This is new information to me!

The lines on bath towels are primarily designed to improve their functionality. These lines, often referred to as ‘tread lines,’ are created through specific weaving techniques that enhance the towel’s ability to absorb water. Typically, these lines are spaced evenly across the towel, with each line measuring about 1 to 2 centimeters in width. The spacing and depth of these lines are crucial as they increase the surface area of the towel, allowing it to soak up more moisture efficiently.

In addition to absorbency, the lines also play a role in the towel’s structural integrity. By creating a pattern of raised and lowered sections, the lines help distribute stress across the fabric. This distribution reduces wear and tear, prolonging the life of the towel. The strategic placement of these lines ensures that the towel remains soft and pliable, even after multiple washes.

The absorbency of a towel is one of its most critical features, and the lines on a towel significantly contribute to this property. The lines create channels that guide water into the deeper layers of the towel, allowing it to hold more moisture. This is particularly important for towels made from materials like cotton, which have natural absorbent properties. The lines enhance these properties by increasing the towel’s surface area, which can be as much as 20% more than a flat towel.

Moreover, the lines help the towel dry faster after use. By creating ridges and valleys, the lines allow air to circulate more freely around the towel, speeding up the evaporation process. This not only makes the towel more convenient to use but also helps prevent the growth of mold and bacteria, which thrive in damp environments.
