Detergent is not a disinfectant.
Detergent (and even good old soap) doesn't kill _all_ bacteria and spores, but it's pretty efficient in killing most of active bacteria and fungi (link: http://www.ncbi.nlm.nih.gov/pm... ). That's more than enough to delay the onset of mold long enough for the clothes to dry.
