You think cutting through a tree won’t dull scissors? Fabric is made from plant fluff or hair.

More seriously - Yes you can sharpen them but many fabric stores no longer offer the service regularly. Some knife sharpeners will do it but others won’t. My scissors can be sent back to the maker to be sharpened but then I would be without my fabric scissors for weeks. If you do it yourself you will fail.
