It also occurs when some clothes stick to the skin when they are worn. It is usually caused from drying or wearing synthetic materials that collect electrical charges. This problem can be reduced by treating the materials or eliminating the static electricity that causes it.

This lesson will answer those questions. Useful tool: Units Conversion The cause of static cling is that the materials involved become charged with static electricity. When clothes made of certain fibers—typically, synthetic materials like polyester—rub against each other or against dry skin to create static electricity. Such clothes will cling together when taken out of the dryer. Besides rubbing together, the water is removed from the material, as well as the surrounding air. Static electricity is more active in dry conditions. With these materials, some take on a positive (+) charge and same have a negative (−) electrical charge, thus causing them to attract or cling. Clothing with similar charges repel each other, but that is not noticeable as is the clinging effect. Some clothes made of these materials will also start to cling to your legs as you walk, especially on days were the humidity is low or the air is dry. The skin becomes positive (+) in charge and the polyester clothes gain a negative (−) charge, thus causing them to attract.
Stopping static cling when drying clothesOne common method to reduce or eliminate static cling on clothes is to use fabric softener in the washer, use dryer sheets in the clothes dryer or to use an anti-static spray on the clothes. Unfortunately, these are chemical solutions that may harm the environment and cause allergic reaction in some people. Methods to reduce potential static cling include:

Hanger can reduce static cling SummaryStatic cling is an annoying effect from static electricity. Static cling is when clothes cling together after being removed from the dryer. It is caused by rubbing the various materials together when they are very dry. This problems can be reduced by treating the materials or eliminating the static electricity that causes them.

Do you ever pull your clothes out of the dryer and find that they are stuck together? What is this phenomenon? Why does it happen? Read more and learn about STATIC CLING! Behold: a dryer. (http://andreadekker.com/wp-content/uploads/2011/02/Washing-Machine.jpg) In AP Physics, we have been studying static electricity and in doing so we have seen how it relates to our lives! This was a great opportunity to understand why clothes tend to stick together after being in the dryer. The answer: static electricity! How exactly does static electricity make clothes stick? Static cling. When clothes move around in the dryer, they rub together and against the metal inside of the dryer. When this happens, electrons move from one object to the other, and some of the clothing becomes negatively charged and other pieces are positively charged. Because the charges are opposite, the charged pieces of clothing stick together! Is it possible to stop static cling? Yes (but then you won’t observe this wonderfully amazing physics concept 😦 )! There are many products that claim that they can absorb the electrons and take away the static charges. However, you can also avoid static cling by washing you clothing with fabric softener, which will reduce the amount of charge exchanged between the clothes and thus reduce the amount of static cling. Ah, physics! A wonderful part of our daily lives! Hope you learned something new…
