Try higher quality detergent. Adding something antibacterial should help too. Use fabric softner. In wash or dryer or both. Don't blast on high heat in dryer. Use med heat. Those are my ideas.
I have a very old house. In the spring and summer months it sweats and swells leaving a odor in my clothes and body. I have to shower everyday or face retribution from my co-workers as:"Damn man, you stink like shit", or ""Did you sleep with a dead dog?" I'll ask my PCP for more Info on this one.
