I've been reading some old threads on RPF concerning clothing materials (example: https://raypeatforum.com/community/threads/polyester-is-dangerous-and-bad-for-your-health.42419/). There are a couple questions I couldn't find answers to there that I figured someone on here might know about off-hand:

• Is acetate nearly as bad as polyester or is the difference in general negative effect negligable?
• If you have polyester parts of a piece of clothing (for instance a polyester inner-lining for a leather jacket) but it makes no contact with your skin, is the negative effect still substantial?

The main negative effect I'm thinking of is male fertility, but I'm also wary of concerns around ion/electrical fields and how polyester can effect them (concerns brought up by https://twitter.com/NgoloTesla, again I don't quite understand this stuff yet, or whether these are even legitimate concerns).

I intend to do further research and experimentation and apologise for my present ignorance in this area.
