Abstract
In a woven fabric all warp and weft yarns are elastic, all weft and warp yarns have a stretchable core comprising a first elastic fiber and a second fiber that is less elastic than said first fiber, and the elasticity of the fabric in warp direction is at least 25% and elasticity of the fabric in weft direction (Eweft) is at least 30%, preferably at least 40%.
Claims9
A woven fabric comprising elastic warp yarns and elastic weft yarns,
- said elastic warp yarns and elastic weft yarns each having a stretchable core and an inelastic fibers sheath covering said core, said stretchable core including a first elastic fiber and a second fiber that is less elastic than said first elastic fiber,
- said woven fabric having an elasticity in warp direction of at least 25% (measured according to ASTM D3107-Stretch) and elasticity in weft direction of at least 40% (measured according to ASTM D3107-Stretch), and
- said elastic warp yarns having a twist level with a twist multiplier in the range of 2.5 to 6,
- wherein elasticity of the fabric in weft direction (Eweft) is higher than the elasticity in warp direction (Ewarp) or wherein elasticity of the fabric in warp direction (Ewarp) is higher than elasticity in the weft direction (Eweft).
