More Shepardson readings
Following up on this. After drying and folding laundry, the T-shirts seemed especially crackly and zappy. So I decided to see what my crude little charge-meter shows. Supposedly the meter is meant to read negative charge.
Over the crackly T-shirts:
No negative charge.
Then over the non-crackly towels, also pulled and folded a few seconds earlier:
Strong negative charge.
I moved the meter back and forth several times, carefully moving nothing but my shoulder joint, to be sure it wasn't a hand position artifact or something like that. The meter snaps down to zero over the T-shirts each time without requiring a manual discharge. This probably means a definite positive charge in that area, not just a zero charge. (I really need to build a 'clean' two-way meter now that I know the concept works!)
Labels on both sets of items say "100% cotton". I don't believe the labels; both of these items feel part synthetic in terms of 'slipperiness' and elasticity. This charge difference implies that the shirts and towels are made of different materials. Whatever those materials are, they can't both be 100% cotton. 
No negative charge.
