A number of technical methods are available for fibre identification including:

1. Microscopy
   • Identifying the fibres with the help of a good microscope
   • The test can easily distinguish between fibres.
2. Solubility test
   • Immersing the fibres in various chemicals for some hours
   • Used mainly to identify fibre blends
3. Burning test:
   • Recognizing the composition of fibres by moving them slowly towards a small frame and observing the reaction to heat, how they burn, burning odour and the residue
4. Dry tearing test:
   • Tearing the fabric and observing the length of the broken fibre end
5. Wet tearing test
   • Applying a drop of water on the fabric and observing the behaviour of wet place during tearing
