Abstract
As an example of a specific fabric, the fabric would comprise 52 yarns per inch of 350 denier polyester in the warp and 132 yarns per inch of 150 denier in the fill. Using the above density calculation, this would result in a cloth having a warp density of 973 and a fill density of 1617. When viewed at high magnification, the warp yarns (41) are relatively uncrimped as compared to the textured fill yarns (43), as illustrated by the scanning electron microscope photo shown in FIG. 5 and the densities are sufficient to provide a fabric having good stretch resistance along the bias and the warp (see e.g., FIGS. 1 and 2).
