Mechanical Properties of Textile Fibers

The properties that describe a fiber strength, elongation, elasticity, abrasion resistance, modulus of elasticity etc.

Mechanical properties of fibers:

❶ Tensile Properties

❷ Twisting/Torsional Properties

❸ Flexural Properties

Tensile properties of textile fibers

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

❶ Tenacity ❼ Elastic recovery

❷ Breaking extension ❽ Yield point

❸ Work of rupture ❾ Yield stress

❹ Initial modulus ❿ Yield strain

❺ Work factor ⓫ Breaking load

❻ Work recovery ⓬ Creep etc.

Analysis of stress-strain/load-elongation curve

When an external force is applied to a fiber, it is balanced by the internal force development in the molecular structure of the fiber. By increasing the stresses, material will deform and follow the load-elongation/stress –strain curve.

Here,

Elastic region: In the region from O to A, the fiber shows elastic region and deformation is called elastic deformation. At region, Hooke’s Law is obeyed according to which stress is directly proportional to strain.

Plastic region: In the region from A to B, the fiber shows plastic region and deformation is called plastic deformation. Plastic deformation which means that it can deform without an increase in the applied load.

Yield point: The point A is called yield point.

Breaking point: The point B is called breaking point. The fiber will break at this point.
