Most heated clothing is designed for cold-weather sports and activities, such as motorcycle riding, downhill skiing, diving, winter biking, and snowmobiling, trekking and for outdoor workers such as construction workers and carpenters. Since the London Olympics, heated clothing has also been used by athletes to keep their muscles warm between ...
A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating .
A clothes iron (also flatiron, smoothing iron, dry iron, steam iron or simply iron) is a small appliance that, when heated, is used to press clothes to remove wrinkles and unwanted creases. Domestic irons generally range in operating temperature from between 121 °C (250 °F) to 182 °C (360 °F).
The heating is commonly done to a temperature of 180–220 °C (360–430 °F), depending on the fabric. [2] Ironing works by loosening the bonds between the long-chain polymer molecules in the fibres of the material. While the molecules are hot, the fibres are straightened by the weight of the iron, and they hold their new shape as they cool.
Electric heating devices can be built in any required size and can be located anywhere within a plant. Electric heating processes are generally clean, quiet, and do not emit much byproduct heat to the surroundings. Electrical heating equipment has a high speed of response, lending it to rapid-cycling mass-production equipment.
Much like heating pads, electric blankets use an insulated wire or heating element inserted into a fabric that heats when it is plugged in. The temperature control unit, located between the blanket and the electrical outlet, manages the amount of current entering into the heat elements in the blanket.
The heating coil is the actual resistance which is where the electrical load occurs. The most common type of metal alloy used for this purpose is a nickel-chromium mixture, also known as nichrome. [6] The nichrome wire is wound around a ceramic core, and the number of spirals per inch vary according to the requested watt density.
The heating element in most dryers is a bare, coiled nichrome wire that is wrapped around mica insulators. Nichrome is used due to its high resistivity, and low tendency to corrode when heated. [11] A survey of stores in 2007 showed that most hair dryers had ceramic heating elements (like ceramic heaters) because of their "instant heat ...
