Is there still lanolin on the fibers of wool after it is processed? Any knitters out there? If there is a residue, it might interfere with the spray holding properly. This is just a suggestion.
It is also better to spray the back of the fabric rather than the batting, if you don't already do this. Batting is very porous and lets the spray sink into it. The fabric holds the spray on top.
Try contacting the maker with your situation, They would be the ones who could help the most with this problem.
