To remove mold from clothing you need to get to it as quickly as possible. The longer the mold has been there the harder it is to get out. If you're dealing with white fabric that can be bleached then by all means use bleach in your wash cycle as this is the best way to remove mold. Another way to remove mold from clothing is to add approximately 3/4 cups of white vinegar to your wash load. Repeat if necessary to make sure all the mold is gone then wash again with just detergent to rid the clothes of any vinegar smell.
