According to Upworthy, these lines also help towels wick moisture more effectively—a subtle yet essential feature for everyday use. One key role of these ridges is enhancing absorbency. By increasing the towel’s surface area, they allow it to soak up water more efficiently. They also promote airflow across the fabric, which helps the towel dry faster and prevents mildew from forming.
Lines serve a practical purpose beyond performance as well. They often act as visual guides for folding or hanging towels neatly. This thoughtful design detail helps the towel maintain its shape and appearance over time, ensuring it remains both functional and attractive in your bathroom.
