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.
