Abstract

A terry article includes a ground component including a plurality of ground warp yarns and a plurality of weft yarns, and a pile component disposed on at least one of a lower side and an upper side of the ground component. The pile component includes a first plurality of piles that extend away from the ground component along a vertical direction. The first plurality of piles are formed from a first set of pile yarns comprised of natural fibers and further define a first pile height. The pile component also includes a second plurality of piles that extend away from the ground component in the vertical direction. The second plurality of piles are formed from a blend of cotton yarns and thermoplastic staple fibers and define a second pile height that is less than the first pile height.
