Why Does Water Stick to Your Clothes?

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of water adhering to clothing, exploring the underlying physical principles such as surface tension and molecular interactions. Participants are examining the reasons why water does not simply fall off fabrics, considering both theoretical and conceptual aspects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant suggests that surface tension may play a role in keeping water on clothing, questioning why water does not fall off without breaking its shape.
  • Another participant mentions that the ability of a material to get wet is influenced by the orientation of charge groups on the molecules that compose the material, distinguishing between hydrophobic and hydrophilic properties.
  • A participant proposes that magnetic attraction could be responsible for water sticking to clothing, but this is later clarified to involve electric charge interactions instead.
  • It is explained that many molecules have both positive and negative charges, which can lead to interactions with water based on the charges present at the surface of the material.

Areas of Agreement / Disagreement

Participants express differing views on the mechanisms involved in water adhering to clothing, with some focusing on surface tension and others on molecular charge interactions. The discussion remains unresolved regarding the exact nature of these interactions.

Contextual Notes

There are limitations in the explanations provided, particularly regarding the definitions of terms like "orientation of charge groups" and the specifics of how surface tension interacts with fabric materials. Some assumptions about the nature of molecular interactions are not fully explored.

So this question popped up randomly to me for no reason: water seems to stick to clothing, but I was wondering why this is, since to me it seems it should just fall right off the clothes meaning you'd never have to dry them :wink:

I suppose mabye it has to do with surface tension, mabye the water between two fibers has enough surface tension to keep it in place? But still, why wouldn't it fall without breaking its shape?

Thanks for any help :smile: :biggrin:

Surface tension will keep things from getting wet.
For example you can "float" a needle in a glass of water.

If a material will get wet depends on the orientation of charge groups on the molecules that make up the material. (hydrophobic hydrophilic)
Some material will not get wet and you can indeed just shake the water off.
 
So in other words it's magnetic attraction that causes water to stick?

What does "orientation of charge groups mean", I'm a layman :P

Thanks, still trying to figure this whole thing out.

Magnetism is not involved.
It is electric charge, something like walking across the carpet and getting zapped by touching something metal.
Very simply many molecules have an electric charge with + side and a - side.
They can get locked into arrays that predominantly present one charge or the other at the surface.
Water has a predominant exposed charge also.
Equivalent charges repel each other, opposite charges attract.
