What Is a Chemical Test for Fabric Identification and How to Perform a Burn Test?
Learn how chemical tests like the burn test help identify fabric types by observing burn behavior, smell, and ash residue safely.

Chemical tests for fabric identification can be quite effective. One common method is the burn test, where a small sample of the fabric is burned to observe its reaction, smell, and ash residue. For example, cotton burns quickly with an afterglow and smells similar to burning paper. Synthetic fibers like polyester melt and drip, producing a chemical odor. Always conduct these tests in a controlled, ventilated environment to ensure safety.
