is dacron flammable

Is Dacron flammable? Yes. Dacron is a trade name for polyester, a synthetic fiber that will burn when exposed to an open flame. It doesn't flare up the way loose, dry cotton can, but it does react to heat in ways every sewist, upholsterer and crafter should understand before choosing it for a project.

How Dacron Reacts to Heat and Flame

Polyester tends to shrink away from a flame, then melt and drip. Some untreated polyester may stop burning once the flame source is removed, but the molten drips stay hot and can stick to skin or spread fire to nearby materials. That's why polyester flammability is about more than just whether it ignites.

Dacron vs. Natural Fibers

• Cotton and linen char and burn to ash rather than melting.
• Wool is naturally slow to ignite and often self-extinguishes.
• Dacron polyester melts, which matters for clothing worn near heat.

What to Look For

For upholstery, cushions, drapery or public spaces, check whether a fabric or batting is labeled flame retardant or tested to a specific fire code standard. Untreated Dacron batting and upholstery wrap are great for softness and loft, but keep them away from open flames, heaters and fireplaces.
