One of our "hat" manufactures has shifted to making masks and gowns.  They are clear the masks are not N95's, but they are making them to hospital provided specs.

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,
