Question

The raw material used in the preparation of synthetic fibre:
A) Petrochemical
B) Petrol
C) Gasoline
D) Coal tar

Answer 1

Hint: We have to know that the fibres can be naturally found or synthetically made. Synthetic fibres can be chemically derived by humans through chemical synthesis whereas natural fibres are derived from living organisms. These fibres are synthesized from polymers having small molecules.

Complete answer:
We will now study about the natural and synthetic fibres. The compounds that are used for making fibres that are raw material can be petroleum based products which is petrochemical. For synthesizing different fibres different chemical compound is used. Nylon, acrylic are synthetically made fibres which are most commonly used nowadays. Synthetic fibres are more reliable than natural fibres that have good stretching, waterproofing, stain resistance and generally more durable than natural fibres. Synthetic fibres have a good quality of withstanding water and strain. But with many advantages synthetic fibres also have many disadvantages like they have low melting point, they melt easily, they are more prone to heat damage and many more. All fabrics are obtained from fibres but fibre can be naturally or synthetically made. Thus it can be concluded that the substances used to produce such fibres are extracted from raw materials such as chemicals based on petroleum or petrochemicals further these materials are polymerized into a chemical that ties together two adjacent atoms of carbon.

So the correct option for this answer is option A) as explained above.

Note:
We must have to know that the fibres are made from polymers which are generally derived from repeating units of monomers for example: nylon, polypropylene. There are different materials by which these fibres can be obtained; it can be coal, water and mostly petrochemical based raw materials.
