Textiles can be made from many materials. These materials come from four main sources: animal (wool, silk), plant (cotton, flax, jute), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic). In the past, all textiles were made from natural fibres, including plant, animal, and mineral sources. In the 20th century, these were supplemented by artificial fibres made from petroleum.
* jute <------ #tocheckout
cotton / jeans
* polyester 185T / 210T / ...
"210T refers to the yarns per square inch in the warp and weft directions."
* "aluminized polyester"
used on http://www.ferrino.it/en/catalog/tents/99045-tent-svalbard-3-t9-4000 ("aluminised Ripstop polyester")
or for better tarps (~5X more expensive)
* PE = polyethylene:
supposedly not so good for tents (rain!)
" Polyester rainfly before and after (8 min hosing) - boring but good. By the way, the polyester fabric on this particular prototype didn't have an exterior silicone treatment. It was just polyurethane on the underside. All our current fabrics are sil/pu with silicone on the outside plus polyurethane on the underside. They repel water really well and they don't let it through."
* BoPET / Mylar:
* "space [emergency] blankets" (reflects 90% of body heat back)
* Insulation for houses and tents, reflecting thermal radiation
* Light insulation for indoor gardening.
* "4000mm double-coated aqua rating with fire retardant and SPF50 UV coating"

GOOD TENT BRANDS
heard about them:
* kiwi tents (via alen berlin / jana)
* what do +fotr +mat have?
* +tin oversees a rope thread factory line? (also working on PhD in metallurgy)
* antirust stuff,
* polyurethene (via Igor)
"Getting a smooth, blemish-free finish with oil-based polyurethane is within your grasp if you follow the steps in this article. Oil-based polyurethane varnish brings out the wood’s natural beauty or wood grain. Our 4-step approach shows you how to apply the varnish successfully. A good-quality natural-bristle brush, a reasonably dust-free, well ventilated space and some patience are all you need."
* magnesium cement
* plastic tubes (for monkey huts etc)
