Aside from all the issues concerning the braiding, and the twisting, etc., and just looking at the jacket dielectric aspect, if the jacket were teflon, it would not be very much of a sonic penalty to leave it on.HOWEVER, it is VERY unlikely that you have ordered a CAT5 cable with a teflon jacket, almost invariably if they say the cable is "teflon" they mean the twisted pair insulation and NOT the jacket.
If you have found a source of the rare and mythical teflon jacked CAT5, please share this source with everyone.
You can still just braid the 4 pairs per cable jacket set as one leg of the braid, in fact, if the jacket is PVC, it should be possible to braid the jackets, and remove the jackets after they have been braided, and them pull the wires tight after the jackets have been removed. You would have to kind of peel the jacket away from each section as it weaves in and out of the braid pattern, but it could be done, and it would keep the 4 pairs together so you wouldn't have to handle the 4 pairs loose while atempting to braid them as a set.
If you do it this way, then I would recommend a secondary wrap after removing the jackets, of some teflon gas line tape, while the czble is being stretched taut, so the twisted pairs are not too loose with espect to one another.

John and others thanks everyone for the ideas. I tested the jacket of the cables I received - they burn with a cigarette lighter so not teflon. The insulation however just melts no burning - similar melting properties as teflon pipe thread.It will take me a few weeks before I have time to play with this. Will post my observations after auditioning carefully.
