Abstract
A garment includes at least one garment panel made of a fabric including a first yarn having a first denier and a second yarn having a second denier, the first denier being greater than the second denier. The first yarn forms an auxetic structure comprising a pattern of interconnected segments on the garment panel. The second yarn forms a fill portion extending between the interconnected segments of the auxetic structure.
Claims19
A garment comprising:
- at least one garment panel comprising a fabric including a first yarn having a first denier, a second yarn having a second denier, and a third yarn comprised of elastane fibers and having a third denier, the first denier greater than the second denier, the first yarn and the third yarn forming an auxetic structure comprising a pattern of interconnected segments defining cells, each cell having an interior area, wherein both the first yarn and the third yarn form each of the interconnected segments, the second yarn and the third yarn forming a fill portion extending between the interconnected segments of the auxetic structure in the interior area of each cell, wherein the second yarn and the third yarn are stitched together such that at least 75% of the interior area of each cell is covered by the second yarn or third yarn and less than 25% of the interior area exposes direct openings through the fabric.
A garment comprising:
- at least one panel comprising a first material having a first modulus of elasticity and a second material having a second modulus of elasticity, the first modulus of elasticity greater than the second modulus of elasticity;
- an auxetic structure provided by the first material on the panel, the auxetic structure comprising a pattern of reentrant shapes;
- and
- a fill portion provided by the second material on the panel, the fill portion formed by a plurality of stitches positioned inside of each reentrant shape of the auxetic structure;
- wherein the fill portion is a base layer of the at least one panel and the auxetic structure is an auxetic layer positioned on the base layer;
- and
- wherein the base layer and the auxetic layer are provided as a warp-knit fabric, the auxetic layer exposed a first side of the fabric but not exposed on a second side of the fabric.

A garment comprising:
- a torso panel comprised of a fabric including an auxetic structure and a fill portion, the auxetic structure including a plurality of interconnected segments defining a repeating pattern of reentrant shapes, each of the reentrant shapes including parallel end segments defining a bar direction, the fill portion formed by a plurality of stitches positioned inside of each reentrant shape of the auxetic structure, wherein the bar direction is arranged in a latitudinal direction on the torso panel;
- and
- a limb panel connected to the torso panel, the limb panel comprised of the fabric including the auxetic structure, the bar direction of the auxetic structure arranged in a longitudinal direction on the limb panel;
- the fabric including a first yarn having a first denier, a second yarn having a second denier less than the first denier, and a third yarn comprised of elastane fibers, the parallel end segments of the auxetic structure comprised of the first yarn and the third yarn, and the fill portion comprised of the second yarn and the third yarn.
