This invention describes a specialized fabric component for items like shoes or clothing. It's made from two distinct layers, both created by braiding yarns together. The first layer is a tube-like braid, and the second layer is also braided, but uses a stiffer type of yarn than the first layer.
Why it matters: Since 2022, improvements in automated braiding machinery and the availability of diverse performance yarns have likely made it more practical to precisely manufacture these multi-layered components with specific elastic properties.
