Most of our laundry therefore comes out of the spin dryer and goes straight into a tumble dryer for a couple of hours of treatment. The faster the spin, the less tumbling is required.
There's a lint catcher so that fluff, lint, dirham coins and keys that come out of the laundry don't go into the works of the drying machine, nor down the exhaust pipe. And the lint is always the same colour as the majority of the most recent load. Obviously the drying process removes some of the fabric from the clothes that are being dried.
My question is this: does line-drying the laundry produce the same amount of lint? You can't tell, because it would blow away never to be seen again. Is it wearing clothes that causes them to wear out, or washing them?
One for the long winter evenings: it is theoretically possible to gather up all the lint and fluff from the dryer, spin it into yarn, and knit some socks or a sweater.
