Here's a quick tip I learned from friends who regularly go car camping: they always bring a large size salad spinner with them, just in case they find themselves needing to wash, then dry a t-shirt, socks, or intimates...
I've got several technical synthetic material athletic shirts, socks, and tights/sleeves I prefer to hand wash and hang dry throughout the week immediately after workouts (they can accumulate a funk quickly, the sweat hog I am). But now summer is gone and temperatures have dipped, they're taking longer to air dry in our bathroom, and I don't want to trek to the laundromat numerous times throughout the week. No bueno, when all I want is my running sleeves the next day.
A large capacity salad spinner (like this 11.5 x 11.5 x 7.2" OXO model) can speed up the drying process significantly, working under the same principles as the rinse/dry cycle inside a washing machine, albeit one item at a time and requiring the effort of your own muscles. Just think of it as a miniature gym machine!
You can easily cut down the line/hang drying process in half with a salad spinner (works great with cashmere items too), though just like the washer/dryer, you don't want to overstuff the spinner while drying for the fastest and most thorough removal of water. You might also want to purchase two spinners, one for clothing drying duties, others for your greens, and kept in separate areas lest you unintentionally flavor your next meal in very personal fashion.
