Perspiration odor can be completely washed out of clothes by adding a cup of baking soda to your laundry. Also, use warm water as opposed to cold and set your washer on the longest cycle or a "soak" cycle if you have it.
If the odor is particularly strong, I suggest rinsing the load twice. The finishing touch (when possible) would be to hang your laundry outdoors.
That load should be totally fresh and clean!!
