Abstract

The present disclosure describes a hydroentangled woven fabric. The hydroentangled woven fabric includes a plurality of warp yarns and a plurality of weft yarns interwoven with the plurality of warp yarns to define the hydroentangled woven fabric. The hydroentangled woven fabric has a first side and a second side opposite the first side. The hydroentangled fabric has a plurality of compact interstitial spaces between the plurality of warp yarns and the plurality of weft yarns. The plurality of warp yarns and the plurality of weft yarns are bulky around the compact interstitial spaces. The hydroentangled fabric has a compact thickness that extends in a direction from the first side of the hydroentangled woven fabric to the second side of the hydroentangled woven fabric. The compact thickness and bulky warp and weft yarns give rise to a compact and moisture wicking hydroentangled woven fabric.
