Would laundry be any drier if it's spin dry in a vacuum?

Question

Just a hypothetical question hope that someone could come out with a sensible answer.

Answer 1

I think....probably, but there would be wrinkles.....

Answer 2

The short answer is yes, there will be less water, but it is very difficult to remove all water. Laundry is composed of organic fibres that tend to trap water on a mesoscopic scale and to physisorb and chemisorb water on a molecular level. While a vacuum will remove virtually all of the free water, you can assume that every surface will have at least a monolayer of water remaining. The surface area of fabrics is enormous, so a lot of water would be retained. In vacuum technology it is called a virtual leak. It is possible to supply radiant energy (photons) to overcome the binding energy of water molecules, but this can also decompose the fabric. In a vacuum chamber, an ionization pressure gauge is used to measure the residual pressure. In my experience, the pressure gauge for your laundry would be stuck at 1E-5 Torr or worse for weeks or months. (A clean vacuum chamber with a good diffusion pump will achieve 1e-6 Torr in a few hours.)

Answer 3

Yes. Not only would the heat expel the moisture at one atmosphere of pressure, as now, and blow the humid air out the vent, but but the moisture would literally disappear into the vacuum.

Answer 4

Let's take the word vacuum. It is a space without air. Without air you cannot heat or cool. Hope this helps

Answer 5

True vacuum... not possible. The water molecules need to evaporate somewhere, but there is no air in a vacuum... so they have no where to go!

Answer 6

yes, water would boil off in a vacuum

Answer 7

Ummm, no, because it could not be WET in a vacuum!

Answer 8

You tell me.
