Oak Ridge boffins work out how to dry their clothes

Boffins at Oak Ridge National Laboratory in Tennessee are worried what they will use to dry their clothes when their mothers can’t manage anymore.

A team has come up with a dryer that could make doing laundry much quicker which is five times more energy efficient than most conventional dryers.

It does not matter if you have not done any washing for a couple of months because the drier can do a large load of clothes in about half the time.

Instead of using heat the way most dryers do, the ultrasonic dryer relies on high-frequency vibrations.

Devices called green transducers convert electricity into vibrations, shaking the water from clothes. The scientists say that this method will allow a medium load of laundry to dry in 20 minutes, which is significantly less time than the average 50 minutes it takes in many heat-based machines.

The drying technology also leaves less lint behind than normal dryers do, since the majority of lint is created when the hot air stream blows tiny fibres off of clothing.

Drying clothes without heat also reduces the chance that their colours will fade.

According to the US Department of Energy, the ultrasonic dryer has been in development for the past couple of years.

But now it has recently been “developed into a full-scale press dryer and clothes dryer drum — setting the stage for it to one day go to market through partners like General Electric Appliances”.

Teijin invents stink-free polyester to fight bad BO

Japanese chemical and pharmaceutical outfit Teijin has been working on a kind of anti-bacterial polyester that promises to destroy bad odours.

According to Japanese daily Nikkei, the fabric will still be able to keep armpits from smelling pongy after fifty washes.

It’s aimed at the sporting crowd who tend to sweat a lot. Teijin believes that the polyester will be about 10 percent more expensive than the existing, normal polyester if bought as fabric – but clothes on the high street using the material should sell for about the same price.

The idea is by copying healthy human skin and maintaining slight acidity, it stops unseemly whiffs from clinging. Sweaty skin loses acidity which means bacteria has an easier time multiplying – with a constantly acidic polyester an item of clothing shouldn’t stink. When covered in sweat Teijin’s material, it claims, didn’t give off a funk even after being unwashed for a week.
