Abstract

First warp yarns and second warp yarns are each interwoven with weft yarns to produce a one-layer, lightweight, stretchable fabric. The first warp yarns include stretchable yarns that are activatable to achieve a contracted state, and the second warp yarns include non-stretchable yarns. The first warp yarns may include a stretchable core yarn with non-stretchable wrap yarn wrapped around the stretchable core yarn. The first warp yarns may be in an alternating arrangement with the second warp yarns. When the yarns are woven together, the first warp yarns are in an extended state and the second warp yarns are in an unbunched state. The fabric then undergoes a finishing procedure during which the first warp yarns are activated to achieve a contracted state. The second warp yarns thus achieve a bunched state, and the resulting fabric is stretchable in the warp direction.
