All textiles can burn, but their properties are extremely different. For example, did you know that you should never wear acrylic clothing near a bonfire?

What you should know before you light a bonfire.

If you're buying clothing for children, you should pay particular attention to the product’s flammability. Ask the sales personnel or check the label yourself.

Structure is important

The structure of the material makes a difference to how it burns. Thin, lightweight textiles that provide plenty of air catch fire and burn quickly. Materials that have a woolly, coarse or porous surface are more flammable than materials with a smooth, impermeable surface.

Billowy clothes burn fast

It is easier for wide-fitting, billowy clothes to come into contact with flames than tight-fitting clothes. Wide sleeves, floaty dresses and lightweight, trailing scarves are particularly vulnerable. These clothes also burn faster than close-fitting clothes because there is more air available. Remember this when you buy costumes for children.

Clothes may also contain chemicals that are harmful to health and the environment. tells you which chemicals you should avoid.

All fabrics will burn,  but some are more combustible than others.  

Untreated natural fibers such as cotton, linen and silk burn more readily than wool, which is more difficult to ignite and burns with a low flame velocity.

The weight and weave of the fabric will affect how easily the material will ignite and burn. 

Fabrics with a tight weave - wool, modacrylic, 100 percent polyester and those that are flame-retardant treated are good choices. Heavy, tight weave fabrics will burn more slowly than loose weave, light fabrics of the same material. The surface texture of the fabric also affects flammability. Fabrics with long, loose, fluffy pile or "brushed" nap will ignite more readily than fabrics with a hard, tight surface, and in some cases will result in flames flashing across the fabric surface.

Most synthetic fabrics, such as nylon, acrylic or polyester resist ignition. However, once ignited, the fabrics melt. This hot, sticky, melted substance causes localized and extremely severe burns. When natural and synthetic fibers are blended, the hazard may increase because the combination of high rate of burning and fabric melting usually will result in serious burns. In some cases, the hazard may be greater than that of either fabric individually.

Curtains, draperies and other articles in the home can have their burning rates reduced with flame retardants applied through chemical treatment. Such flame-retardant treatment after manufacturing is not recommended for clothing.

The design of clothing also may influence the flammability of the garment. Full, long and loose garments tend to ignite easily and have a higher rate of burning since more material is exposed to the atmosphere than with close-fitting garments.

Flame-retardant materials used in garments require special laundering to maintain the flame-retardant effectiveness. Flame-retardant materials should be washed only with standard detergents. Clothing labels usually provide adequate information about the care of the garment.

Recommended clothing for minimum flammability would be sturdy jeans, tight-fitting jerseys, blouses without frills, jersey pajamas with no ruffled nightgowns, clothes with tight-fitting or short sleeves, clothes made from flame-retardant fabrics, sweaters, shirts and dresses that are not loose, flowing or too big. Clothing made from flame-retardant fabric is recommended especially for the elderly.

In terms of flammability, silk may be the worst with a high burning rate, which may be increased by the dyes and other additives to provide color.

  • Cotton and linen also have a high burning rate but this can be alleviated by the application of flame-retardant chemical additives.
  • Acetate and triacetate are as flammable or slightly less flammable than cotton. However, they can be made flame-retardant with chemical treatment.
  • Nylon, polyester and acrylic tend to be slow to ignite but once ignited, severe melting and dripping occurs.
  • Wool is comparatively flame-retardant. If ignited, it usually has a low burning rate and may self-extinguish.
  • Glass fibers and modacrylic are almost flame-resistant. These synthetic fibers are designed and manufactured to possess flame-retardant properties.
