Tensile properties

Tensile properties indicates how a material will react to the forces being applied in Tension. Some tensile properties are given below -

Tenacity

Tenacity is the maximum strength to break a fibre.

Breaking extension

It is expressed in percentage. It is the ratio of elongation at break to the initial length and multiple of hundred.

Work of rupture

The total energy needed or work done to break a fibre.

Initial modulus

Initial modulus is the stress needed to double the length of a fibre.

Yield stress

Yield stress is the stress for which the fibre or material starts yielding.

Work factor

It is the ratio of work of rupture to the product of breaking load and breaking extension.

Elastic recovery

The tendency of a fibre to recover its original size and shape. It is the ratio of elastic extension to total extension.

Flexural properties

It is the property or behaviour shown by the fibre or material when we bend it. The importance of Flexural properties is required when we wear cloth.

Torsional properties

It is the property of fibre or material when a Torsional force is applied on it. Here Torsional force is a twisting force that is applied on the two ends of the material in two opposite direction.

Frictional properties

Frictional properties is due to the friction between the fibres. This properties are shown during processing. Too high friction and too low friction is not good for yarn. Therefore it is an important property when yarn manufacturing and processing.
