    TEXTILE

http://en.wikipedia.org/wiki/Textile

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.

    "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:
    for floors


        * nylon:
    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:

"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."
