Even though ironing is boring, it is useful and necessary!
Ironing is indeed a tedious activity — one of the house chores that we want to avoid. But, did you know that ironing clothes might prevent several infectious diseases such as typhus and HIV? So, whenever you start ironing your clothes, think about this!
How Do Irons Work?
The electric clothes iron is an appliance that was revolutionary when it appeared on the market. It is an electrical appliance for the home, although also used for industries and commerce such as cleaners and clothing 
factories. The plates smooth out the clothes taking out wrinkles and marks. It works by smoothing the links between the long chains of polymer molecules that exist in the fibers of the material. The fibers stretch and maintain their new shape when cooled. It is a result of the weight of the generated heat. Some materials, such as cotton, need water or steam to loosen intermolecular bonds.
Modern irons have several innovative features
1) Generate steam; for this, you have a water tank.
2) Thermostat to keep the temperature constant.
3) Anti-burn control, if the iron is left a long time on the garment, it turns off automatically.
4) Water indicator that indicates how much water is in the container.
5) Side platform that prevents the iron from being in contact with the garments, and keeps it upright.
6) Dial with temperature control that shows the ideal temperature for different clothes.
7) Steam-device, which sends steady steam to the garments.
8) Energy-saving control, if the iron is left on and not used, after 10 minutes, it automatically turns off.
9) Control of the amount of steam to be emitted cost-effectively.
