabric softener in a machine wash, no bleaching or washing with colours and no ironing. Patel also advises wearers not to dry clean the shirt.
To reactivate the water repellency, the T-shirt must also be put through a tumble dryer on a low heat at least once every three washes.
Patel said: ‘I started the project a year and a half ago after looking at making smart clothing.
