Abstract: A system for manufacturing a scrim material reinforced by a plurality of yarns includes a yarn dispenser to support and space the plurality of yarns in a yarn pattern, a nipping roll including the scrim material for mating to the yarn pattern, forming the scrim, a guide coupled to the yarn dispenser and positioned within the yarn pattern, the guide providing a first retainer for maintaining the yarn pattern, and a selvage thread assembly extending from the guide and coupling the guide to the nipping roll. The selvage thread assembly includes a spindle and a selvage thread having a first end coupled to the spindle and a second end coupled to the nipping roll, the selvage thread positioned within the yarn pattern, providing a second retainer for maintaining the yarn pattern until the yarn pattern is mated to the scrim material.

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).

Abstract: A warp oriented woven sailcloth is provided in warp yarns are relatively uncrimped relative to the fill yarns. The yarn weight ratios (fill vs. warp) are 1.0 to 1 and 0.22 to 1.
