What is Textile Fiber?
Properties of Textile Fibres:
All fibers are not textile fiber. To become a textile fiber it should have some characteristics. One important characteristic is length; to become a textile fiber it should have at least 5 mm length then it will be spin able and it must be supple, flexible and strong enough.
Classification of Fiber Properties:
Commonly textile fiber can be classified in two ways:
A. Primary properties of textile fibers
B. Secondary properties of textile fibers
A. Primary properties of textile fibers:
I have given the physical properties name with their unit. A textile fiber should have the following physical properties. They are as follow:
To identify a textile fiber, following properties plays an important role. Chemical properties are-
The properties that describe a material's ability to compress, stretch, bend, scratch, dent, or break
All of textile fibers have its own structure by which it can be identify.

7. Biological Properties of Fiber:
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. The behaviors which are shown by a textile material when it is subjected to a torsional force is called torsional property.
Textile fibers are the materials at natural or artificial origin which has a high length to width ratio and with suitable characteristics which can be converted into yarn and fabric for clothing by interlacing or interloping; may be natural or manufactured; the smallest component, hair like in nature, that can be separated from a fabric. In simple words, a slender filament or fine strand of sufficient length, pliability, fineness, flexibility and strength to be spun into yarns and woven into cloth is called textile fiber.

The properties that describe a material's ability to compress, stretch, bend, scratch, dent, or break
- Young's modulus / Stiffness
- Tenacity
- Specific modulus
- Tensile strength
- Compressive strength
- Shear strength

- Elasticity, etc.
- Electrical conductivity or specific conductance is a measure of a material's ability to conduct an electric current
- Conductivity is the reciprocal (inverse) of electrical resistivity, ρ (Greek: rho), and has the SI units of siemens per metre (S·m-1)
- Resistance –Ohms (e.g. Resistance of Dyneema is > 1014 Ohm)
- Thermal conductivity
- Flammability
- Glass transition temperature
- Melting point
