Why does pressing clothes with hot iron works while using cold iron doesn’t ?

In: Chemistry

The hot iron also uses water to create steam. The steam “softens” the fabric, the hot iron presses it flat and dries any moisture left by the steam.

Techically, a cold iron would also work, it would just take longer. Get the wrinkly spot wet, set cold iron on to keep it flat, the wait for it to dry.
