Critical fiber length definition

WebFiber length is critical in processing of fibers and yarns and in the translation of fiber strength to yarn strength. In general, a longer fiber length is preferred. Textile fibers are either staple or filament length. Staple fibers range from 2 to 46 cm; filament fibers are of infinite length. All natural fibers except silk are of staple length. WebThe fibers are longer than a critical length which is the minimum length necessary such that the entire load is transmitted from the matrix to the fibers. If they are shorter than this critical length, only some of the load …
