Natural vs. Synthetic Fabrics: Which Burns Faster?

Flammability depends on fiber content, weave, and chemical treatments. Generally, natural fibers (cotton, linen) ignite more easily and burn faster than synthetics (polyester, nylon) due to lower ignition temperatures and higher surface area.

Weave and Treatments

• Loose weaves (e.g., gauze) burn faster than tight weaves (e.g., canvas) because air circulates more freely.
• Chemical treatments can increase or decrease flammability. Flame retardants slow flames, but some wrinkle-resistant finishes may increase flammability.

Relative Flammability

More flammable: Cotton, linen, rayon, silk, wool, acrylic, acetate.

Less flammable: Polyester, nylon, spandex, olefin, modacrylic.

Even less-flammable fabrics can burn under high heat or open flame. Always exercise caution with any fabric.
