Fibre properties (Mechanical, Chemical and Thermal)
Mechanical Properties
Tensile strength (cN/dtex) :
Chemical Properties
Hydrophobicity: Hydrophilic
Moisture regain (%): 12%
Thermal Properties
Flammability: Cellulosic fibres such as cotton, hemp jute etc. burns with a steady flame and smells like burning paper or leaves. The ash is greyish and easily crushed.
