Synthetic fibres are made of polymers. Unlike natural fibers, synthetic fibres are made
from petroleum based chemicals or petro chemicals. Petrochemicals are subjected to various
chemical processes to obtain synthetic fibres. Due to this, they are called Synthetic fibres or
artificial. We can easily identify the fibers whether it is natural or synthetic by fibre burning
test. Unravel several warp and weft yarns. Using tweezers hold the yarn to the edge of a flame.
Observe, the changes. If it smells like burning hair, the yarn is wool or silk. If it smells like
burning paper, the yarn may be cotton, or rayon. If the yarn melts in the flame, it is a synthetic
fibre such as nylon and acrylic.
