Warp oriented woven sailcloth

North has introduced a warp oriented woven polyester-- "Radian". I am a big fan of Dimension's spectra/poly blend, Hydranet Radial. I believe Contender also has a warp oriented polyester out now too. Anybody have a sense how these fabrics compare? No stats on the north site and Dimension is pretty stingy with the web info too.

Hi Sailman-- For a woven? I was pretty sure that there really have not been woven products suitable for radial construction before Hydranet- And I figured that North was trying to compete with that.

I am intersted in the comparison between Radian and Hydranet, because I suspect that there are some interesting tradoffs. For instance, I think that in making the Hydranet, they have to ease off on the heat, to avoid melting the spectra. I imagine this would result in a a looser weave, and hence more bias stretch-- but at the same time a softer hand. But the spectra shoull be MUCH less stretchy when the load is aligned with the warp. True?

I also wonder about the degree of resination in the Radian, relative to the Hydranet (which seems to have relatively little). Will the longer term flex-fold performance of the hydranet be better than the Radian, because is relies less on resin to maintain weave stability? Or is the Radian so tightly woven that heavy resination is not required?

The nicest radial cruising sails that I have seen are made from DP Square Weave, which is why all of our Quicksilver's here are made from it. Really nice stuff.

Can't find the thread you refer to searching on "Warp oriented" and "radian". I do believe that the "crimpless" warp oriented woven is a significant advance, true?

I'll second the recommendation on Square Weave. It holds up very well. As far as the Radian goes it will be interesting to see how it holds up 2- 4 years down the road. In the past warp oriented polyester depended on the resin to control the bias stretch. This resin broke down quicker than most other race finishes and left the customer with some very sleazy radial panels.

That made some very interesting transitions between sections, even more so if you were doing radial corners and crosscut body panels.

I hope they have it figured out. Trickle tech down for the rest of us, but I'm not going to hold my breath for 3 years to find out

if it really works as advertised.

"I'll second the recommendation on Square Weave."

I am confused-- Peacefrog says he uses DP "Square Weave" in radial sails. Surely, you and he are referring to the Hydranet radial for triradial sails? Presumably the regular Hydranet (wihc has a square pattern of rip stop spectra yarns) would be for crosscut sails?

Was wondering, if you weaved different color threads in a precise pattern, could you have a sail where the threads would change color under load? Would this be helpful for trim?

No I'm not referring to Hydranet. We were discussing woven polyester. Hydranet is is up a couple price points to say the least.

Try this link. The microscopic pictures are telling. Let's just hope it isn't Shark Skin!

Ted Hood was doing this stuff 40 years ago! Yet another reason why Big Blue is a useless organization if it is peddling this stuff as "innovation".

No one was building radial Dacron sails 40 years ago, even Mr Hood, so if he was weaving cloth for it, he must not have been very successful, so your point is sort of stupid. Besides, they usually don't grant a patent on something if it isn't innovative and the Radian weaving process is protected by a worldwide patent. BTW, Sharkskin suffered from the yarn manufacturer's inability to deliver a consistent product to the loom. And the "useless organization" stepped up and replaced every one made from questionable material.
