Can wool be made felt proof?

I finished a scarf using 100% wool yarn, and I was wondering if there’s any chemical to apply to the wool to make it not felt anymore.

I googled the words “anti-felt chemical additive”…and the short answer to your question is YES.

There was a lot of other links to visit.

Where to find this product? What is the commercial name?
More research might turn up the answer.

Does anyone else here at KH know?
