%hat is &ber$
It is defined as one of the delicate, hair
portions of the tissues of a plant or animal
or other substances that are very small indiameter in relation to there length.
A fiber is a material which is several
hundred times as long as its thick.

%hat is +e,ti-e Fiber
Fibres have been defined by the Textile Institute as
units of matter characterized by
flexibility,
fineness
high ratio of length to thickness.

!ther characteristics might be added, if the fibre is to be of anyuse for general textile purposes, a sufficiently high temperature
stability and a certain minimum strength and moderate
extensibility.
The characteristic dimensions of fibres are the basis of their use
and need to be stressed
individual fibres "or elements of a continuous filament# weighonly a few micrograms
their length$width ratio is at least %&&&%

.enera- (ro(erties of+e,ti-e Fiber$
Textile fiber has some characteristics which differ
between fiber to Textile fiber.
Textile fiber can be spun into a yarn or made into a
fabric by various methods including weaving, knitting,
braiding, felting, and twisting.
The essential re'uirements for fibers to be spun into
yarn include a length of at least ( millimeters, flexibility,
cohesiveness, and sufficient strength.
!ther important properties include elasticity, fineness,
uniformity, durability, and luster.
