A clothes iron is a small appliance that, when heated, is used to press clothes to remove creases and help prevent the spread of infectious diseases. Domestic irons generally range in operating temperature from between to. It is named for the metal of which the device was historically made, and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate, the fibers are stretched and the fabric maintains its new shape when cool. Some materials, such as cotton, require the use of water to loosen the intermolecular bonds. Before the introduction of electricity, irons were heated by combustion, either in a fire or with some internal arrangement. An "electric flatiron" was invented by American Henry W. Seeley and patented on June 6, 1882. It weighed almost 15 pounds and took a long time to heat. The UKElectricity Association is reported to have said that an electric iron with a carbon arc appeared in France in 1880, but this is considered doubtful.
History and development
Metal pans filled with hot coals were used for smoothing fabrics in China in the 1st century BC. From the 17th century, sadirons or sad irons began to be used. They were thick slabs of cast iron, triangular and with a handle, heated in a fire or on a stove. These were also called flat irons. A later design consisted of an iron box which could be filled with hot coals, which had to be periodically aerated by attaching a bellows. In Kerala in India, burning coconut shells were used instead of charcoal, as they have a similar heating capacity. This method is still in use as a backup device, since power outages are frequent. Other box irons had heated metal inserts instead of hot coals. Another solution was to employ a cluster of solid irons that were heated from a single source: As the iron currently in use cooled down, it could be quickly replaced by a hot one. In the late nineteenth and early twentieth centuries, there were many irons in use that were heated by fuels such as kerosene, ethanol, whale oil, natural gas, carbide gas, or even gasoline. Some houses were equipped with a system of pipes for distributing natural gas or carbide gas to different rooms in order to operate appliances such as irons, in addition to lights. Despite the risk of fire, liquid-fuel irons were sold in U.S. rural areas up through World War II. In the industrialized world, these designs have been superseded by the electric iron, which uses resistive heating from an electric current. The hot plate, called the sole plate, is made of aluminium or stainless steel polished to be as smooth as possible; it is sometimes coated with a low-friction heat-resistant plastic to reduce friction below that of the metal plate. The heating element is controlled by a thermostat that switches the current on and off to maintain the selected temperature. The invention of the resistively heated electric iron is credited to Henry W. Seeley of New York City in 1882. In the same year an iron heated by a carbon arc was introduced in France, but was too dangerous to be successful. The early electric irons had no easy way to control their temperature, and the first thermostatically controlled electric iron appeared in the 1920s. Later, steam was used to iron clothing. Credit for the invention of the steam iron goes to Thomas Sears. The first commercially available electric steam iron was introduced in 1926 by a New York drying and cleaning company, Eldec, but was not a commercial success. The patent for an electric steam iron and dampener was issued to Max Skolnik of Chicago in 1934. In 1938, Skolnik granted the Steam-O-Matic Corporation of New York the exclusive right to manufacture steam-electric irons. This was the first steam iron to achieve any degree of popularity, and led the way to more widespread use of the electric steam iron during the 1940s and 1950s.
Types and names
Historically, irons have had several variations and have thus been called by many names:
Flatiron, flat iron or smoothing iron
Sad iron or sadiron
Box iron, ironing box, charcoal iron, ox-tongue iron or slug iron
Goose, tailor's goose or, in Scottish, gusing iron
Goffering iron
Hygiene
Proper ironing of clothes has proven to be an effective method to avoid infections like those caused by lice
Features
Modern irons for home use can have the following features:
A design that allows the iron to be set down, usually standing on its end, without the hot soleplate touching anything that could be damaged;
A thermostat ensuring maintenance of a constant temperature;
A temperature control dial allowing the user to select the operating temperatures ;
An electrical cord with heat-resistant silicone rubber insulation;
Injection of steam through the fabric during the ironing process;
* A water reservoir inside the iron used for steam generation;
* An indicator showing the amount of water left in the reservoir,
* Constant steam: constantly sends steam through the hot part of the iron into the clothes;
* Steam burst: sends a burst of steam through the clothes when the user presses a button;
* Dial controlling the amount of steam to emit as a constant stream;
* Anti-drip system;
Cord control: the point at which the cord attaches to the iron has a spring to hold the cord out of the way while ironing and likewise when setting down the iron ;
A retractable cord for easy storage;
non-stick coating along the sole plate to help the iron glide across the fabric
Anti-burn control: if the iron is left flat for too long, the iron shuts off to prevent scorching and fires;
Energy saving control: if the iron is left undisturbed for several minutes, the iron shuts off.
Cordless irons: the iron is placed on a stand for a short period to warm up, using thermal mass to stay hot for a short period. These are useful for light loads only. Battery power is not viable for irons as they require more power than practical batteries can provide.
3-way automatic shut-off
self-cleaning
Anti scale to help to remove lime scale buildup of using hard water for long time.
vertical steam to help to remove creases and wrinkles by holding an iron vertically and steaming material close to it.
Collections
One of the world's larger collection of irons, comprising 1300 historical examples of irons from Germany and the rest of the world, is housed in Gochsheim Castle, near Karlsruhe, Germany. Many ethnographical museums around the world have collections of irons. In Ukraine, for example, about 150 irons are the part of the exhibition of the Radomysl Castle in Ukraine.
Ironing center
An ironing center or steam ironing station is a device consisting of a clothes iron and a separate steam-generating tank. By having a separate tank, the ironing unit can generate more steam than a conventional iron, making steam ironing faster. Such ironing facilities take longer to warm up than conventional irons, and cost more.
