TYPES OF FIBERS

Fibers can be defined as strings or yarns made for the creation of different kinds of fabric
materials. Generally speaking, fibers are divided into two main types. This can either be natural
or synthetic fiber. While natural fiber consists of objects such as silk, cotton, and fleece,
synthetic fiber consist of nylon, polyester and rayon. They are normally sewn or woven into
textures or items. Other additional materials that are made of fibers are paper and fiberglass.
Natural fibers can be said to have their origin either from plants or other natural sources whose
existence are not affected by human activities. Synthetic fibers on the other hand are also known
as man-made fibers and are therefore those that manufactured by humans in factories. It can be
noted that there are many various types of synthetic fibers whose origin is conventional sources
(Claridge, 2016).
Fiber investigation has developed to become one of the most common method that is
employed in the identification of criminals. The fibers are normally deposited either on the
suspect’s body or the victim’s body in the event that they come in contact. This exchange
however depends on the nature of the garments worn by both the suspect and the victim during
the time the crime is being committed. There are garments that shed a lot of fibers compared to
the others. For instance, a neatly woven attire will have a greater tendency of not shedding fibers
compared to their roughly knitted counterparts (Claridge, 2016).
Fibers are very important in the determination of a case since they are used as physical
evidence. However, this does not mean they are entirely correct. The amount of time taken
during the contact between the suspect and the victim determines whether the fiber shall be
deposited or not. There are various methods that are used in the analysis of fiber that have been
collected at the crime scene. These methods are applied to both synthetic and natural fibers. The
use of magnifying lens has been considered as the most common and reliable method since it
