Fibers can be divided into natural and man-made (synthetic) substance, their properties can affect their performance in many applications. Nowadays, man-made fiber materials are replacing other conventional materials like glass and wood in a number of applications. This is because man-made fibers can be engineered chemically, physically, and mechanically to suit particular technical engineering. In choosing a fiber type, a manufacturer would balance their properties with the technical requirements of the applications. Various fibers are available to select for manufacturing. Here are typical properties of the sample natural fibers as compared to the properties of man-made fibers.
