%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.
