We know that the commonly used fabrics for backpacking are roughly divided into cotton, polyester, nylon and other materials, and the webbing used for backpack is basically made of these three materials. In fact, fabric and webbing are all spun with the same yarn. Cotton webbing is matte and looks like canvas, which is a natural and environmental protection product. The nylon webbing surface is bright, the yarn is very tight, and the toughness is very strong. The automobile safety belt is made of nylon webbing. Polyester webbing has high plasticity, and its surface can be made like nylon webbing or cotton webbing, which is also cheap, so polyester webbing is often used as their substitute.
