synthetic fibres

Synthetic fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long, linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers, they generally have the same common properties. Generally, they are known for being:
Heat-sensitive
Resistant to most chemicals
Resistant to insects, fungi and rot.
Low moisture absorbency
Electrostatic
Flame resistant
Density or specific gravity
May pill easily
Low melting temperature
Often less expensive than natural fibers.
Easy to wash and maintain.
Before synthetic fibers were developed, artificially manufactured fibers were made from cellulose, which comes from plants. These fibers are called cellulose fibers.
Advantages[edit]
Synthetic fibers do not depend either on an agricultural crop or on animal farming.
They are generally cheaper than natural fiber.
Synthetic fibers possess unique characteristics which make them popular dress material.
They dry up quickly, are durable, readily available and easy to maintain.
More stain resistant than natural fibres
Disadvantages[edit]
Synthetic fibers burn more readily than natural
Prone to heat damage, they melt relatively easily
Prone to damage by hot washing
More electrostatic charge is generated by rubbing than with natural fibres
There are several methods of manufacturing synthetic fibers but the most common is the Melt-Spinning Process. It involves heating the fiber until it begins to melt, then you must draw out the melt with tweezers as quickly as possible. The next step would be to draw the molecules by aligning them in a parallel arrangement. This brings the fibers closer together and allows them to crystallize and orient. Lastly, is Heat-Setting.
