Why do clothes wrinkle?
Show answer & explanation
Answer: Fabric fibers bend and set
Fabric fibers bend and set ✓ — Correct! Fabric is made of long molecular chains. When compressed or twisted, these chains form new bonds in the bent position. Heat and moisture break these bonds—that's why ironing and steaming remove wrinkles!
Clothes shrink unevenly — Wrong. Wrinkling isn't about size changes. It's about fiber molecules bonding in bent positions.
Air pressure flattens them — Wrong. Air pressure doesn't cause wrinkles. They form from fabric being compressed, folded, or twisted.
