Title: BRAIDED DOUBLE LAYER TUBE FOR SINGLE LAYER FOOTWEAR UPPER
Abstract:
A method of manufacturing a braided footwear upper is provided. The method includes braiding a two-layer, single-tube structure with a first end that couples a first braided layer to a second braided layer, and second end that couples the first braided layer to the second braided layer of the tubular braided structure. The first end is proximate the second end. At least one yarn from the first end, and at least one yarn from the second end are braided with at least one draw yarn. The draw yarn is braided to be easily removable, such that the first end is selectively de-coupled from the second end. When the draw yarn is removed, the double-layer tubular braided structure is expandable to form a larger diameter tubular braided structure.
