A cleaning agent prepared by heating fat or oil with sodium hydroxide.
The raw materials required for making soap are:
    - Vegetable oil of olive, coconut, cotton seeds.
    - Sodium hydroxide.

Bakelite are the thermo-setting plastics formed by the condensation and polymerization of formaldehyde and carbolic acid (Phenol).
Its uses are:
    - It is used to make the handles of cooking utensils.
    - It is used to make water tanks.
    - It used to make the electrical fittings.
    - It is used to make the covers of different devices.

Plastics are the artificial materials made by the polymerization of carbon containing monomers like ethene, vinyl, etc.
Plastics materials are used more than other materials because:
    - They are cheapen, lighter and stronger.
    - They are available in different shapes, sizes and colors.
    - They can be recycled and remolded into any desired shapes.
    - They are durable and are...

The process by which a large number of simple monomers are combined to give a polymer is called polymerization.

A polymer is a very large and complex molecule formed by the combination of many simple and small molecules.
The two types of polymers are:
    - Natural polymers: wool, silk, natural rubber, etc.
    - Synthetic polymers: polythene, nylon, artificial rubbers, etc.

The fibers which are made artificially by chemical process are called synthetic fibers.
Its characteristics are listed below:
    - It is strong and elastic fiber.
    - It doesn't wrinkle.
    - It absorb less water and dries up easily.
    - It has low melting point.
Its advantages are listed below:
    - It is used to make clothes.
    - It retain their creases.
    - They are not attacked by insects.
    - They are...

Fibers are the thread like structure which is long, strong and elastic that are used to make ropes, clothes, nets, etc.
Naturally occurring fibers are called natural fibers. They are used for making clothes. They are of two types i.e plant fibers and animal fibers. Plant fibers are obtained from plants and are used for making sacks, bags, ropes, etc. And animal fibers are obtained from animals and are used for making different types of clothes.
