I own five kilts and have been wearing them since 2001. One is a very well made and expensive hand made wool kilt that is well constructed and looks fantastic, the other four are the acrylic variety - they are well constructed and look fantastic and all four (together) cost less then the wool.
I wear the wool when I am going to weddings, burns dinners ect. The others I wear to games, fairs, ren fests, or pub crawling.

I would not be welding, building a camp fire, or cooking next to an open flame in any of them - mainly because I would not want to ruin any of them.

I have never caught fire in my less expensive kilts, of course I dont stand directly over or next to open flame (even in my wool kilt or while wearing jeans) and I have yet to run into stray flames as I walk around at events, and I have never been hit by lighting.

Me thinks this is much too do about nothing. While I understand that acrylic kilts will burn, (so will many things we wear) most folks are not going to put themselves in a position to burst into flames.

A google search of "Kilts on fire" - the first article about a kilt on fire comes from the year 1896 - my bet it that it was not a pakistani kilt
