Why Do Bath Towels Have That Weird Line?A simple question
recently went viral: What’s that odd raised line on bath
towels for? Social media lit up with wild guesses—from “a
face-to-butt divider” to “racing stripes for faster drying.”
But the real answer? It’s called a dobby border—and it’s all about function.
Textile experts explain that this woven strip reinforces the towel’s edges,
preventing fraying after repeated washes.
It also keeps towels from becoming bulky and helps them stay soft and lightweight.
Plus, it gives a neat folding guide and a polished
look on your rack or shelf.So next time you notice that mysterious line,
know it’s not just for style—it’s towel engineering at its finest.
