A. Tensile properties
Tensile properties indicate 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 fiber.
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 fiber.
Initial modulus
Initial modulus is the stress needed to double the length of a fiber.
Yield stress
Yield stress is the stress for which the fiber 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 fiber to recover its original size and shape. It is the ratio of elastic extension to total extension.
B. Flexural properties
It is the property or behavior shown by the fiber or material when we bend it. The importance of Flexural properties is required when we wear cloth.
C. Torsional properties
It is the property of fiber 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.
D. Frictional properties
Frictional properties are due to the friction between the fibers. These 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.
