Abstract: There is provided herein a woven sailcloth having a weight of at least about 6 and comprising warp yarns and fill yarns and having a 1% warp of at least about 80 and/or a warp efficiency of at least about 13, wherein the fill yarns are pre-crimped, and wherein the warp yarns and the fill yarns are weaved in a plain weave in which the ratio of fill yarn count to warp yarn count is about 1.1:1 to about 1.8:1 and the ratio of warp yarn density to fill yarn density is about 1.2:1 to about 1.9:1. There is also provided herein sails made from the sailcloth and a method for making the sail.

Abstract: A method of reducing crimp in woven sailcloth comprising applying heat to warp yarn or fill yarn prior to the yarns being woven into fabric and a method of making a sail comprising assembling panels of sailcloth comprising warp yarns and fill yarns, wherein at least one panel of sailcloth is prepared by applying heat to the warp yarn or the fill yarn prior to the yarns being weaved into fabric.
Abstract: A woven sailcloth comprising warp yarns and fill yarns and having one or more of (i) a 1% warp of at least about 125 and/or a warp efficiency of at least about 17, (ii) a plain weave in which the ratio of fill yarn count to warp yarn count is about 1.1:1 to about 1.8:1 and the ratio of warp yarn density to fill yarn density is about 1.2:1 to about 1.9:1, and (iii) a weight of at least about 7 and at least one of a 1% warp to 1% fill ratio of at least about 4:1, a 1% fill to 1% bias ratio of less than about 1:1, a 1% warp:1% fill to 1% fill:1% bias ratio of at least about 1:1, a 10 lb. warp to 10 lb. fill ratio of less than about 0.5:1, a 10 lb. fill to 10 lb. bias ratio of at least about 1:1, and a 10 lb. warp:10 lb. fill to 10 lb. fill:10 lb. bias ratio of less than about 0.
