Definite qualities required by fiber

Each of the fiber types has its unique properties.Based on these properties we decide the usage of a particular type of fiber for a specific use.For example,Nylon is a synthetic fiber, known for its strength, elasticity, toughness, and resistance to abrasion, has commercial applications including clothing and carpeting.Cotton fiber consist of a single long tubular cell. Its length is about 1200-1500 times than its breadth. used for making clothes.It has wide variety of use in Apparel industry to

Each fibre has particular properties which help us to decide which particular fibre should be used to suite a particular requirement. Certain fibre properties increase its value and desirability in its intended end-use but are not necessary properties essential to make a fibre. Thus it is very essential to know the individual aspects and specific properties of each kind of fibre.

Fibers are broadly classified into Filament yarns and Staple Yarns on the basis of their physical structure.Filament yarns are measured in yards or meters.
