The gap between stitches in a shirt is a gaping hole to a virus.

AFAIK, masks are (mostly) not for the virus, they're for the droplets. The droplets are much larger.

T-shirt fabric was found to be 75% effective at stopping droplets from spreading in a study[1]. That’s pretty remarkable considering and 95 masks are 95%! I guess that makes them N75 masks?

the "95" part of N95 means it filters 95% of particles smaller than 0.3 microns. A sieve that can filter 95% of rice particles doesn't make a N95 mask either.
