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.
Claims62
A woven sailcloth comprising warp yarns and fill yarns and having a 1% warp of at least about 125 and/or a warp efficiency of at least about 17.
A woven sailcloth comprising warp yarns and fill yarns 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, wherein the woven sailcloth has a 1% warp of at least about 125 and/or a warp efficiency of at least about 17.
A woven sailcloth comprising warp yarns and fill yarns and having a weight of at least about 7 and at least one of:
- (a) a 1% warp to 1% fill ratio of at least about 4:1,
- (b) a 1% fill to 1% bias ratio of less than about 1:1,
- (c) a 1% warp:1% fill to 1% fill:1% bias ratio of at least about 1:1,
- (d) a 10 lb. warp to 10 lb. fill ratio of less than about 0.5:1,
- (e) a 10 lb. fill to 10 lb. bias ratio of at least about 1:1, and
- (f) a 10 lb. warp:10 lb. fill to 10 lb. fill:10 lb. bias ratio of less than about 0.5:1.
A woven sailcloth having a weight of at least about 7 and comprising warp yarns and fill yarns 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, wherein the woven sailcloth has a 1% warp of at least about 125 and/or a warp efficiency of at least about 17, and wherein the woven sailcloth has 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 0.5:1.
A method of making a woven sailcloth comprising warp yarns and fill yarns, which method comprises weaving warp yarns and fill yarns 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, whereupon a woven sailcloth comprising warp yarns and fill yarns is made.
A method of making a sail, which method comprises assembling panels of sailcloth, at least one panel of which is woven sailcloth comprising warp yarns and fill yarns and having a 1% warp of at least about 125 and/or a warp efficiency of at least about 17, wherein the at least one panel of woven sailcloth is assembled into the sail with load paths oriented along its warp yarns, whereupon a sail is made.
A method of making a sail, which method comprises assembling panels of sailcloth, at least one panel of which is woven sailcloth comprising warp yarns and fill yarns 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, wherein the woven sailcloth has a 1% warp of at least about 125 and/or a warp efficiency of at least about 17, whereupon a sail is made.
A method of making a sail, which method comprises assembling panels of sailcloth, at least one panel of which is woven sailcloth having a weight of at least about 7 and comprising warp yarns and fill yarns, wherein (i) the at least one panel of woven sailcloth has 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, a 10 lb. warp:10 lb. fill to 10 lb. fill:10 lb. bias ratio of less than about 0.5:1 and (ii) the at least one panel of woven sailcloth is assembled into the sail with load paths oriented along its warp yarns, whereupon a sail is made.
A method of making a sail, which method comprises assembling panels of sailcloth, at least one of which is a panel of woven sailcloth having a weight of at least about 7 and comprising warp yarns and fill yarns 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, wherein the woven sailcloth has a 1% warp of at least about 125, a warp efficiency of at least about 17, 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 0.5:1, whereupon a sail is made.
