Article of apparel including fabric having interconnected cell structure

Abstract

An article of apparel includes at least one fabric panel including a first yarn having a first denier and a second yarn having a second denier. The first yarn forms an auxetic structure on the fabric panel comprising a pattern of interconnected segments defining cells, each cell having an interior area. The second yarn forms a fill portion extending between the interconnected segments of the auxetic structure and substantially fills the interior area of each cell.

         10 . The knit textile of  claim 9  wherein the first yarn type has a denier of about 100 and the third yarn type has a denier of about 33. 
     
     
         11 . The knit textile of  claim 7  wherein a denier ratio of the first yarn type to the third yarn type is about 3:1. 
     
     
         12 . The knit textile of  claim 2 , wherein a shape of each of the plurality of cells is a hexagon. 
     
     
         13 . The knit textile of  claim 12  wherein the hexagon is an auxetic hexagon. 
     
     
         14 . The knit textile of  claim 2 , wherein the perimeter has a higher stitch density than the central region. 
     
     
         15 . A textile having a knit construction and a first surface and a second surface opposite the first surface, the textile comprising:
 a first portion defining a perimeter comprising a first percentage by weight of a first yarn type, wherein the first yarn type is a polymer comprising at least one of polyester, nylon, thermoplastic polyurethane (TPU) and spandex fibers, and the perimeter of the first portion further comprising a second yarn type wherein the second yarn type is a polymer comprising at least one of polyester, nylon, thermoplastic polyurethane (TPU) and spandex fibers wherein the first yarn type and the second yarn type form at least a portion of the first surface and the second surface of the perimeter of the first portion of the textile; and   a second portion enclosed within the perimeter and comprising the second yarn type, wherein the second yarn type forms at least a portion of the first surface and the second surface of the second central portion of the textile, and wherein the first portion and the second portion integrally extend from one another.   
     
     
         16 . The textile of  claim 15 , wherein the textile further comprises a plurality of first portions and a plurality of second portions, wherein each portion of the plurality of second portions is isolated from each other throughout the textile and spaced apart from an adjacent second portion by at least one first portion, and wherein the plurality of first portions are interconnected throughout the textile. 
     
     
         17 . The textile of  claim 15 , wherein the textile is an air permeable textile defining a surface area wherein less than 25% of the surface area exposes direct openings through the fabric. 
     
     
         18 . An apparel item comprising:
