[skin concerns] Why does polyester smell more than cotton even though the sweat is present in both and why is a mixture of both better than just 1 of them?

Beauty Tips For Body Care
I want to know this because large amounts of sweat would cause me to have breakouts and smell which is why I want to make a proper decision on thisMany sources on the internet state that cotton smells less than polyester when you sweat because the sweat is soaked up by the cotton so that bacteria cannot consume the sweat on your skin which would usually cause the bad smell to arise. But I don't get how this makes sense since the sweat that gets soaked up is basically in direct contact with the bacteria of your skin which means that they could simply consume the dry sweat byproducts from the shirt as well which would cause the shirt to smell. Also, there might be sweat residue on your skin as well, even in that case.Also I read about a claim that a mixture of both materials would have the combined benefits of both of them which would mean:Since cotton is able to soak up sweat very well, it can be very helpful to absord all the sweat your body gives of and due to the fact that polyester doesn't soak up fluids very well it is able to get rid of the fluids better than the cotton so that the cloths don't feel wet anymore.The problem that I have with this statement is that I don't get how the materials could have been layered to have the stated effects.Could you explain how they could have been interweaved so that the stated effects make sense?
