If you are clumsy and constantly spilling food down yourself , or just lazy and do not like washing your clothes , a student has invented the answer to your problems - a T - shirt that impossible stain .
The tops can withstand any spills and splashes including Coca - Cola , tomato ketchup , mustard , milkshakes , beer , ink and even red wine .
Clothing is made from polyester , which has been infused with a combination of chemicals that make it resistant to water .
Despite this , the T - shirt is said to feel ' no different from any other items you find in a clothing store . "
Patel University student from San Francisco to make a prototype using a spray - on chemicals , but realized it only takes one for the wash . Then he started looking at ways to integrate technology into the fabric .
He created a nanotechnology fabric bonded to fibers on a microscopic level .
This means they will not irritate the skin .
According to Patel : " Most of the liquid molecules are not able to handle the fabric for a microscopic layer of air that form between the liquid and fabric .
' This is because the fabric is layered with billions of silica particles . Water based liquid generates a 150 degree sphere and roll right off ! As a result , this barrier protects your shirt from potential accidents . '
After testing its way , the students created a business page about the invention , named Silic , the crowdfunding website Kickstarter .
That exceeded his target of around $ 20,000 ( £ 12,250 ) , before the close of the campaign on January 26 . The shirts are expected to be on sale online from May and cost around £ 30.
According to the Kickstarter page Patel is , there are some steps that wearers need to do to make sure that the T - shirt remains waterproof .
Along with it not using conditioner on a machine wash , no bleach or washing with colors and no ironing . Patel also advises wearers not to dry clean the shirt .
To reactivate the water repellency , the T - shirt should also be placed in 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 .
' I wanted to try something different and I heard about the spray Hydrophobic , a spray that completely water resistant .
' I thought about putting it on a T - shirt but when I was doing the prototype after a while I became very light headed and I realized it may not be safe to use .
" I also realized that if I were to put it on clothing , it would wear off after just one wash so it would not be sustainable .
' To make it safer and longer lasting , I put the technology in polyester T - shirt as it is done on a nanoscale , molecular level .
" The T - shirt now we are completely safe and will last up to 80 washes , so you get around about two years 'worth of wear out of it . '
