I'm busy burn testing my enormous haul of fabric from an apperal factory. I can't seem to find any info on how lycra impacts the burn. Anybody know?

My best bet has been to compare burns from marked bolts to unmarked. With that info, along with standard burn charts, I have nailed down most of my fiber contents.

This is a mere guess but I read that Lycra consists of about 85% polyurethane. This PU burns with a bright flame and a stinging odor and it drips and foams (is that the correct verb?) during the burning process, according to German Wikipedia. Hope that helps a bit.

Edit: I think I misread the question. I have no idea how Lycra impacts burn testing. Sorry
