Kim - I am not the expert...just giving you my personal experience...but I am focusing on all the "more environmentally friendly as can be" compounds and thus the safer alternative that many experts now consider are the Borax/Borate based fire retardants.
http://www.universalmaterials.com/support/about.html These guys are in my own backyard. Regarding your Proban, I read that with cotton fibre there is a need for a "mordant" in order to "sticky" the retardent in order embed into the fibre. I think that is why the commericial companies use the chemicals with the big long names. Also, in my fire supression days, we weighed the fact that we could get "burnt to the crisp" versus "wearing the Nomex or other gear for the one week or two weeks" of wearing the gear. But to wear it 24/7....some other reader may know more. Good Luck Phillip Wolfe --- Kim & Garth Travis <[EMAIL PROTECTED]> wrote: > Thank you for the information.
