Tensile properties of Textile Fibers :

Mechanical Properties of Textile Fibers

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

Mechanical properties of fibers:

Tensile Properties

Twisting/Torsional Properties

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 –

Tenacity                         Elastic recovery

Breaking extension      Yield point

Work of rupture           ❾ Yield stress

Initial modulus             Yield strain

Work factor                  Breaking load

Work recovery             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.

Load-Elongation curve for a fiber

 

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.
