I’ve noticed this as well. Even a cotton poly blend will be noticably stickier by the end of the day. In the winter, if I don’t do anything too exerting or slop food down the front of it, I can get a couple of days out of a good cotton shirt.

I recently got a job where I have to wear this awful poly button down, and the thing gets so stinky so fast. Just one of the reasons I hate that shirt.
