If the linen smell is gone / almost gone, I would not return it to the case you got it with as it seems like the issue. I've seen and read about many linen wraps getting fuzzy and / or separating after cleaning attempts. A new 1x2 black vinyl hard case with pocket and strap is like $30 on amazon. Let the cue wrap continue to air out as much as possible and toss that old case unless it is a matched set and then the case lining should be replaced.
