Erm...I would be grossed out if I knew your dinner napkins were tossed in with diapers and femme naps...
Just me tho
I have a dog who is prone to seizures and he soils the carpet when he has a seizure. I usually clean up with towels, but I sort them for a different wash than my regular load of clothes. For my clothes, I don't use high/hot temperatures either, I may use hotter temperatures for things that are highly soiled, full of bacteria, blah blah, like my bathroom rugs or the dog's towels.
Things like cloth diapers need the hottest water possible to get rid of e.coli. Conversely, blood gets out better with cold water (oddly enough). Food stains on dinner napkins need to be treated first and then washed accordingly to the type of stain (grease based vs. wine, etc).
