Abstract
An article of apparel includes a base layer defined by a Poisson's ratio, and a polymer structure coupled to the base layer. The polymer structure is configured to lower the Poisson's ratio of the base layer. The polymer structure includes a plurality of interconnected members forming an array of cell units. The plurality of interconnected members form cell walls with interior recesses defined within the cell walls.
Claims20
An article of apparel comprising:
- a first layer;
- and
- a second layer coupled to the first layer, the second layer comprising a repeating pattern of shapes defined by interconnected perimeter walls and interior recesses, wherein the interconnected perimeter walls and interior recesses define at least one first region and at least one second region on the second layer, wherein each interior recess in the first region provides a void exposing the base layer, and wherein each interior recess in the second region is at least partially filled with a recess material that covers the first layer.
An article of apparel comprising:
- a stretch fabric defined by a Poisson's ratio;
- and
- a polymer structure coupled to the stretch fabric and configured to lower the Poisson's ratio of the stretch fabric, the polymer structure including a plurality of interconnected members forming an array of cell units.
A functional laminate for an article of apparel, the functional laminate comprising:
- a first layer possessing a first expansion pattern defined by a first Poisson's ratio;
- and
- a second layer connected to the first layer and possessing a second expansion pattern defined by a second Poisson's ratio that is less than the first Poisson's ratio;
- wherein the first layer and the second layer are configured such that,
- when a load is applied to the functional laminate, the second expansion pattern of the second layer dominates the first expansion pattern of the first layer to drive expansion of the functional laminate;
- and
- when the load is removed from the functional laminate, the first expansion pattern of the first layer dominates the second expansion pattern of the second layer to drive retraction of the functional laminate.
