This is a felt fabric made from what is basically heat-shrink electrical tubbing polymer (30% shrink) used primarily as hat forms and exotic-looking costumes.
If not fully shrunk when initially formed and if it were warmed again (sanitizing), it will continue to shrink down to 70% its original size.
Interesting idea for creating mask forms. However, it would likely be as effective as a home-sewn felt mask.
Thank you,
