What are the mechanical properties of textile fibers?

The mechanical properties of textile fibers include strength, elongation, elasticity, wear resistance and elastic modulus.

Strength of fiber: the strength of fiber refers to the resistance of fiber to external damage, which to a large extent determines the durability of textile goods.

The strength of the fiber can be expressed by the strength of the fiber, which refers to the continuous increase of the load of the fiber, until the fracture of the larger load. The unit of legal instructor is Newton (N) or centinewton (cN). It used to be expressed in terms of grams or kilograms.

As a result of fiber strength and fiber thickness are concerned, so to the fiber of different thickness, ** strength without comparability, therefore, commonly used relative strength to represent the strength of fiber. The relative strength is the tensile strength per unit linear density (per cent or per denier). The legal unit of measurement is N/ Tex or cN/ Tex. It used to be expressed in grams per denier.

Fiber elasticity: fiber and its products in processing and use, to withstand the role of external forces, and the corresponding deformation. When the external force is removed, one part of the fiber deforms and the other part does not. According to the characteristics of fiber dimension, the fiber deformation can be divided into three parts, that is, when the external force removed immediately after the recovery of this part of the deformation called elastic deformation; When the external force is removed, the part of deformation that can slowly recover is called slow elastic deformation. When the external force is removed, the part of the deformation which cannot be recovered is called plastic deformation.

The elasticity of a fiber is its ability to recover from deformation. The commonly used index to indicate the elastic size of fiber is the elastic recovery rate of fiber or the resilience rate. It refers to the rapid elastic deformation and a certain time of slow elastic deformation percentage of the total deformation.
