Because the clothes dryer I use is the solar powered one out in the back yard, the only lint I collect is the stuff from my navel. Because I wear only natural fibres (long habit from volunteer firefighting) this lint will be mostly cotton but I don't think it has the same attractiveness as Sandra's, nor the same rate of accumulation.

But, seriously, many seem unaware of some of the reasons behind particular qualities of cotton; it's mostly cellulose and 'pure' cellulose will wick water extremely efficiently. The nap of flannel traps a reasonably thick layer of air, which is why it feels warm but even a smooth finish will wick moisture from the skin and the moisture warms up quickly, which is why cotton sheets feel comfortable next to the skin. Under a blanket (itself the insulator) you feel warm and, on hot and sweaty nights, the cotton wicks the sweat away.

When I was at Mawson, the standard outer garments were made from Ventile cotton; it never rains so there is no need for such garments to be waterproof. The cotton was "long staple" (and thus strong) and the fabric was 125 threads/inch, about as closely woven as you could get. Such a close weave meant that the wind was kept out but, just as importantly, increased the quantity of cellulose per unit area, increasing the rate at which water (from sweat) could be wicked through the garment.

"Wicked", as they say.
