Reviving last year's discussion... I see that Handeman plugged my company, Fly Market Kitemaking Supply. Thanks! I'm a kitemaker, so I'm sure you're all going to teach me a few things about rockets, but it seems we use the same fabric. Fly Market stocks three brands of ripstop nylon -- Texlon, Paratex, and Chikara -- totalling more than 60 colors. The biggest difference between them is the coating sprayed onto the fabric at the mill. The coating inhibits UV damage, and decreases porosity. Texlon has the heaviest coating, which makes it fairly stiff (almost papery). Chikara has a lighter coating, giving it a fairly soft hand. Paratex is in the middle. As for colors, I'd think that the four fluorescent shades of Paratex would be great for high-visibility chutes, but as I said, there are a lot of colors to choose from.
You'll find all the fabric info at https://www.flymarketkites.com/34-oz-ripstop-nylon/
. And I'm always happy to send out free sets of swatches, if you want to feel the fabric and check the colors. Just PM me with your mailing address or send an e-mail. Thanks, looking forward to working with the rocketry community.
