Fabric burn tests are done as a form of fibre identification, as not all fibres react in the same manner.
Pay attention, this is a quick one!
The fabric tested is a square of Broadcloth, which is a woven fabric. In this instance the fabric is a polycotton, which consists of a blend of cotton and polyester fibres.
When doing a polycotton burn test, a combination of fibre characteristics can be observed:
COTTON burn characteristics:
Cotton is a natural cellulose fibre (short, plant fibres).
Fabric is flammable
Catches on fire easily - flare up when lit
Burns easily - continues to burn
POLYESTER burn characteristics:
Polyester, a manufactured fibre, is a byproduct of the petroleum industry, which is similar to plastic.
Fabric shrinks away from flame
May flare up
Melts rapidly, even after extinguished
Not always self-extinguishing
Black smoke - fumes can be hazardous
No ash, only beads
Residue is hard, discoloured beads
Chemical smell - smells like burning plastic
Also, check out the Cotton and Polyester burn tests, to see how each fibre reacts individually!
