Iron

Well, one may think irons are not needed in 3D, however, it is not like this. 3D irons, being small appliances, play a very important role in 3D people live since there is no other way to remove 3D wrinkles from 3D fabric. 3D irons easily loosen the ties between the long chains of molecules that exist in 3D polymer fiber materials. With the heat and the weight of the 3D ironing plate, the 3D fibers are stretched and the 3D fabric maintains its new shape when cool. Some materials such as 3D cotton require the use of 3D water to loosen the 3D intermolecular bonds. So, modern 3D irons contain 3D water.
