STRETCH WOVEN PALTEX’s collection of stretch woven fashion fabrics that contain lycra (spandex). The elasticity of stretch woven fabrics is achieved by weaving complex elastic yarns into the fabrics, which provide the added benefit of a little give and stretch making the fabric flow and relax while moving and sitting. These elastic yarns can be woven in the straight grain (called a warp stretch fabric), more commonly in the cross-grain (weft stretch fabric), or in both warp and weft.
