Identification of fibres using Burning Test

Identification of fibres using Burning Test:

Burning test tells us about the composition of fibres. i.e., whether the fibres of a fabric

are from a plant / animal source or are man-made. Follow the steps mentioned below

to conduct the burning test:

Take out a few strands of fibres from a yarn

or a fabric and then burn them with the help

of a candle flame or a match stick. Observe

the following points and record your

observations :

- The behaviour of the fibres on approaching

the flame, in the flame, on burning, and

the residue left after burning. Since

different types of fibres have specific burning

pattern, one can recognize them accordingly.

Limitations of the burning test - 

The result of the burning can be confusing if the fabric is made by mixing two or more types of fibres or yarns.
