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.
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.
