I am very certain it was the chemical reaction from the CA glue,=
 not the cloth and
felt.  Those same bolts of material were used on many other=
 pianos with standard
glue methods with no problem.  In fact the same material was used=
 in re-doing the
plate trim and it still is in fine shape eight years later, so it=
 is not affected felt.
I also use CA glue for occasional looseness in bridge pins with=
 no problem.  Perhaps
it reacted with some chemical in the felt cloth manufacture. =
 Speculation.

Are you sure it was the CA glue?  I have used CA glue to secure=
 loose bridge pins sometimes applying the CA directly to the pins=
 without removing the wire.  I have never noticed any tendency=
 toward corrosion in these areas.  I have also tacked understring=
 felt with CA at times (though not the thin understring cloth)=
 and not noticed any problems either.

A note and little warning aside from the subject matter=
 discussed.  Perhaps you know this,
but avoid using CA glue for gluing plate felt & cloth.  I tried=
 doing this with CA glue when I
did not want to wait for the drying time needed by other glues I=
 normally use.  Much to my dismay
in several weeks I had to completely restring the piano because=
 the chemical reaction had
severly rusted the strings where they contacted the felt and=
 cloth.  Not a good way to learn.
Thought this might be of some interest.  I learned sometimes the=
 quick fix is not always the
best fix.
