Ironing facts for kids
Ironing is the use of a heated tool (an iron) to remove wrinkles from fabric. The heating is commonly done to a temperature of 180–220 °Celsius, depending on the fabric. Ironing works by loosening the bonds between the long-chain polymer molecules in the fibers of the material. While the molecules are hot, the fibers are straightened by the weight of the iron, and they hold their new shape as they cool. Some fabrics, such as cotton, require the addition of water to loosen the intermolecular bonds. Many modern fabrics (developed in or after the mid-twentieth century) are advertised as needing little or no ironing. Permanent press clothing was developed to reduce the ironing necessary by combining wrinkle-resistant polyester with cotton.
The first known use of heated metal to "iron" clothes is known to have occurred in China. The electric iron was invented in 1882, by Henry W. Seeley. Seeley patented his "electric flatiron" on June 6, 1882 (U.S. Patent no. 259,054).
The iron is the small appliance used to remove wrinkles from fabric. It is also known as a clothes iron, flat iron, or smoothing iron. The piece at the bottom is called a sole plate. Ironing uses heat energy, chemical energy, electrical energy, and mechanical energy.
Most ironing is done on an ironing board, a small, portable, foldable table with a heat-resistant surface. Some commercial-grade ironing boards incorporate a heating element and a pedal-operated vacuum to pull air through the board and dry the garment.
On 15 February 1858 W. Vandenburg and J. Harvey patented an ironing table that facilitated pressing sleeves and pant legs. A truly portable folding ironing board was first patented in Canada in 1875 by John B. Porter. The invention also included a removable press board used for sleeves. In 1892 Sarah Boone obtained a patent in the United States for improvements to the ironing board, allowing for better quality ironing for shirt sleeves.
