A seemingly simple question about the raised line on bath towels
recently sparked a viral debate on social media. People shared humorous
theories, with suggestions ranging from “face-to-butt separation line” to
“racing stripes” for faster drying. However, the real answer is much more practical.
That line is called the dobby border, and it serves several functional purposes.
It reinforces the towel’s edges, preventing fraying and wear over time. It also helps
maintain the towel’s shape, ensuring it stays lightweight and absorbent. The dobby
border allows for aesthetic designs and branding but is primarily there to improve the towel’s performance and durability.
In addition to its functional benefits, it gives towels a cleaner, more symmetrical look
when folded or hung. So next time you grab your towel, appreciate the dobby
border—it’s working to keep your towel strong, soft, and stylish.
