Lines on Bath Towels: 7 Surprising Facts Explained

Have you ever looked at the woven strips near the ends of your towels and wondered why they are there? The lines on bath towels are so common that most people barely notice them—until the borders shrink, become wavy, or make the towel difficult to fold.

These lines are generally known as dobby borders. They are flat woven sections positioned close to one or both ends of a terry towel. Depending on the design, a towel may have one wide border, several narrow lines, or a decorative pattern woven into the border.

The dobby border contributes to the towel’s appearance and may provide additional structure near its ends. It can help the fabric retain its shape and resist fraying, but it is not the primary part responsible for drying your skin. Most absorbency comes from the raised cotton loops that cover the main body of the towel.

The red markers in the supplied image highlight the area where these woven borders appear on folded towels. They are not random decorations, instructions for folding, or marks dividing the towel into clean and dirty sections.

Here is what the lines actually do, why they sometimes shrink, and how you can keep your towels soft, absorbent, and neatly shaped.

What Are the Lines on Bath Towels Called?

Understanding the lines on bath towels begins with recognizing the difference between the flat dobby border and the raised terry loops.

The lines on bath towels are commonly called dobby borders, dobby bands, or decorative woven borders.

A dobby border is produced using a controlled weaving method that creates small geometric patterns, textured stripes, or flat bands. Unlike the fluffy terry area, it normally has fewer or no raised loops.

The main body of a bath towel is generally made from terry cloth. Terry fabric contains loops that increase its surface area and allow it to collect moisture from the skin.

The border is more tightly woven and structurally different. This explains why it feels flatter and less absorbent than the rest of the towel.

Dobby borders can be found on:

• Bath towels
• Hand towels
• Washcloths
• Bath sheets
• Hotel towels
• Kitchen towels
• Decorative guest towels
• Spa towels

They appear on both affordable and luxury towel collections. For example, textile manufacturer Standard Textile describes its Classic Dobby towels as ring-spun cotton towels accented with dobby borders.

Seven Facts About the Lines on Bath Towels

1. They Are Woven Into the Towel

The border is normally part of the towel’s construction rather than a separate ribbon sewn onto the surface.

During manufacturing, the loom changes the weave structure to create the flat line or decorative pattern. When the dobby section ends, the machine returns to forming the looped terry fabric.

Because the border is woven into the towel, it generally remains attached through repeated washing. However, the difference between the tight border and loose terry loops may create uneven shrinkage over time.
