If someone was concerned about it, it's not difficult to place the string just inside your body for a short while, the visit the restroom and remove the string. I've done that when wearing a swimsuit and was concerned about the string poking out of the suit.
My understanding is they can't see inside the body, so if the string is entirely inside your body, you theoretically would be fine. However it is a small string. How does the scanner tell the cotton string from the cotton fabric of your underwear?
