Hi Henry:
I can't imagine what would cause the felt to shred. The only thing I can think of is something sticky on the strings. Some felt is horizontal and some is vertical, the way the layers of felt are stacked for thickness. I have seen many vertical dampers that are sewn in the middle, perhaps the ones you have are for grand pianos. But then I don't know why they would behave any differently in either piano. I confess I don't really know that much. You might contact PianoForte Supply, Jergen may know what is going on and have some suggestions.

Good luck.

Note the one damper that is 'new'--the upper (in the picture) felt is literally coming apart.
Note the low-midrange dampers that are ORIGINAL--they are not shredding. They look to my unpracticed eye as though they are made of a different kind of felt. Note how they are holding the impression of the strings they have been damping.
Note how the same dampers that are clearly shredding, actually look nice and neat when they are carefully position in the piano. But when they raise from the string, the shredding will cause them to raise irregularly.
Note three hi-range dampers, which are (I THINK) originals. Starting to shred.
