What is Fibre?
All clothing material called fabric is woven out of fibres.
Types of fibers:
There are two types of fibers which can be carized on the basis of their origin and that are written as follows:
Natural fibers
Synthetic fibers
Natural fibers
Natural fibers are obtained from plant and animal sources. They occur in ready to use form. There are certain fibers which are obtained from plants and are known as vegetable fibers.
vegetable fibers
Natural fibers
This includes the following fibres-
Protein fibers like (wool and silk)
Cellulose fibers (like cotton and linen).
Cotton is used in the manufacturing of bedsheets and usually used in summers as it keeps us ventilated.
Mineral fiber (like asbestos). This is helpful in the manufacturing of mats or carpets that are used at home for decoration.
Synthetic fibers
These are also known as man-made fibers. Synthetic fibers are obtained by chemical processing of petrochemicals. The synthetic fibers can be woven into a fabric, just like natural fiber. Synthetic fibers have a wide range of use ranging from household articles like ropes, buckets, furniture, containers, etc. to highly specialized uses in aircrafts, ships, spacecrafts, health care, etc.
Synthetic fibers
Synthetic fibers and plastics are made up of molecules called polymers. A polymer is a large molecule formed by combination of many small molecules, each of which is called a monomer.
The structure of polymer can be compared to that of a bead necklace- the bead being the monomers. The process of combining the monomers to form a polymer is called polymerization.
These are man-made fibers that come from chemical resources.
They are continuous filament fibers.
They consist of multiple units that join together to form big molecules called polymer.
They are manufactured using plant materials and minerals.
For example: Viscose comes from pine trees. Acrylic, nylon, polyester come from oil and coal. Viscose is processed to form rayon.
