This is new information to me!

Tread lines are created using a specific weaving technique known as ‘tread weaving.’ This technique involves alternating the tension of the warp and weft threads to create raised lines on the fabric’s surface. The process requires precision and skill, as the lines must be evenly spaced and consistent in depth to ensure the towel’s functionality.

The tread weaving technique is often used in combination with other weaving methods, such as the dobby weave, to create towels with complex patterns and enhanced absorbency. The resulting fabric is not only functional but also visually appealing, making it a popular choice for high-quality bath towels.
