Micro fiber is often used to clean plastic lenses, and it is also a synthetic material. So it's possible your crushed velvet would be OK. Keep in mind that the fabric does simply rest gently on the horn. If you have it as a grip, as my photo shows (barely), there is pressure and friction. Even on the bell piece there could be some pressure/friction when it is in the case. Picture the amount of vibration the case endures as it rides in a vehicle.
If you want to try that fabric, I'd start by rubbing vigorously on some shiny metal (ideally brass or something as soft) for a while and look for signs of abrasion. If it looks good, I MIGHT try it on the horn, taking it off regularly to examine the surface beneath the guard.
