Everyone knows that steam helps a lot with ironing. But only a few know why and how. Read the below and get enlightened about this rather hot topic.
Reshaping fabric
What is ironing, anyway? It is the reshaping of textile fabric from wrinkled to smooth. Simple enough on the surface, quite interesting when you look closely: The heat of the iron loosens the connection between the molecule-chains in the fibres. The pressure of the soleplate then reshapes the fabric, and when it cools down, the connections between the molecule-chains rebuild. So what was a stubborn crease is now smooth and will stay that way (until it is worn and washed again…).
Steam speeds up heating up
Compared to „dry“ ironing, using steam speeds up the heating of the fabric considerably. The reason is that steam transports heat quicker than dry air, so the heat permeates the fabric a lot faster and deeper with steam. This is another way of saying that with steam, you iron faster.
Moisture needed
Steam is not only a highly efficient mode of transport of heat. Steam is water turned to gas and normally contains tiny water droplets - that is what you see when steam comes from your steam iron. So steam is also transporting moisture into the fabric, which is essential for natural materials like cotton.
Не всегда вода кипит при 100 °C
В школе нас учили, что при 100 °C вода закипает и превращается в пар. Так оно и есть, но это относится только к нормальному атмосферному давлению на уровне моря. Поэтому если вы не живете на горной вершине, то пар, выходящий из вашего утюга имеет температуру 100 °C. В утюге с парогенератором пар образуется под давлением в отдельном узле. И чем выше там давление, тем позже закипает вода, и тем горячее пар: пар, образующийся при давлении 5 ат, имеет температуру 150°C. Поэтому более высокое давление делает пар горячее и позволяет ему проникать сквозь ткань быстрее и глубже.
