Exercise 1 ( Page No. : 26 )

  • Q1

    Classify the following fibres as natural or synthetic:

That is why it is also a natural fibre.

    Synthetic fibres: Nylon, Polyester

    Nylon: It is man- made fibre. It is a thermoplastic silky material generally used for making rope and thread.                                                                    Polyester: It is the derived form of coal, petroleum and water that’s why it is called synthetic fibre.
