is polyester batting flammable

Is polyester batting flammable? The short answer is yes. Like most synthetic fibers, polyester batting will burn if it meets an open flame. It behaves differently from natural fibers, though, and knowing how it reacts to heat helps you choose the right batting for quilts, pot holders, costumes and home decor.

How Polyester Batting Reacts to Heat

Polyester is a thermoplastic, so instead of catching fire quickly, it tends to shrink away from a flame and melt. That melting is the real concern: hot, sticky drips can cause burns and may keep burning once they ignite.

Cotton vs Polyester Batting

• Cotton chars and burns but doesn't melt, which is why it's often preferred for pot holders and oven mitts.
• Polyester is lightweight, loftier and resists mildew, but it shouldn't sit near high heat.
• Wool is naturally more flame resistant than either.

Tips for Safer Use

Press poly batting with a cool iron and a pressing cloth, keep finished projects away from stoves, heaters and candles, and check the label if you need flame retardant batting for specific uses.
