Did you know that not all polyesters are created the same? You may have heard of fabrics made from Avora polyester or Trevira polyester, but you may not know that these aren’t just “name brands.” The terms “Avora” and “Trevira” (technically, AvoraFR® and TreviraCS®) actually indicate significant differences in the chemical structure of the polyester fibers.

One way that these fibers are different is in the way the fibers respond to flame (and thus to the flame retardancy of the fabric milled from these fibers). This doesn’t mean that other polyester fabrics are not flame retardant (some are, some aren’t), but rather that Avora and Trevira fabrics tend to respond a little differently than other polyester fabrics when under flame.
