Fibres have wide variations in chemical, electrical, mechanical, optical and other properties and the properties of a fibrous product naturally depend on the properties of the fibres of which it is composed. Not only the average values but also the range or statistical distribution is important. A typical classification of such fibre properties with some examples is given below:

Classification Of Fibre Properties

• Geometric

1. Length
2. Cross-section
3. Crimp

• Physical

1. Density - Linear, bulk
2. Thermal - melting, transitions, conductivity
3. Optical - birefringence, refractive index, lustre and colour
4. Electrical - dielectric constant, resistivity
5.  Surface - roughness, friction
6. Mechanical - tension, compression, torsion, bending, shear

• Chemical 

1. Response to acids, alkalis, oxidation, reduction and heat 
2.  Sorption - moisture, dyes
3. Swelling - anistropy
