Students make waterproof T-shirts

Student Aamir Patel (20) from De Anza College in San Francisco (USA) has created a special T-shirt: Waterproof, including 'hard to find' liquids such as soft drinks, tomato sauce, wine.

If you are a backyard worker, spilling food or lazy clothes do not want to wash your clothes, a shirt that does not leave traces of American students can be the solution.

T-shirt that does not stick to fresh water

The shirt can withstand any liquid including soft drink, sour sauce, mustard, beer, milk, fruit juice, writing ink, even wines made of synthetic fibers combined with chemicals. Waterproof. However, this T-shirt does not make you feel any different compared to other products are sold in the shop.

At first, Patel students only use a casual shirt, then buy the spray chemicals but he realized the shirt would lose the waterproof effect after a wash. Like many others, I was fascinated by the waterproof sprays spread on Youtube so I bought a box to spray the shirt. After a few hours, I felt dizzy, breathless. I flipped the bottle back and shocked when I read the product warning label that could cause cancer and other serious side effects. '

Not only does the damage to health, Patel also found the waterproof coat spray more troublesome when the fabric hard and stick together after washing. Soon after, the student started to make his own waterproof vest. The T-shirt is made of silicon with billions of silica grains bonded to the yarn. The liquid that comes into contact with the shirt becomes a ball and rolls away.

Patel also claimed the shirt was soft, safe and easy to wash, antibacterial, sweat-free and moldy. Male students also said that the silicon T-shirt can withstand 80 washings. It is scheduled to be available in May 2014 and sell for $ 30.
