Static cling is the tendency for light objects to stick (cling) to other objects owing to static electricity. It is common in clothing, but occurs with other items, such as the tendency of dust to be attracted to, and stick to, plastic items.
In clothing, static cling occurs from static electricity. An electrostatic charge builds up on clothes due to the triboelectric effect when pieces of fabric rub against each other, as happens particularly in a clothes dryer. The separate positive and negatively charged surfaces attract each other. It is especially noticeable when humidity is low, allowing static electricity to build up. Certain substances can reduce static cling and are often included in fabric softener and dryer sheets. Antistatic agents, which make the surfaces slightly conductive, can be used on fabrics.
Dust accumulation caused by static cling is a significant issue for computers and other electronic devices with heat generating components that need to be cooled by airflow. Dust is carried into the computer by the airflow created by case- and component fans. The accumulated dust covers metal surfaces and clogs the empty space between the fins of heatsinks, diminishing the dissipation of heat and interrupting the outward flow of warm air. Especially for critical components such as microprocessors and memory banks, this raises the risk of them overheating which can ultimately damage or destroy them. To compensate, automatically controlled fans will raise their speed, generating more noise and shortening their lifespan. An additional risk is the (small) electrical conductivity of dust which, given enough accumulation of dust, can cause critical damage to the device's internal components. Dust accumulation grows exponentially, since the accumulated dust creates new static surfaces and physical blockades for new dust to cling to.
Advertisers in urban areas, eager to use guerilla marketing techniques, have turned to static cling as a distribution medium. In an advertising campaign for Microsoft's MSN 8 Internet service, on October 24, 2002, hundreds of decals of the MSN butterfly logo were affixed to surfaces in New York City and the New York Times reported that it was static cling that held them there.

The triboelectric effect describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material. It is ubiquitous, and occurs with differing amounts of charge transfer (tribocharge) for all solid materials. There is evidence that tribocharging can occur between combinations of solids, liquids and gases, for instance liquid flowing in a solid tube or an aircraft flying through air.
Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor.
A clothes dryer is a powered household appliance that is used to remove moisture from a load of clothing, bedding and other textiles, usually after they are washed in the washing machine.
Microfibre is synthetic fibre finer than one denier or decitex/thread, having a diameter of less than ten micrometers.
Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as central processing units (CPUs), chipsets, graphics cards, hard disk drives, and solid state drives.
A clothes line, also spelled clothesline, also known as a washing line, is a device for hanging clothes on for the purpose of drying or airing out the articles. It is made of any type of rope, cord, or twine that has been stretched between two points, outdoors or indoors, above ground level. Clothing that has recently been washed is hung over the line to dry, held in place using clothes pegs or clothespins. Washing lines are attached either from a post or a wall, and are frequently located in back gardens, or on balconies. Longer washing lines often have props holding up the mid-section so the weight of the clothing does not pull the clothesline down to the ground.
A hair dryer, hairdryer, hairdrier, or blow dryer is an electromechanical device that blows ambient or hot air over damp hair to speed the evaporation of water to dry the hair. Blow dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand. These bonds are powerful but are temporary and extremely vulnerable to humidity. They disappear with a single washing of the hair.
A fabric softener or fabric conditioner is a conditioner applied to laundry after it has been washed in a washing machine. A similar, more dilute preparation meant to be applied to dry fabric is known as a wrinkle releaser.
An electrostatic precipitator (ESP) is a filterless device that removes fine particles, such as dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air purifiers, which use disposable filters to remove dust.
All electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. There are several techniques for cooling including various styles of heat sinks, thermoelectric coolers, forced air systems and fans, heat pipes, and others. In cases of extreme low environmental temperatures, it may actually be necessary to heat the electronic components to achieve satisfactory operation.
Polar fleece is a soft fabric made from polyester that is napped and insulating.
Static wicks, also called static dischargers or static discharge wicks, are devices used to remove static electricity from aircraft in flight. They take the form of small sticks pointing backwards from the wings, and are fitted on almost all civilian aircraft.
A combo washer dryer is a combination in a single cabinet of a washing machine and a clothes dryer. It should not be confused with a "stackable" combination of a separate washing machine and a separate clothes dryer.
An antistatic device is any device that reduces, dampens, or otherwise inhibits electrostatic discharge, or ESD, which is the buildup or discharge of static electricity. ESD can damage electrical components such as computer hard drives, and even ignite flammable liquids and gases.
An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD).
A dryer ball is a spherical laundry device for tumbling clothes dryers used as an alternative to fabric softener, reducing static electricity or softening clothing, or to accelerate the drying process.
Lint is the common name for visible accumulations of textile fibers, hair and other materials, usually found on and around clothing. Certain materials used in the manufacture of clothing, such as cotton, linen, and wool, contain numerous, very short fibers bundled together. During the course of normal wear, these fibers may either detach or be jostled out of the weave of which they are part. This is the reason why heavily used articles such as shirts and towels become thin over time and why such particles accumulate in the lint screen of a clothes dryer.
Fabric treatments are processes that make fabric softer, or water resistant, or enhance dye penetration after they are woven. Fabric treatments get applied when the textile itself cannot add other properties. Treatments include, scrim, foam lamination, fabric protector or stain repellent, anti microbial and flame retardant.
