To remove wrinkles from nylon fabric, such as a nylon flag, requires using a low heat setting to avoid damaging the material. A sturdy material, nylon has a dirt- and chemical-resistant construction, allowing it to retain its quality when used as a flag outdoors. Nylon flags become wrinkled from wet, cold or hot conditions and need to be ironed occasionally to allow the fabric to flow freely in the wind.

Iron a nylon flag on the lowest warm setting.

Step 1

Remove any pole attached to the nylon flag if possible for easier ironing.

Step 2

Set the iron to the lowest heat or gentle setting.

Step 3

Stretch one end of the nylon flag over the ironing board, allowing the remainder of the flag to hang down the back of the board.

Step 4

Smooth the flag with your hand to remove any wrinkles before applying the iron.

Step 5

Iron the flag using back-and-forth movements and medium pressure. After ironing the section, pick the flag up at the back of the board and bring it forward. Position the next un-ironed section onto the ironing board and smooth it out. Iron the flag in the same manner. Continue the procedure, ironing the entire flag.
