Discussion Overview

The discussion centers on the phenomenon of static cling in relation to cotton towels in a dryer, exploring why static cling does not develop when drying a load consisting solely of this material.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant notes that static cling does not develop with cotton towels in the dryer and seeks an explanation.
  • Another participant explains static cling as the result of electrostatic forces between objects that acquire opposite charges through contact, emphasizing that the likelihood of charge separation depends on the materials involved.
  • A question is raised about the specific processes occurring in a clothes dryer.
  • It is stated that rubbing together of materials in the dryer typically leads to static cling.
  • A participant asserts that static cling should occur, but another counters that it only happens when dissimilar materials are present, referencing the earlier explanation about charge separation.

Areas of Agreement / Disagreement

Participants express differing views on whether static cling should occur with cotton towels, with some arguing that it should and others suggesting that it does not due to the similarity of the material.

Contextual Notes

The discussion includes assumptions about the behavior of materials and their charge separation properties, which may not be fully explored or agreed upon.

Circuit
I have read in a book that "static cling" does not develop when a clothes dryer is used to dry a load consisting only of cotton towels. I don't know why. Can anybody tell me?
 
Physics news on Phys.org
Static cling is a common term for the attractive electrostatic force between two objects that have opposite types of electrical charge. Two objects will get oppositely charged when they are rubbed together. THis action actually causes one of the objects to pull a few electrons off the other object. For example, silk will pull electrons off of glass, making the glass positiely charged and the silk negatively charged. Rubber will pull electrons off of wool making the wool positively charged, etc.

Whether an object will pull electons off another object or get electrons pulled off it depends on the configuration of the molecules. All materials can be ranked in an order of increasing likeliness to lose electrons. The charge separation that occurs requires that the two objects be from different parts of the list (one higher, one lower) otherwise each of the two objects will be equally as likely to lose electrons, and therefore each would be just as likely to gain them. There would be no net gain or loss of electrons for either object.

If the two objects are the same material then they will be at exactly the same location on the list, of course. The reason for different materials being at different locations on the list is a much harder question to answer

Things rub together.
 
Then there should be a "static cling".

There is, when the things in the dryer are dissimilar. Did you read and understand the first reply?
