High-strength/modulus fabrics basic properties

A liber or a filament (a continuous form of fiber) is the fundamental unit of textile materials. It has a unique combination of high strength (tensile, bending, torsional, or compression), high flexibility (i.e., low modulus), extensibility, and shows recoverability on deformation. Most of these properties are observed in one principal direction, which is known as the axis of the fiber. Since all textile structures from one to three dimensional (yam, fabric, or braids, etc.) are built using this basic structural unit, these stmctures also possess the above unique properties.
