To identify if fabric is synthetic, perform a burn test: carefully burn a small fabric piece. Synthetic fibers like polyester melt and form hard beads; they often emit a chemical smell. Natural fibers like cotton, on the other hand, burn to ash and smell like burning paper.

Questions and answers

What does synthetic fabric smell like when burned?
Synthetic fabric usually emits a chemical or plastic-like smell when burned, unlike natural fibers.
How can you tell natural fabric from synthetic without a burn test?
You can inspect the fabric texture and appearance or perform a water absorption test, as natural fibers usually absorb water better than synthetic ones.
Is the burn test safe to perform at home?
Yes, but it should be done carefully in a controlled, ventilated area using small fabric samples to avoid fire hazards.
