According to Upworthy, these lines also enhance moisture-wicking. By increasing surface area and airflow within the fabric, towels are able to pull water away from your skin more effectively and release it faster as they dry.

How Towel Lines Improve Absorbency and Drying
One of the main benefits of these lines is improved absorbency. The raised or tightly woven areas increase the towel’s surface area, allowing it to soak up more moisture with less effort.
At the same time, the lines create small channels that allow air to circulate through the fabric. This helps towels dry faster between uses—an important factor in preventing musty odors and mildew. Faster drying also reduces stress on the fibers, helping towels last longer.
As an added bonus, the lines often act as visual guides, making towels easier to fold neatly or hang evenly.
