The real purpose of those mysterious lines
1. A Viral Question
A viral post asked about the raised line running across many bath towels,
joking it was a “face-to-butt separator” or a towel’s “racing stripe.”
The real answer is more practical.
2. What It Is
The line is called a dobby border.
While decorative, it has an important function:
helping towels hold their shape and last longer, even after many washes.
3. Benefits of the Dobby Border
Textile experts say it reinforces edges to prevent fraying,
keeps towel ends from getting bulky, and helps towels fold neatly while staying soft and absorbent.
4. Added Design
Manufacturers can also use the dobby border for subtle patterns, textures, or logos without affecting comfort.
That small line is a thoughtful feature that makes towels more durable, functional, and attractive.
