Material question

I have an unusual requirement for a cotton-like material which will not accumulate surface charge as readily as nylon or teflon fibers. This material needs to be moisture resistant like nylon, and also needs to be transparent to radio frequency energy. Most of all, it needs to be durable and resist tearing and fraying. We have tried heavy cotton canvas and it is not sturdy enough for our application at the 9 oz weight we tried.
Any suggestions will be greatly appreciated.

Does anyone read this forum? I have done some further study on the triboelectric process and have actually found a standard, ASTM F23.20.05 which covers this phenomenon for hazardous vapor duty materials. Are there any textile jocks on this site who could help me with this?

Unfortunately this is not a very active forum. You do need to describe your application better to get help. There are many possibillities. Is wear resistance most important? what about cost? Kevlar is tough but expensive. Static can be addressed by additives such as humectants or conductive materials. How much radio transparency is needed? What frequency.

Cotton/polyester?

Polyurethane coated cotton?

Dacron?

Dacron is DuPont's trade name for their Polyester.

I agree Polyester/Cotton blend sounds like the way to go.

I asked my friends in the textile industry if they could help. Their friends can make strong, water- resistant cotton duck.

How much do you need?
