Claims18
A circularly-woven tube for an article of footwear comprising:
- a plurality of warp yarns, having a first elastic modulus;
- a plurality of weft yarns, having a second elastic modulus;
- and
- wherein at least at least one of least one weft yarn or at least one warp yarn comprises elastane covered by PET;
- wherein the second elastic modulus is smaller than the first elastic modulus;
- and wherein a first type of warp yarns is arranged in a first area and a second type of warp yarns is arranged in a second area of the circularly-woven tube;
- wherein the first type of warp yarns has a first bending stiffness and the second type of warp yarns has a second bending stiffness, and the second bending stiffness is greater than the first bending stiffness;
- and
- wherein the second elastic modulus is less than 1 GPa.
