> I have a new found respect for man-made fibres like polyester, polypropylene etc as producing those fibres is so much cleaner than natural goods, and instead of having to spend a lot of energy getting the fabric to "feel" right, you just modify the properties of the fibre by changing how its produced.

I wonder how rayon fits in this picture. It's a semi-synthetic, made from natural cellulose. In terms of comfort, it is probably my favourite synthetic fibre, but the manufacturing process is still pretty nasty.

I think the real trouble with rayon, at least in my experience with it, is that it seems to be slightly less durable than chewing gum, so you have to replace the garments more often.
