Have you thought about making woven products with the UHMWPE you're presumably using? I want to replace my daily-carry satchel, which is leather, and the 200 grams of leather is a big chunk out of my 1500-gram satchel budget. I'd actually thought about building a machine to unbraid UHMW fishing line and thread it onto a bobbin for weaving. And 20–30 denier was about what I was hoping for; I feel like 20–30 denier UHMW twill would make for a satchel that was satiny, lightweight, impossible to stain, easy to clean, abrasion-resistant, and damn near bulletproof.
